3/C, 25kV Medium Voltage Termination without Boot
Class 1 terminator for 3/C armored 25-28kV extruded dielectric shielded cable using armor terminator

The Innovative Power Products MVTA 52510 series Class I termination kits are heatshrinkable terminators for three-core 25kV (22-28kV) armored extruded dielectric, shielded, high voltage power cables when an armor terminator is used to terminate and seal the cable’s armor and jacket. The MVTA 52510E series terminators are for applications where the terminators are exposed to the elements (outdoor).

MVTA 52510 series kits provide a lightweight, compact alternative to other three-core termination methods. The MVTA 52510 series kit makes installation of the armor terminator faster, easier and the system more reliable.

  • MVTA 52510 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.

  • MVTA 52510 kits cover a wide range of conductor sizes and shapes. The standard kits fit all types of three-core armored cable constructions, including: metallic tape shield, drain wire shielded, lead covered and Unishield® cables. These kits are based on the single-core MVT 2530 series kits with core and ground wire tubings to jacket the exposed shields. The forty-eight inch (48”) tail length allows for easy training of the termination system in switchgear or at the riser in overhead applications. Three (3) kit sizes cover all cable sizes from 2 AWG through 1000 kcmil.

    If desired, a cable ‘through-passage’ fitting can be used to seal the cable jacket while allowing the jacketed cable to enter the enclosure. This fitting is less expensive than an armor terminator and much simpler to install. When a ‘through-passage’ device is used, the MVT 42510 termination should be used to protect and seal the system. This combination is generally less expensive than the use of armor terminators.

Ordering Information

1. Select the kit catalog number by the
cable size. The kit contains everything
needed to terminate one 3/C armored
cable less the armor terminator and
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)
