succeeded in developing an ultra-compact 123/145kV model. Developing three-phase common-enclosure switchgear involves three major considerations: coordination of interphase insulation, minimization of interphase electromagnetic stress, and maximization of current capacity. Coordinating insulation between phases requires a
ontal circuit-breaker module provides optimal performance and low main-tenance. ELK-04 C circuit-breakers are equipped with . uto-pufferTM interrupters, i.e. self-blast interrupters with one unit per pol. . They require minimum maintenance and only a low amount of operational energy. The optimized and compac. layout minimiz.
