Shield Break Cable Joints

The GTSIS1 heat shrink shield break cable joints manufactured by Nexans are designed for Medium & High Voltage power cables – unarmoured, plastic insulated cables with Cu wire or Cu tape screen, to accommodate either crimped or mechanical shearbolt connectors.

These Nexans HV cable joints are suitable for jointing medium/high voltage (MV-HV) 33kV single core polymeric insulated cables with copper wire screens (35-1000sqmm) up to 33kV (42kV).

Nexans GTSIS shield break cable joints provide screen interruption in the joint in order to separate earthing system networks (AC 20kV – Impulse 70kV).

The heat shrink cable joints can be supplied with Single (GTSIS “L”) or Double (GTSIS “L2”) earthing exits to allow screen transposition and cross bonding. These cable joints enable you to cross bond the screens of all three circuits in a safe manner that has been Tested and Certified to Cenelec HD 629.1 S2 & IEC 60502-4.

Technical Features

Along each section, a standing voltage is induced. In ideal cross-bonding systems the three section lengths are equal, so that no residual voltage occurs and thus no screen current flows.

GTSIS W type for CWS Cables
GTSIS AW type for CTS Cables
GTSIS FC type for Al Foil Screen Cables

MC types are supplied with GPH mechanical connectors. The outer sheath is restored with heavy wall adhesive lined tubing or in case of limited space with a wrap-around sleeve with or without Al foil.
