Use electrical copper conductor, 90℃ cross-linked polyethylene insulation, and PVC outer sheath.

Use characteristics:
1. The maximum rated temperature of the cable conductor is 90℃
2. During short circuit (the longest duration does not exceed 5s), the maximum temperature of the cable conductor does not exceed 250°C.
3. The ambient temperature when laying cables should not be lower than 0℃.
4. Minimum bending radius during installation: single-core cables are not less than 20 times the outer diameter of the cable, and multi-core cables are not less than 15 times the outer diameter of the cable. The minimum bending radius of the cable near the connection box and the terminal (bending should be carefully controlled, such as using a forming guide plate) single-core cables shall not be less than 15 times the outer diameter of the cable, and multi-core cables shall not be less than 12 times the outer diameter of the cable.
