11KV and 33 KV double break isolators are mechanical switching accessories installed either vertically or horizontally in the open position in the overhead lines to generate an isolating distance for electrical safety purposes. These IS-certified substation fittings and pole line fittings have galvanized coated surfaces to resist harsh weather. Available in 200/400/630 Amp voltage choices, these high voltage isolators are useful for breaking electrical circuits. The triple pole construction-based design of this product range includes galvanized steel base, fixed and movable type copper contacts, post-type insulators, and galvanized iron-made coupling pipes. To suit specific application requirements, this product range is available in porcelain and polymer-made versions.
