<p>PROBLEM TO BE SOLVED: To provide a gas insulation switch which is easy to install with a small installation space and manufactured at a low cost. SOLUTION: Connection bushes 2a, 2b, and 2c are inserted in the respective bushing cases 7a, 7b, and 7c that are joined by connection bus bars 6a, 6b and a gas insulation switch(GIS) connection bus bar 3. An iron frame 11 crossing over the connection bus bar 6a, and an iron frame 12 crossing over the GIS connection bus bar 3 are provided. The iron frame 11 has beams 11a and 11b on its upper and lower positions. The iron frame 12 has a beam 12a in a position higher than the beam 11b. Insulators 400, 401d, insulators 401a to 401c, and insulation 402 are put among these beams 11a, 11b, and 12a. Then, overhead wires 5a, 5b, and 5c are supported firmly by the insulators 400, 401d, the insulators 401a to 401d, and the insulator 402, and connected to the bushings 2a, 2b, and 2c.</p> |
