Silicone Cold Shrink Tubes are a type of cold shrink tube made of silicone rubber, which is widely used in cable insulation, protection and repair. Silicone rubber has excellent high and low temperature resistance, electrical insulation performance and weather resistance, making this type of cold shrink tube particularly suitable for cable protection in high and low temperature and harsh outdoor environments.

Material Properties:
High and low temperature resistance: Silicone rubber can work stably in the temperature range of -60°C to +60°C, suitable for extreme temperature environments.
Excellent electrical insulation performance: Provides reliable electrical insulation, suitable for medium and high voltage power systems.
Strong weather resistance: UV and ozone resistant, suitable for long-term outdoor use.
Soft and elastic: Silicone rubber has good elasticity and recovery properties, and can tightly wrap the cable.
Chemical corrosion resistance: Good tolerance to most chemicals and solvents.
Cold shrink technology: No heating is required. When installing, just pull out the internal support core to automatically shrink and tightly wrap the cable. Easy installation, suitable for on-site operation.
Mechanical properties: Provides good tensile, compressive and impact resistance, protecting the cable from mechanical damage.
Waterproof and moisture-proof: Tightly wrap the cable to effectively prevent water and moisture intrusion.
