+description: >
+ When to use: Shielded medium-voltage power cable rated 5 kV through 35 kV (5, 15, 25, and 35 kV classes) for primary distribution in commercial, institutional, and industrial facilities. Covers EPR- and XLPE-insulated single- and multi-conductor MV-90/MV-105 cable; selection of voltage class, insulation level, and shield type; procurement; pulling and installation in duct bank, conduit, cable tray, and direct burial; splicing and terminating; and field acceptance testing of primary feeders from utility service entrance or substations to switchgear, unit substations, MCCs, and transformer primaries.
+ Not intended for: Low-voltage power wiring 600 V and below (see [[sync/conductors-and-cables]]); the underground duct bank, conduit, and manhole systems that house MV cable (see [[sync/underground-ductbank]]); the medium-voltage switchgear, breakers, and interrupter switches the cable feeds (see [[sync/medium-voltage-switchgear]]); secondary unit substations and their internal secondary wiring (see [[sync/secondary-unit-substations]]); power-factor capacitor banks and their feeder cables (see [[sync/power-system-capacitors]]); high-voltage transmission cable above 46 kV; and bare overhead or aerial covered conductors on poles.

+# Scope {toc}
+
+## This specification covers the selection, procurement, installation, splicing, termination, and field acceptance testing of shielded medium-voltage power cable rated 5 kV through 35 kV for primary distribution systems in commercial, institutional, and industrial facilities. {note}
+
+## The scope encompasses single-conductor and multi-conductor extruded-dielectric cable insulated with ethylene-propylene rubber (EPR, Type MV-105) or cross-linked polyethylene (XLPE, Type MV-90), in voltage classes of 5 kV, 15 kV, 25 kV, and 35 kV, installed in concrete-encased duct bank, conduit, cable tray, underground vaults, or by direct burial. {note}
+
+## Primary feeders in scope run from the utility point of delivery or facility substation to medium-voltage switchgear, unit substations, motor control centers, and transformer primaries, on campus distribution loops and industrial plant primary systems where power is distributed above 2,000 V. {note}
+
+## A medium-voltage cable failure interrupts the entire downstream distribution served by the feeder, and the dominant failure modes — termination and splice workmanship, shield discontinuity, and damage during pulling — are introduced during installation rather than manufacture. The requirements of this standard reflect that consequence and concentrate on the field operations that determine in-service reliability. {note}
+
+## This standard is inseparable from [[sync/underground-ductbank]], which governs the duct bank, conduit, and manhole systems through which most cable in scope is pulled; the cable terminates into equipment governed by [[sync/medium-voltage-switchgear]] and [[sync/secondary-unit-substations]]; and coordination with the low-voltage systems of [[sync/conductors-and-cables]] is required where MV feeders supply transformers stepping down to building distribution. {note}
+
+## This standard does not cover low-voltage cable rated 600 V and below, the raceway and civil duct-bank systems that house MV cable, the switchgear and interrupter equipment fed by the cable, capacitor-bank feeders, high-voltage transmission cable above 46 kV, or bare overhead and aerial covered conductors. {note}
+
+# Referenced Standards {toc}
+
+## Equipment, materials, and installation shall comply with the latest adopted edition of each of the following unless a specific edition is cited.

