Cable Heating Blankets & Jackets for Cable Straightening

PFISTERER range of Cable Heaters & Cable Straighteners are used to provide electric surface heating to the cable outersheath and XLPE insulation of medium/high voltage power cables prior to the installation of Joints, Terminations & Connectors– this includes the PFISTERER CONNEX range of inner cone plug cable terminations for connecting MV HV power cables with polymeric insulation into bushings located on gas insulated switchgear.

The cable heaters, manufactured by PFISTERER, are simply placed around the cable, wrapped and strapped using adjustable side tethers, to position the heater into direct contact with the outer sheath of the MV HV cable – the cable heaters are used in conjunction with 2 metre length aluminium cable straightening rails (weight 9.5kg). Manufactured from high quality protective materials the cable heater jacket provides durable performance in onshore and offshore cable trench, tower and substation locations.

The cable heaters are typically used to heat polymeric type XLPE insulated cables: 33kV 66kV 132kV.

Polymeric XLPE cables have a tendency to bend – this can give rise to problems associated with the fitting of medium/high voltage cable terminations, connectors or straight joints. The cable heating jackets provide a solution to the need for a heat treatment process to be applied to each cable core to relieve the mechanical stresses that are locked into the cable insulation – this eliminates the behaviour inclination of the cable to recoil as the heat allows physical cable manipulation and straightening by the HV Jointer.
