The flexible conductor is cut off because it has two cylindrical magnetic shield members with their free ends facing each other at an appropriate interval and a bellows connecting the respective free ends of the two cylindrical magnetic shield members. Even if it is possible, the flexible conductor is always held by the magnetic shield member to prevent discharge, mutual short-circuit, opposite ground, etc. between the electric devices, and to disassemble the SF 6 gas inside the power receiving and transforming equipment. To prevent the insulation function from being impaired.
