Cable accessories are an indispensable part of the cable line, and they are also the thinnest link in the entire line; 2. The quality of the cable accessories has important implications for the safe operation of all cable lines; 3. The installation and manufacture of cable accessories At the same time, it does not damage the original insulation, sealing and shielding of the cable; 4. The function of the cable accessories is to restore the original conductive core of the cable, restore the functions of insulation, shielding, and shutdown protection. |
What is the importance of cold shrinkable cable accessories in cable lines?
1. Cable accessories are an indispensable part of the cable line, and they are also the thinnest link in the entire line;
2. The quality of the cable accessories has important implications for the safe operation of all cable lines;
3. The installation and manufacture of cable accessories At the same time, it does not damage the original insulation, sealing and shielding of the cable;
4. The function of the cable accessories is to restore the original conductive core of the cable, restore the functions of insulation, shielding, and shutdown protection.
Basic requirements for cold shrink cable accessories:
1. Good electrical conductivity, reliable insulation, high enough mechanical strength, good sealing performance, excellent anti-corrosion, flame retardant and thermal performance;
2. The main requirements are that the connection resistance is small and the connection is stable, and can withstand the impact of the fault current;
3. After long-term operation, its touch resistance should not be greater than 1.2 times of the resistance food of the same length of the cable core body;
4. It should have certain mechanical strength, vibration resistance and corrosion resistance.
