Cold shrink cable accessories, such as terminations and joints, are widely concerned as sealing, insulation, and stress control in electrical connections. Regarding to heat shrink systems that require flame or heat tools, cold shrink accessories use pre-expanded material on a removable core. When the core is pulled, the material shrinks quickly to form a tight seal, enabling fast, easy, and safe installation. The way to selecting the correct accessory is depending on the cable’s insulation material. XLPE cables are common in medium/high-voltage applications silicone rubber. based accessories are used, offering compatible dielectric performance and solid interface formation. EPR insulated cables can also use silicone cold shrink accessories, provided electrical and dimensional ratings match. Older paper-insulated, lead-sheathed (PILC) cables, specialized transition kits are necessary to seal the lead sheath and bridge the dielectric transition to modern materials.

When selecting cold shrink cable accessories, it's crucial to match the internal connector to the cable conductor material.Copper conductors require connectors with high clamping force to ensure a stable connection.Aluminum conductors (which are softer and more susceptible to oxidation) require specialized alloy connectors with oxidation resistance or a serrated surface.When selecting cold shrink cable accessories, verify the conductor material compatibility on the accessory datasheet to ensure a safe and reliable installation.
