Cable terminal with connection for cooling water - for high voltage, high power cables for gas insulated metal clad switchgear has two parts enclosed in metal jacket

摘要

The cooling water is brought from conductor potential to earth potential. The cable terminal is divided in two functional parts, each enclosed in its own, pref, tubular metal jacket (7, 11) which forms an extension or a branch of the tubular switch gear casing (14) with which it shares the insulating gas atmosphere part consists of an insulator, a voltage controlled stress core of the cable core and terminal fittings (6) with terminals and a cooling water pipe (8) passing through itthe second part consists of a flanged insulating pipe for the cooling water, and terminal fittings (10) into which the water pipe (8) emerging from the first part is inserted for its connection with the insulating pipe.