+
+# Quality Assurance {toc}
+
+## Cable manufacturers shall be regularly engaged in the production of shielded medium-voltage cable to ICEA S-93-639 or ICEA S-97-682 and shall hold current UL 1072 listing for the products furnished.
+
+## Splicing and terminating are the operations most determinative of in-service reliability, because removing the semiconducting shield and reconstructing the electrical-stress geometry by hand at every joint and termination introduces stress concentrations that the factory dielectric never sees. This standard therefore qualifies the technician, not only the materials. {note}
+
+### Cable splices and terminations shall be made only by technicians certified by the splice and termination kit manufacturer for the specific kit, voltage class, and conductor size installed.
+
+### The Contractor shall submit documented evidence of at least three years of medium-voltage cable splicing and terminating experience for each technician performing the work.
+
+### Semiconducting shield material shall be removed only with manufacturer-approved scoring and removal tools, and shall never be removed by knife scoring that notches the insulation.
+
+## Each cable run, splice, and termination shall be field tested and accepted before the feeder is energized.
+
+## A single voltage class, insulation type, and shield construction should be standardized across a project wherever the system voltage permits, so that one set of splice kits, termination kits, and trained technicians serves the entire installation.
+
+# Environmental and Service Conditions {toc}
+
+## The voltage class of the cable shall match the system nominal operating voltage; a 13.8 kV system requires 15 kV class cable, not 5 kV class cable. {note}
+
+## The most common error in medium-voltage cable specification is selecting a voltage class below the system operating voltage. Voltage class denotes the system band the cable insulation geometry is designed for, not a withstand margin. The 15 kV class is by far the most common for US campus, healthcare, university, and large commercial primary distribution because the prevalent 13.2 kV and 13.8 kV systems fall within it. {note}
+
+### The cable voltage class shall be selected to equal or exceed the system nominal voltage band as scheduled.
+
+```datasheet
+label: Voltage Class
+type: radio
+options:
+ - 5 kV (systems 2.4-4.16 kV)
+ - 15 kV (systems 4.16-13.8 kV)
+ - 25 kV (systems 14.4-22 kV)
+ - 35 kV (systems 23-34.5 kV)
+default: 15 kV (systems 4.16-13.8 kV)
+```
+
+## Insulation level expresses how long the cable insulation must tolerate the phase-to-phase voltage appearing across an unfaulted phase during a ground fault, which depends on the system grounding and the protective relaying. The 100% level suits solidly grounded systems that clear a fault in one minute or less; 133% suits systems that clear within one hour or are impedance/resistance grounded; 173% suits ungrounded systems or those that operate faulted indefinitely. {note}
+
+## Most facility systems are not solidly grounded with sub-minute fault clearing, so the default insulation level for the typical facility application is 133%. Specifying 100% level on a system that does not meet its grounding and clearing conditions under-insulates the cable for the fault duty it will actually see. {note}
+
+### The insulation level shall be selected to match the system grounding configuration and fault-clearing time as scheduled.
+
+### The insulation level shall not be specified below 133% unless the system is solidly grounded with fault clearing of one minute or less.
+
+```datasheet

+ - 173% (ungrounded or indefinite faulted operation)
+default: 133% (impedance/resistance grounded or fault cleared in 1 hr or less)
+```
+
+## The installation method governs the ampacity derating, the required jacket and armor, and the mechanical protection the cable receives, so it shall be established before conductor size is finalized. {note}
+
+### The installation method shall be coordinated with [[sync/underground-ductbank]] and applied as the basis for ampacity derating.

+drawing_ref: "MV cable routing plan"
+```
+
+## The default design value for soil thermal resistivity (RHO) in direct-buried and duct-bank ampacity calculations is 90 °C·cm/W; values above 90 °C·cm/W reduce ampacity and require a larger conductor for the same load.
+
+## The designer shall verify the actual site soil RHO and use measured values when available for direct-buried and duct-bank ampacity calculations.

+
+# Cable Construction {toc}
+
+## Insulation type is the central material choice. EPR (Type MV-105) operates at 105 °C and XLPE (Type MV-90) at 90 °C; the 15 °C higher operating temperature of EPR yields a meaningful ampacity advantage, and EPR is more flexible and easier to terminate in the confined manholes and switchgear cubicles typical of facility work. EPR is therefore the 80% default for institutional and facility primary feeders, while XLPE remains a valid lower-cost choice for straightforward duct-bank runs. {note}
+
+### The insulation type shall be EPR (Type MV-105) or XLPE (Type MV-90) as scheduled, and the type selected shall be consistent across all cable furnished for a given feeder.
+
+```datasheet
+label: Insulation Type
+type: radio
+options:
+ - EPR / ethylene-propylene rubber (MV-105, 105 °C)
+ - XLPE / cross-linked polyethylene (MV-90, 90 °C)
+default: EPR / ethylene-propylene rubber (MV-105, 105 °C)
+```
+
+## Insulation thickness is fixed by the ICEA S-93-639 / NEMA WC74 tables for the selected voltage class and insulation level and shall never be specified below the standard minimum. For 15 kV at 133% level, the minimum is 175 mils for both EPR and XLPE; the specifier shall confirm the value for the actual class and level against the current edition. {note}
+
+### Insulation thickness shall equal or exceed the ICEA S-93-639 / NEMA WC74 minimum for the specified voltage class and insulation level.
+
+## Conductor material for facility primary feeders is standardly copper, which is the default; aluminum is a cost-driven alternative that, for equal ampacity, requires a larger conductor and correspondingly larger conduit. {note}
+
+### The conductor material shall be copper or aluminum as scheduled.
+
+```datasheet
+label: Conductor Material
+type: radio
+options:
+ - Copper
+ - Aluminum
+default: Copper

