What are cold shrink cable accessories?

Cold contraction cable accessory is a kind of prefabricated cable accessory that can be constructed at room temperature without heating. Cold shrink power cable accessories are made of imported liquid silicone rubber. After installation, they always maintain an appropriate radial pressure on the cable body. The interface features are good, no power leakage due to cable operation. The stress control part is integrated with the main insulation, which effectively solves the problem of electric stress concentration in the outer shielding section of the cable and ensures reliable insulation. It is a very important cable accessory. Several structural methods and parameter control methods are generally adopted to deal with the electrical stress concentration in cold contraction cable accessories. Stress cone and other structural methods are better than parameter control products to alleviate electric field aggregation and distribution.

What are the requirements for cold shrink cable accessories

1. Good electrical conductivity, reliable insulation, high enough mechanical strength, good sealing function, anti-corrosion and flame retardant, excellent thermal performance.

2. The main requirements are small connection resistance, stable connection, can withstand the impact of fault current.

3. After long-term use, the contact resistance should not be greater than 1.2 times of the resistance of the cable core of the same length.

4. It should have certain mechanical strength, vibration resistance and corrosion resistance.

What are the roles of cold contraction cable accessories?

1. cable accessories are an indispensable part of the cable circuit, together is also the thinnest link in all circuits;

2. The quality of cable accessories is of great significance for the safe operation of all cable lines;

3. During the installation and manufacture of cable accessories, the original insulation, sealing and shielding of the cable shall not be damaged;

4. The function of the cable accessory is the original conductive core of the rehabilitation cable, which has the functions of rehabilitation insulation, shielding, shutdown protection and so on.

There are many kinds of cold shrinkage cable accessories available on the market. If you are looking for a good quality and reasonable price of Cold Shrinkable Accessories,Haivo Electrical Co.,Ltd  can  provide you with the best.
