Description

Busbar heat shrink tubing is a protective material used for busbar and cable connections in power systems. It is made of thermally shrinkable polyolefin materials that can shrink and tightly encapsulate the surface of busbars or cables when heated, providing insulation and protection. Busbar heat shrink sleeving has excellent insulating properties and can effectively prevent electrical leakage and short circuits in electrical equipment. It is easy to install, requiring only a heat gun or similar tool to heat and quickly shrink and secure onto busbars or cables.

Volsun 10KV bus bar heat-shrinkable tube are perfect for insulation protection of copper busbar in electrical cabinets. They main include feature UV resistance, tear resistance, and aging resistance, ensuring long-lasting performance and safety. 

Various sizes and colors are available to meet customer requirements, ensuring optimal protection and performance.
