15kV Medium Voltage URD Joint
For single-core 15kV, extruded dielectric bare and jacketed concentric neutral power cables


The Innovative Power Products, Inc. MVJ 150UD and MVJ 150T UDJ series joints are heatshrinkable systems for splicing bare or jacketed concentric neutral 15kV extruded dielectric, power cable. It uses special materials to control electrical stress over the connector and at the shield cutbacks and provide internal moisture seals. A heatshrinkable field control tubing controls stress over the connector and shield cutbacks. Insulating tubings reinstate the cable insulation across the joint and insulating shielding tubing reshields the joint and forms an internal seal to the cable semiconductive layer. A stainless steel constant force spring clamps the neutral wires to the joint. For jacketed concentric neutral cable, a tough abrasion resistant black jacketing tube or wraparound sleeve provides the joint with external moisture seals and mechanical protection.

MVJ 150UD and 150T UDJ kits provide a lightweight, compact and environmentally sealed system for splicing bare or jacketed concentric neutral cable. These features allow the installation of this jointing system in duct systems, vaults, submersible or direct-buried applications. This joint is ideal for almost any non-tension application. The system is totally sealed. Joint failures in flooded vaults are eliminated.


  • MVJ kits are factory engineered to provide fast and easy installation with reliable lifetime performance.

    MVJ 150UD and 150T UDJ joints’ performance is based on the design and testing of the MVJ 150 series joint for metallic tape and wire shielded power cables.

    MVJ kits are designed to meet or exceed the requirements of the applicable sections of the following cable/cable accessory standard IEEE-404.

  • MVJ 150UD and 150T UDJ kits cover a wide range of conductor sizes. They accommodate out-of-round or off-tolerance cables. The MVJ 150UD and 150T UDJ 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, pencilling of the insulation is not required.

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 single-core cable, less the butt-splice 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:

P - cable cleaning kit (Pmod)
     
Examples
     
Example 1:
1/C, 1/0 AWG, 15kV bare concentric neutral cable spliced to the same cable with a cable cleaning kit:
MVJ 151UDP
