Patent ID: 8111503

Claim:
A gas-insulated switchgear comprising: first and second main buses disposed in parallel; first, second, and third horizontal-type circuit breakers that are disposed as being aligned in a direction of axis lines of both the main buses so as to each have an axis line mutually orthogonal to the direction of the axis lines of both the main buses, the circuit breakers electrically connecting both the main buses together in series and also each having a pair of disconnect switches attached at both sides; first and second branch lines, the first branch line being drawn from a portion between the first circuit breaker and the second circuit breaker, and the second branch line being drawn from a portion between the second circuit breaker and the third circuit breaker; and first and second cable heads connected to the first and second branch lines, respectively, wherein the first and second cable heads are disposed so that a center of the first cable head and a center of the second cable head are positioned on a straight line orthogonal to the direction of the axis lines of both the main buses in a planar view.
