Live End Seals - MVES 250 Series
25kV Medium Voltage Live End Seal

Clear cap for single-core 22-28kV extruded dielectric, shielded power cables

About:
The Innovative Power Products MVES 250 series live end seal is a heatshrinkable system for live ending (clear capping) 25kV extruded dielectric, jacketed power cable that has been abandoned but still energized. The MVES uses an extruded dielectric plug to encasulate the conductor and special materials to control electrical stress at the plug/cable-end interface and at the shield cutbacks. A heatshrinkable field control tubing is used to control stress over the interface and at the shield cutbacks. Insulating tubings reinstate the cable insulation and insulating shielding tubing reshields the joint and forms an internal seal to the cable’s semiconductive layer. Tinned copper mesh reestablishes the metallic shielding around the assembly. An end cap covers the shielded assembly’s end. A tough abrasion resistant jacketing tube and sealants provide moisture seals and mechanical protection.

MVES 250 kits provide a lightweight, compact and environmentally sealed system for live ending jacketed power cables. These features allow the installation of this system in duct systems, vaults, submersible or direct-buried applications. The system is totally sealed. Live end failures failures in flooded vaults are eliminated.

Performance:
MVES kits are factory engineered to provide fast and easy installation with reliable lifetime performance.

MVES 250 live cap performance is based on the design and testing of the IPP MVJ 250 series joint for metallic tape and wire shielded power cables.

MVES kits are designed to meet the requirements of the applicable sections of the cable accessory standard IEEE-404.
