35kV, 3/C Armored Medium Voltage Joint
Straight joint for three-core armored 33-36kV, extruded dielectric shielded power cables


The Innovative Power Products MVJA 3350T series joint is a heatshrinkable system for jointing three-core armored 35kV (33-36kV) extruded dielectric medium voltage power cable. The kit has field control material and heatshrinkable field control tubing to control electrical stress over the connectors and at the shield cutbacks and provide an internal moisture seal. Insulating tubings and shielding tubing reinsulate and reshield the areas over the spliced conductors. Tinned copper mesh and braid reestablish the metallic shielding across the joint. A galvanized steel wraparound case combined with an abrasion resistant black jacketing tube or wraparound jacketing sleeve provide the joint with external moisture seals plus mechanical protection.

MVJA 3350T kits provide a lightweight, compact, and environmentally sealed system for splicing three-core armored extruded dielectric, shielded power cable. These features allow the installation of this jointing system in duct systems,vaults, submersible or direct-buried applications. This system provides a total environmental seal; joint failures in flooded vaults are eliminated.


  • MVJA 3350T kits are factory engineered to provide fast and easy installations with reliable performance.

    All MVJ kits are designed to meet or exceed the requirements of the applicable sections of the following cable and cable accessory standards: IEEE-404, IEEE-48, ICEA-66-524, ICEA-66-516, and ANSI C119.2.


  • MVJA 3350T 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 cable constructions including: metallic tape, drain wire or Unishield® armored power cables. The MVJA 3350T kits can be used for size transitions within the actual kit’s cable use range. Three (3) kit sizes cover cable sizes from 1 AWG through 1000kcmil. When preparing the cable ends, no pencilling of the cable insulation is required.

These factory engineered kits are supplied with everything that is necessary to rebuild the cable including ground braids and constant force springs. The braids are internal to the joint and do not have sufficient length for external grounding.

The MVJA 3350T kits are individually packaged three-core armored cable joints. Everything is included to splice one three-core armored cable, with or without grounds, less the butt-splice and ground wire connectors. Connectors can be supplied in the kits; subject to factory quote.
