<p>An improved mounting support construction characterized by an arc-extinguishing puffer-unit at the upper end of each of the slanted arms, or generally-"V"-shaped supporting structure, with an additional third puffer-unit interposed, interconnecting, generally-horizontally-arranged, gas-sealed bridging center casing structure. Thus, a generally-inverted "A"-type of mounting support arrangement is provided viewed in an inverted relationship by an observer the three series puffer-units are disposed at the lower ends and in the horizontal bridging leg of the inverted "A"-shaped structure. A typical voltage rating would be 420 K.V., for example.</p> |
