Product description•It adopts prefabricated electrified and touchable silicone rubber cable head, which is fully sealed, fully insulated, maintenance-free, and reliable to ensure personal safety.
•Compact structure, small and beautiful appearance, stainless steel cabinet, service life up to more than 20 years.
•Under the premise of not affecting the operation of the main network, realize regional power outage maintenance and reduce the scope of power outages.
•It can be equipped with one or more SF6 load switches.The wiring method is flexible and diverse, the branch outgoing line can reach 8 loops at most.
•Optional lightning arrester, short-circuit fault indicator, current-limiting fuse, etc., to meet various requirements of users.
Main new advantages● Small size, compact structure, easy to install and operate
● Stainless steel or metal steel board ,which thickness ≥ 2mm
● Anti-corrosion & with special Spray-painting artworks
● Usage life more than 30 years.
● It can be used in some harsh environments like high or lower temerature ,some dust area
● Fully sealed structure,without insulation distance
● High voltage electric parts with cable connector or use silicon rubber for people safety.
● With zno arrester
● Its cables can be splitted into be 7 branches to work together with SF6 loading switches to reach net power-supplying.
● The cable connector can be used as switch, it can be on or off with loading. The max on-off voltage can reach 200Amp.
● After fix the fault indicator, user can test circuit fault very quickly
● Cheaper cost ,save cable
●Cable connectors comply with IEEE386 standard,all cables are suitable for crosslinking polyethylene insulated cables.
