35KV High Voltage Outdoor Cable Distribution Box
In recent years, cable branch box has been widely used in cable engineering equipment in power distribution network system. Its main characteristics are two-way door opening, the use of insulation through the wall sleeve as the connection busbar, with small length, clear cable arrangement, three-core cable does not need to cross large span and other remarkable advantages. Generally, the rated current is 630A and the cable joint is fixed with bolts. To a variety of different user requirements can provide satisfactory technical solutions.
