0.6/1kV Power Cables with Concentric Neutral
- It is suitable for power transmission in AC rated voltage power lines of 0.6/1kV and below;
- The long-term allowable operating temperature for cross-linked polyethylene insulated conductors is 90℃, and for PVC insulated conductors is 70℃. In case of short circuit (maximum duration not exceeding 5 seconds), the maximum temperature for cross-linked polyethylene insulated conductors is 250℃, and for PVC insulated conductors is 160℃;
- The ambient temperature during cable laying should not be below 0℃. If it is below 0℃, preheating is required;
- The minimum bending radius for multi-core armored cables is 12 times the cable outer diameter, and for unarmored cables is 15 times;
