Abstract
A single-pole gas-insulated line duct has a enclosing tube and an inner conductor held centered in place in the enclosing tube by support insulators. Electrode bodies embedded in arms of the support insulators engage either in a slot between flanges of sections of the enclosing tube or lie against the inside wall of the sections with a spring-action contact member. Locking members connect the support insulators and sections of the inner conductor. Coupling members can be introduced into abutting sections of the inner conductor and demonstrate mutli-surface sliding contact elements.
