Cable Heating Blankets For Straightening High Voltage Cables.

 

HV 66kV 132kV 275kV 400kV

Hemi Heating AB have developed a standard range of cable heating jackets for straightening and relaxation of high voltage cables. Cable heating jackets are used to straighten extra high voltage and high voltage (EHV-HV) power and submarine cables in the power utility and renewable energy sectors.

Cable heating blankets enable the straightening of HV cable prior to jointing and terminating by the cable jointers - typically the cable blanket would enable the heating of 132kV-400kV cable prior to the installation of Tyco, ABB Kabeldon, Pfisterer or Prysmian cable joints.

Cable heating jackets are delivered together with a control box containing an PID-temperature control with dual LED display showing setpoint and actual temperature.
