1. The panel is novel and complete function, not only with fixed panel isolate live busbar feature, but also convenient for
maintenance, easily to exchange circuit breaker, thereby assure of maintaining safely and conveniently, meanwhile, choose
primary plug in contact.
2. Main switch is miniaturization vacuum circuit breaker(introduce advanced technology). Choose large creeping distance porcelain
enclosure vacuum arc extinction chamber, adopt air insulation. It suitable for rural net work reconstruction and industrial
enterprise specially, equipped with miniaturization disconnect switch, double functions for main knife switch and earthing switch,