+
+## Conductor stranding shall comply with ASTM B8 for concentric round or ASTM B496 for compact round; compact round is commonly specified for medium-voltage cable to reduce overall diameter and improve the seal of pre-molded fittings. {note}
+
+### Conductor stranding shall be Class B concentric round, compact round, or compressed as scheduled, complying with ASTM B8 or ASTM B496.
+

+options:
+ - Class B concentric round (ASTM B8)
+ - Compact round (ASTM B496)
+ - Compressed
+default: Compact round (ASTM B496)
+```
+
+## The metallic shield carries charging and fault return current and establishes the ground reference around the insulation. A helical copper tape shield is the standard construction for shielded feeders; concentric neutral construction is used where the system neutral must be continuously grounded along the entire run, as in some direct-buried distribution. The two are not interchangeable: they have different fault-current return capacity and different installation handling. {note}
+
+### The metallic shield shall be copper tape or concentric neutral as scheduled.
+
+```datasheet

+options:
+ - Copper tape shield (5 mil, helical)
+ - Concentric neutral (full neutral)
+ - Concentric neutral (one-third neutral)
+default: Copper tape shield (5 mil, helical)
+```
+
+## Copper tape shield shall be a minimum of 5 mil thick applied helically; the overlap determines the fault-return path quality, with 12.5% being the minimum and 25% commonly specified for a more robust return path. {note}
+
+### Copper tape shield overlap shall be a minimum of 12.5%, and shall be 25% where scheduled for enhanced fault-return capacity.
+
+```datasheet
+label: Copper Tape Shield Overlap
+type: radio
+options:
+ - 12.5% overlap (minimum)
+ - 25% overlap
+default: 25% overlap
+```
+
+## Concentric neutral sizing shall be a full neutral for direct-buried runs; a one-third neutral is acceptable only for duct-bank runs where the available fault current is limited by system relay coordination. {note}
+
+## The jacket protects the shield and insulation from the installation environment and governs flame and smoke behavior inside buildings; the material shall be selected for the installation environment and any flame or low-smoke requirement. {note}
+
+### The cable jacket shall be PVC, LLDPE, HDPE, or LSZH as scheduled.
+
+### Where PVC jacket is specified, the minimum jacket thickness shall be 80 mils for cables up to approximately 1.5 in outside diameter per ICEA S-93-639.

+
+## Cable installed in cable tray or conduit inside buildings shall meet the FT4 flame-propagation requirement of IEEE 1202.
+
+## Cable configuration is single-conductor or multi-conductor. Single-conductor construction is the dominant choice at 15 kV and above and for most facility feeders; multi-conductor (3C or 3C with ground) is common at 5 kV for compact branch feeders in tighter routing. {note}

+
+# Ampacity and Conductor Sizing {toc}
+
+## Conductor size shall be established from the NEC Table 310.60(C) series and IEEE 835 for the actual installation configuration, with all applicable derating applied. Common facility feeders fall between 4/0 AWG and 500 kcmil copper; for reference, 4/0 AWG copper EPR 15 kV in duct is approximately 260-290 A and 500 kcmil approximately 370-400 A before derating, with the exact value set by the installation conditions. {note}
+
+### The conductor size shall be selected from NEC Table 310.60(C) and IEEE 835 for the scheduled installation configuration and shall carry the connected load after derating.
+
+### All applicable derating factors shall be applied, including conduit fill above three current-carrying conductors, elevated ambient soil temperature, parallel duct groupings, and soil RHO above 90 °C·cm/W.

