I. Overview

The 35kV high-voltage cable distribution box with switch is a supporting equipment for the transformation of urban network cables. It can be installed outdoors, indoors or buried in places. It can connect power cables to box-type transformers, load switch cabinets, and negative fusion combined electrical appliances. Cabinets, ring network power supply units, etc. are connected to play the role of tap, branch, relay or conversion, providing great convenience for cable networking.

 2. Main features

Using prefabricated cable plug-in devices, it has the excellent performance of fully insulated, fully sealed, fully waterproof, maintenance-free, safe and reliable. Cable connectors have various varieties and complete specifications in series: rated current: 200A, 400A, 630A, 1000A, 1250A; rated voltage: 35kV level.

DFW-35/630 series, with high-voltage switch cable distribution box, high-voltage live display environmentally friendly outdoor cable distribution box, is the most advanced high-voltage equipment in China, making up for the 35KV (40.5KV) with high-voltage switch cable distribution box Blank, suitable for AC 50Hz 35KV (40.5KV) transmission and distribution electrical lines. It is a brand-new structure of outdoor ring network switch equipment, and can be installed and used in 35KV prefabricated box-type substations. It serves as a ring network and switchgear. The main equipment of closed stations is mainly used in distribution networks such as industrial parks, residential areas, commercial centers, mining areas, airports, railways, ports, and power stations. It is especially suitable for urban power grid transformation projects, greatly reducing outgoing cables and floor space, and improving Power supply reliability.

This branch box can meet the requirements of GB3906, IEC298 and other standards, and has reliable "five prevention" functions. It is a high-voltage power distribution equipment with superior performance.
