◆ 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 cable conductor ：90℃;

◆ In case of short circuit (the longest time is 5s), the maximum temperature of cable conductor shall not exceed 250℃.

◆ The protection box for 110KV~220KV cross-linked cable line sheath insulation protection device is connected with the transposition box. Grounding connection is used in transmission and distribution lines, and connection is used in cross-interconnection boxes. The connection mode of inner and outer conductors of coaxial cable is reasonable, convenient and reliable.
