Enclosed switchgears.

摘要

Buses in gas-filled cubicles combined into a switchgear array are connected together by use of T-shaped connectors (36A, 36B, 36C) provided outside of the cubicles and short straight insulated cables (39) of a single conductor type thereby eliminating the necessity of opening any part of the gas-filled cubicles when the switchgear array is disassembled, for instance, for transportation. The T-shaped connector (36A, 36B or 36C) comprises a T-shaped bushing (42), shielding conductor (42b) and a rod-shaped conductor (42c), both formed integrally with the bushing (42) for connecting the conductor (39a) of the cable (39) with one of the buses (30), a stress cone (47) inserted between the outer surface of the insulated cable (39) and the bushing (42), and various means (49, 49a, 49b) for forcing the stress cone (47) into the inserted position.