+```
+
+## Cable ampacity shall be coordinated with the served transformer kVA, the fuse or relay protection, and the cable impedance, so that the feeder cable is not the thermal weak link of the circuit even when the overcurrent device is correctly sized. {note}
+
+### The feeder cable ampacity shall coordinate with the upstream protective device rating and the downstream transformer kVA such that the cable is protected against overload and short circuit.
+
+## The cable shall not exceed its temperature limits in any operating state: 90 °C continuous for XLPE and 105 °C for EPR, 130 °C (XLPE) or 140 °C (EPR) emergency overload, and 250 °C short-circuit. {note}
+
+# Terminations and Splices {toc}
+
+## Terminations and splices are engineered fittings, not generic field assemblies; using a misclassed or generic fitting is a leading cause of in-service medium-voltage cable failure. Terminations shall be selected by class per IEEE 48 and splices by type per IEEE 404, matched to the cable construction, voltage class, and conductor size. {note}
+
+### Cable terminations shall comply with IEEE 48 and shall be selected by class for the indoor or outdoor service condition.
+
+### Cable splices and joints shall comply with IEEE 404 and shall be rated for the cable voltage class and conductor size.
+
+## Termination type is selected for the service condition. Heat-shrink and cold-shrink terminations are common for both indoor and outdoor use; pre-molded (push-on) terminations and separable connectors suit dead-front equipment interfaces; fluid-filled terminations serve specific outdoor applications. {note}
+
+### The termination type shall be heat-shrink, cold-shrink, pre-molded, or fluid-filled as scheduled, and shall be IEEE 48 Class 1 for outdoor or wet-location terminations.
+
+```datasheet

+```
+
+## Splice type shall match the cable construction and the splice location, which may be a manhole, a direct-buried location, or a vault. {note}

+
+## Every metallic shield shall be grounded at terminations, and shield continuity and ground resistance shall be verified, because an ungrounded or poorly grounded shield is both a personnel hazard and a cause of accelerated insulation aging.
+
+### The metallic shield shall be grounded at every termination.
+
+### Shield ground continuity shall be verified after termination.
+
+## Adequate cable slack shall be left at each termination point — typically 10 to 15 ft per termination in manholes — so that terminations can be made, future re-terminations are possible, and minimum bend radius is preserved at the tails.
+
+# Installation {toc}
+
+## Medium-voltage cable insulation and semiconducting layers are permanently damaged by exceeding the minimum bend radius or the maximum sidewall bearing pressure during pulling, so these limits shall be calculated and observed throughout installation.

+
+### The maximum pulling tension on copper conductors shall not exceed 0.008 times the conductor circular-mil area, expressed in pounds, or the manufacturer's published maximum where lower.
+
+### The sidewall bearing pressure shall not exceed 300 lb/ft, or the manufacturer's published limit where lower.
+
+### Cable shall be pulled with a manufacturer-approved lubricant compatible with the jacket and shall be monitored with a tension-measuring device during the pull.
+
+## Cable shall be installed only when the cable temperature is above the manufacturer's minimum installation temperature, because jacket and insulation are susceptible to cracking when pulled cold.
+
+## Each cable run, splice, and termination shall be identified at every accessible point — manholes, vaults, and equipment terminations — with the circuit designation, so that runs can be traced and isolated for maintenance.
+
+### Each cable shall be tagged with a permanent, legible circuit identification at every manhole, vault, pull point, and termination.
+
+## Spare conduits shall be reserved in the duct bank, and adequate bending and racking room shall be provided in manholes, in coordination with [[sync/underground-ductbank]], so that cable can be pulled, racked, and terminated without violating bend-radius limits. {note}
+
+# Testing {toc}
+
+## Field acceptance testing proves the integrity of the installed system after the operations most likely to have damaged it, and is performed before energization. The required tests are insulation resistance, shield continuity, and an AC withstand by the VLF method. {note}
+
+### Each cable run shall be insulation-resistance tested conductor-to-shield before and after the withstand test, and the results compared for consistency.
+
+### Shield continuity and shield ground resistance shall be verified for each cable run.
+
+## DC hipot testing shall not be used on XLPE- or EPR-insulated medium-voltage cable, because DC voltage injects and traps space charge in extruded dielectric, causing latent dielectric damage and post-test failures. The acceptance withstand shall instead use the very-low-frequency (VLF) AC method of IEEE 400.2. {note}
+
+### Each cable run shall be subjected to a VLF AC withstand test at 0.1 Hz, at 2.5 times U0 (the phase-to-ground rated voltage) for 60 minutes, per IEEE 400 and IEEE 400.2.

+# Delivery, Storage, and Handling {toc}
+
+## Cable shall be delivered on reels with each end sealed against moisture ingress, because moisture in the conductor strand or under the shield migrates along the cable and degrades the insulation over its life. {note}
+
+### Cable ends shall be sealed with manufacturer-supplied moisture-resistant end caps at delivery and shall remain sealed until termination or splicing.
+
+### Reels shall be stored on a firm, well-drained surface, protected from mechanical damage, and shall not be stacked or dropped.
+
+### Cable shall be protected from prolonged direct sunlight and from temperatures outside the manufacturer's storage range during storage on site.
