Heat-Shrinkable Cable Accessories

Heat-Shrinkable Cable Accessories

Heat-Shrinkable Cable Accessories are essential components for insulating, sealing, and protecting cable splices, terminations, and repairs across electrical power systems. These accessories are manufactured from radiation-cross-linked polyolefin or elastomeric materials that, when heated, contract radially to form a tight, conformal seal around cables and connectors. The shrinking process is triggered by applying controlled heat (via torches or hot air tools), allowing the material to encapsulate irregular shapes and create a barrier against moisture, chemicals, abrasion, and electrical stress. Designed for medium and low-voltage applications, these accessories restore cable integrity and ensure long-term reliability in diverse environments, from underground installations to industrial settings.

Ideal for utilities, telecommunications, and industrial maintenance, heat-shrink accessories offer a versatile and efficient solution for cable management. Their design often includes integrated elements such as adhesive liners that melt during heating to provide environmental sealing, and stress control layers to manage electrical field distribution at terminations. These accessories are available in various forms: tubes, caps, breakouts, and full kits for splices and terminations. They excel in harsh conditions due to their UV resistance, flame retardancy, and operational temperature range (-55°C to +125°C), making them suitable for outdoor, submerged, or corrosive environments.
