120V High Voltage Cable Heating Blankets 0-90ºC

Professional Heating Jackets for High Voltage Cable Straightening & Jointing

Our 120V High Voltage Cable Heating Blankets are specifically designed for the power transmission, utility and renewable energy industries, providing a safe, efficient and reliable solution for straightening, relaxing and conditioning high voltage cables before installation and jointing.

Suitable for both high voltage (HV) and extra high voltage (EHV) power cables, these specialist heating jackets deliver controlled, even heat to remove cable memory, increase flexibility and make cable handling significantly easier during installation. They are particularly effective when preparing cables for jointing, termination and the post-curing of epoxy joints.

Each heating blanket features an integrated PT100 temperature sensor, connected to a detachable digital temperature controller that provides precise temperature regulation and a clear digital temperature display. This ensures consistent heating performance whilst helping to protect valuable cables from excessive temperatures.

Manufactured from durable silicone-impregnated cloth with high-quality fibreglass insulation, these heating blankets are built to withstand demanding site conditions while delivering excellent thermal efficiency. A wide range of standard lengths is available, and multiple heating blankets can be combined to accommodate different cable diameters. Bespoke sizes can also be manufactured to suit specific project requirements.
