Support OEM/ODM Silicone Rubber Cold Shrink End Caps
- Detailed

Volsun silicone cold shrink end cap is made from high-quality silicone rubber material and is pre-expanded on a support tube made of strip plastic. This type of cap is easy to install in the field without the need for heating; simply slip the cap over the end of the cable and remove the support strip. The inherent excellent elastic memory function of the silicone rubber allows the cap to form a stable and lasting insulating seal at the end of the cable after it has shrunk into place. This characteristic makes the cold-shrink cap particularly suitable for use in the storage and on-site construction areas of low and high-voltage cables, enabling rapid insulation sealing and meeting the needs for cable insulation, on-site construction, and moisture and water resistance in storage.
