IP33 IK10 High Voltage Cable Branch Cabinet Ring Net Inflatable Medium Voltage Products
Overview of XGW-12 ring net box opening and closing station
It adopts prefabricated electrified and touchable silicone rubber cable head, fully sealed, gold insulated, and rabbit maintenance, which can reliably ensure personal safety: compact structure, small and beautiful appearance, stainless steel double-layer cabinet; realizing area without affecting the operation of the main network Power failure inspection and repair, reduce the power failure range; can be equipped with one or more SF6 load switches. The wiring method is flexible and diverse, and the branch outgoing line can reach 8 circuits; lightning arrester, short-circuit fault indicator, current-limiting fuse, etc. can be selected to meet various requirements of users.
It is widely used in Chengdian densely populated areas such as urban power grid transformation, residential quarters, and commercial centers.
