◆ Rated voltage: 6kV, 10kV;
◆ When laying, the minimum bending radius of the cable is 20 times the cable diameter;
◆ The long-term allowable working temperature of the cable conductor is 90℃;
◆ The maximum temperature of the cable conductor during short-circuit (the longest time is 5s) does not exceed 250°C.

◆ The protective box used for the 110KV～220KV cross-linked cable line sheath insulation protection device is connected with the transposition box. It is used for grounding connections in the transmission and distribution line and the cross interconnection box. The connection method of the inner and outer conductors of the coaxial cable is reasonable, convenient, and reliable in use.
