Non-excitation Cage Form Tap Changer

WSL2-63/10-4X3

Part number: WSL2-63/10-4*3, means 63A/ 10KV/ 3positions/ 3phase, and central part voltage regulation.

The cage non excitation tap changer for transformers has horisental type, vertical type and bell type three installations. The lid below the black metal casting has been re-designed for machining plate structural parts, treat the surface black, remove the casting of transformer oil pollution. Usually applied to frequency of 50Hz, 60Hz, rated voltage 10KV~66KV, rated current 63A~630A three-phase, single-phase oil-immersed transformers. The voltage regulator parts are terminal part, central part, neutral part, double-bridge crossing connection and Y- triangle conversion, changed under the non-excition condition.
