Electrical cables are crucial for modern infrastructure but their connections are weak spots. Heat shrink accessories protect against moisture, corrosion, and electrical issues.

Choosing the right heat shrink accessories mainly depends on the cable's insulation material, which keeps the electrical current within the conductor. The key is to make sure the accessory's shrink temperature is lower than the cable insulation's melting or deformation point.Common cable insulation materials include PVC，XLPE /EPR and Silicone rubber.

Heat shrink tubes come in materials like polyolefin, neoprene, or fluoropolymers, each with its own shrink temperature. Make sure the adhesive’s activation temperature is safe for your cable insulation.
