Details of accessories for Cold shrink cable accessories

Cold shrink cable accessories (power cable accessories) Product details:

1. The complete set of products adopts full cold shrinkage technology, without the need for hot work or tools. During installation, you can simply pull out the wire core, and the elastic body will quickly shrink and tightly adhere to the required installation site.

2. Reliable silicone rubber with excellent insulation and high elasticity. After installation, it always maintains appropriate radial pressure on the cable body, making the inner interface tightly bonded and preventing electrical breakdown due to the breathing effect during cable operation. The stress control part is integrated with the main insulation, effectively solving the problem of electrical stress concentration at the outer shielding surface of the cable, ensuring reliable insulation and safe operation.

3. Products that easy to intall have been manufactured and formed in the factory. No special training is required, the installation and operation are simple, and there is no need for fire, saving time and effort. The fully cold shrink automatic reset technology makes installation easy without sweating, greatly reducing quality accidents caused by improper operation, and solving the problem of prefabricated cable accessories not contracting tightly or not fitting in.

4. Widely used for pollution prevention, aging resistance, good hydrophobicity, and excellent cold and heat resistance, especially suitable for high-altitude areas, cold areas, humid areas, salt spray areas, and heavily polluted areas. And no open flames are used during installation, especially suitable for flammable and explosive places such as petroleum, chemical, mining, tunnels, etc.

5. The equipment has excellent quality, high degree of automation, and reliable performance.

6. With extended cold shrink tubing and no seam lines, it have a beautiful appearance.
