3/C, 25kV Medium Voltage Termination with Boot
Class 1 terminator for three-core 25-28kV extruded dielectric shielded cable with up to 3 grounds

The Innovative Power Products MVT 42510 series Class I termination kits are heatshrinkable terminators for three-core armored or unarmored 25kV (22-28kV), extruded dielectric shielded medium voltage cables with or without ground wires. The MVT 42510E series terminations are for applications where the terminators are exposed to the elements such as precipitation or direct outdoor sunlight.

MVT 42510 series kits provide a lightweight compact alternative to other three-core termination methods. There are no compounds to mix and pour and no labor-intensive taping procedures. MVT 42510 series terminators provide a rugged, low cost and reliable cable termination.

  • MVT 42510 series kits are factory engineered to provide fast and easy installation with reliable performance.

    All MVT kits are designed to meet or exceed the requirements of IEEE-48 for Alternating Current Cable Terminations.

  • MVT 42510 kits cover a wide range of conductor sizes and shapes. They accommodate out-of-round or off-tolerance cables, in both round and sector shaped conductors. The standard kits fit all types of three-core cable constructions with or without ground wires, including: metallic tape shield, drain wire shielded, lead covered and Unishield® power cables. MVT 42510 series kits can be used on armored cables when no separate armor terminator is used. The kits are based on the single-core MVT 2530 series kits with additional components to convert the three-core cable into three, individual single cores. The forty-eight inch (48”) tail length allows for easy training of the termination in switchgear or at the riser in overhead transition applications. Three (3) kit sizes cover cable sizes from 2 AWG through 1000 kcmil.

Ordering Information

1. Select the kit catalog number by the cable size. The kit contains everything needed to terminate a 3/C cable less the connectors for sheltered (indoor) use. Confirm the dimensions when at the extremes of the size range.
2. Add the mod kit letter designation as needed to change the base kit:

E - sheds are required for exposed
(outdoor) environments. (Emod)
P - cable cleaning kit (Pmod)
G - sealed grounding kit (Gmod)
