Features & benefits

The TS 24CSTJ A combines Cold-Shrink and bolted connector technologies for reliable undergound MV connections.

Cold-Shrink Joint :

  • compatible with synthetic insulated cables (SIC) 
  • compatible with three cores paper insulated cables (PILC)
  • compatible with: copper wire, copper tape & alu tube cable screens
  • EPDM joint body
  • UV resistive external EPDM outer protection
  • standard screen short-circuit for 1s = 5,1 kA 
  • equipped with a vapor screen for enchanced waterthightness.

Bolted Connectors :

  • multisection, from 95 to 240
  • compatible with copper & aluminium cores.
  • equipped with self-breaking screws, for a perfect torque.
  • no specific tool needed


The TS 24CSTJ A has been designed to connect  3x1 core SIC cables to 1x3 cores PILC cables, with sections from 95 to 240, whether aluminium or copper cores, on undergound MV lines.

Each core can be connected thanks to a GPH® bolted connector.


Each TS 24CSTJ A kit is made of:

- 3 EPDM cold shrink bodies.

- 3 bolted connectors (upon request)

specific material according to the type of cable.


This technology requires no heating source, no material filling or wrapping. Installation is done by removal of the tubes. Joints can be energized once assembly is finished.
