230V High Voltage Cable Heating Blankets 0-90ºC

Professional Heating Jackets for High Voltage Cable Straightening & Jointing

Our 230V High Voltage Cable Heating Blankets are specifically engineered for the power transmission, utilities and renewable energy sectors, providing a safe and effective solution for straightening, relaxing and conditioning high voltage power cables prior to installation and jointing.

Designed for use on high voltage (HV) and extra high voltage (EHV) cables, these specialist heating jackets deliver controlled, uniform heat to help remove cable memory, improve flexibility and simplify cable handling during installation. They are particularly effective when preparing cables for jointing, termination and post-curing of epoxy joints.

Each heating blanket incorporates an integrated PT100 temperature sensor, which works alongside a detachable digital temperature controller to provide accurate temperature regulation and continuous digital temperature monitoring. This ensures consistent heating performance whilst protecting valuable cable assets from overheating.

Manufactured from robust silicone-impregnated cloth with fibreglass insulation, these heating blankets are designed to withstand demanding site conditions while delivering excellent thermal efficiency. Available in a variety of standard lengths, they can also be combined to accommodate different cable diameters or manufactured to bespoke dimensions for specialist applications.
