Overview:
The 35kV high-voltage cable distribution box with switch is a supporting equipment for the urban grid cableization transformation. It can be installed outdoors, indoors, or buried underground. It can connect power cables with box transformers, load switch cabinets, negative one fuse combination electrical cabinets, ring network power supply units, etc., playing the role of tapping, branching, relaying, or conversion, providing great convenience for cable networking.
The DFW-35/630 series, featuring a high-voltage switch cable distribution box and an environmentally friendly outdoor cable distribution box with high-voltage live display, is a relatively comprehensive high-voltage equipment in China, filling the gap for 35KV (40.5KV) high-voltage switch cable distribution boxes. It is suitable for use in AC 50Hz 35KV (40.5KV) transmission and distribution electrical lines. As a new structure of outdoor ring main switchgear, it can be installed and used within 35KV prefabricated box-type substations. As the main equipment for ring main and switching stations, it is primarily used in industrial parks, residential areas, commercial centers, mining areas, airports, railways, port areas, power stations, and other distribution networks. It is suitable for urban power grid renovation projects, significantly reducing outgoing cables and footprint, and improving power supply reliability.
This tap-off box meets the requirements of standards such as GB3906 and IEC298, and features reliable "five-prevention" functions. It is a high-voltage power distribution device.
