90 degree 4-core flame retardant cable
Flame retardant cable introduction
The method generally used for flame-retardant cables is to add halogen-containing halides and metal oxides to materials such as insulation, sheath and filling. Evaluation from the perspective of flame retardancy is an excellent method.
Application scope:
Polyvinyl chloride insulated power cables are suitable for fixing in AC 50HZ, rated voltage 0.6/1kV transmission and distribution lines.
XLPE insulated power cables have many advantages compared with paper insulated and PVC insulated cables. Cross-linked polyethylene cables have high electrical properties, mechanical properties, thermal aging properties, environmental stress cracking resistance, chemical corrosion resistance, simple structure, easy use, and are not limited by large layer differences. Can be used for a long time at 90 degrees high temperature

Technical performance:
1. The maximum temperature of long-term work: ≤90°C
2. Installation temperature: ≥0°C
3. The highest short-circuit temperature (no more than 5 seconds): 250°C
4. In the case of insufficient mechanical tension, it cannot be laid without falling. Single-core cables cannot be fixed with iron laying pipes or round iron tools around the cable
