Nexans Siwo-kul high voltage cables

The connection cable Type SIWO-KUL™ is a very flexible single core cable. 
It is manufactured in the voltage range of 1.1 kV, 3.3-4.2 kV, 6.6-7.2 kV and 13.8-15.0 kV.


The SIWO-KUL™ cable is used where high flexibility is required and high temperature conditions are present.

It is therefore a suitable connection cable for high voltage machines like:

  • Transformers
  • Motors
  • Generators, etc.

The operating temperature for continuous service extends from –55°C up to 180°C.


  • Copper conductor tinned, flexible IEC 60228, class 5
  • Tape (up 16 mm2), Semi-conductive layer (only for 6.6 and 13.8 kV)
  • Silicone rubber insulation
  • Separator tape
  • Protective synthetic yarn braiding, varnished
