15kV, 3/C Medium Voltage Joint
Straight joint for three-core 12-17.5kV, extruded dielectric shielded power cables


The Innovative Power Products MVJ 3150T series joint is a heatshrinkable system for jointing three-core shielded 15kV (12-17.5kV) extruded dielectric medium voltage power cable. The kit has field control material to control electrical stress over the connectors and at the shield cutbacks and provide internal moisture seals. Insulating tubing and shielding tubing reinsulate and reshield the areas over the spliced conductors. Tinned copper mesh and braids reestablish the shielding across the joint. A tough abrasion resistant black jacketing tube or wraparound jacketing sleeve provides the joint with external moisture seals and mechanical protection.

MVJ 3150T kits provide a lightweight, compact, and environmentally sealed system for splicing three-core extruded dielectric shielded power cable. These features allow the installation of this jointing system in duct systems, vaults, sub-mersible or direct-buried applications. This system provides a total environmental seal; joint failures in flooded vaults are eliminated.


  • MVJ 3150T 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.


  • MVJ 3150T 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 shielded or Unishield® power cable. The MVJ 3150T kits can be used for size transitions within the actual kit’s cable use range. Four (4) kit sizes cover all cable sizes from 2 AWG through 1000 kcmil. 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 MVJ 3150T kits are individually packaged, three-core shielded cable joints. Everything is included to splice one, three-core cable, with or without grounds, less the external grounding hardware and butt-splice and ground wire connectors. External grounding components can be included as a kit option. Connectors can be supplied in the kits; subject to factory quote. See section 5 for connector information.

Ordering Information

1. Find your cable size in the selection guide above and identify the kit catalog number. This kit will be all that is needed to splice one three-core cable less the phase and ground wire connectors. Confirm the dimensions when at the extremes of the size range.
SPACE
2. Add the mod kit letter designation as needed to change the base kit:

G - sealed grounding kit (Gmod)
P - cable cleaning kit (Pmod)
     
Examples
     
Example 1:
To splice 3/C, 2 AWG, 15kV cable to the same cable size or within the kit size range:
MVJ 3151T

  Example 2:
To splice 3/C, 250 kcmil, 15kV cable to a 3/C, 350 kcmil 15kV cable with a cable cleaning kit:
MVJ 3152TP




* CONNECTORS: To have connectors supplied in the kits, please refer to Section 5 in this catalog for connector selection information. The connectors must be ordered separately but can be packaged within the kits if detailed information is supplied.
