Overview
It adopts prefabricated live-touchable silicone rubber cable heads, fully sealed, fully insulated, maintenance-free, reliably ensuring personal safety; compact structure, small and elegant appearance, stainless steel double-layer enclosure, service life of over twenty years; on the premise of not affecting the operation of the main network, it enables regional power outage maintenance, reducing the scope of power outage; it can be equipped with one or more SF6 load switches. Wiring methods are flexible and diverse, with branch outgoing lines up to eight circuits; optional surge arresters, short-circuit fault indicators, current-limiting fuses, etc., to meet various user requirements.
