You can choose TAILI as your supplier in China, and purchase our high quality cold shrink cable accessories, which are a type of power accessory that does not require heating and relies on the inherent elasticity of the material to tightly wrap around the cable at room temperature, achieving insulation, sealing, and stress control. They are usually made from pre-expanded materials such as silicone rubber or ethylene propylene diene monomer (EPDM) rubber.
During installation, the internal support strips are removed and the accessory reliably retracts and fixes itself due to its elasticity. They are widely used in the terminations and intermediate connections of power cables, featuring quick installation, reliable performance, and good weather resistance.
1. Installation is simple and fast: No heating required, construction at room temperature, significantly shortening the construction period.
2. Excellent performance: Good insulation performance, sealing ability, weather resistance, and anti-aging properties.
3. Strong adaptability: Can expand and contract with the cable, suitable for various environments.
4. Small size: Compact structure, occupies little space.
5. High reliability: After installation, the internal interface pressure is stable, and there is little risk of delamination.
1. Presence of flammable gas or flammable environment: Cold shrink installation does not require open flames, avoiding fire risks and eliminating the need for a hot work permit.
2. Damp or humid environment: Cold shrink accessories provide excellent waterproof and moisture-proof sealing, suitable for damp environments such as underground and underwater.
3. Large cable load or temperature fluctuations: The "active memory" feature of cold shrink allows the cable to expand and contract during operation, maintaining a tight seal, while heat shrink products may fail due to rigidity.
4. Limited space or difficult installation: Cold shrink accessories are small in size and easy to install, particularly suitable for narrow spaces.
5. Requires fast installation speed: No heating required, fast installation, shortens construction period and improves efficiency.
6. High requirements for weather resistance: Silicone rubber, EPDM rubber and other materials have good resistance to ultraviolet rays and wear, suitable for outdoor, railway and direct burial environments.
7. Medium and low voltage power distribution networks and cable heads, intermediate joints: Widely used in various voltage levels of cable terminals and intermediate connections.
