35kV Medium Voltage Trifurcating Joint
Three-core to three, single-core 33-36kV extruded dielectric shielded power cables


The Innovative Power Products MVJT 350T series joint is a heatshrinkable system for jointing shielded three-core 35kV (33- 36kV) extruded dielectric medium voltage cable to three, singlecore extruded dielectric power cables. The kit has a heatshrinkable cable breakout boot and jacketing tubings to convert the three-core cable into three single-core cables. After converting the three-core cable, the MVJ 350T kits are installed to complete the trifurcation. The oint can be installed on three-core armored and unarmored cables.

MVJT 050T kits provide a lightweight, compact and environmentally sealed system for splicing 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.


  • MVJT 350T kits are factory engineered to provide fast and easy installations with reliable performance.

    All MVJT 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.


  • MVJT 350T kits cover a wide range of conductor sizes and shapes. It will accommodate out-of-round or off-tolerance cables, in both round and sector shaped conductor. The standard kit fits all cable constructions including: metallic tape, drain wire shielded or Unishield® power cable. The MVJT kits can be used for size transitions within the actual kit’s cable use range. Three (3) kit sizes cover all cable sizes from 1 AWG through 1000 kcmil. When preparing the cable ends, no pencilling of the cable insulation is required.

Ordering Information

1. Find the cable’s conductor 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 to three single-core cables less the connectors and shield grounding kits.
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:
For 3/C (armored or unarmored), 35kV, 1/0 AWG cable spliced to 3-1/C, 35kV 1/0 AWG, cables with a solder-less grounding kit:
MVJT 351TG

  Example 2:
For a 3/C, 35kV, 250 kcmil cable spliced to 3-1/C, 35kV 400 kcmil cables with a cable cleaning kit:
MVJT 352TP


* 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.
