Product Description
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.
35kv cable branch box features:
1, outdoor type (and indoor type), fully sealed structure, "five prevention" safety, maintenance-free, reliable personal safety guarantee.
2, high voltage live display environmental protection type outdoor cable branch box, simplify the city cable network system, save investment.
3, outdoor type, dustproof, moisture-proof, flood resistance, corrosion resistance, strong environmental adaptability, flexible combination, from one way into the wire outlet to multiple, can meet various wiring requirements.
4. Small size, compact structure, beautiful appearance, simple installation, convenient operation mode conversion, flexible protection setting. And a live display, with short circuit indicator, with lightning arrester.
5, small area, low height, beautiful appearance, can be coordinated with the surrounding environment, wiring scheme is flexible and diverse, installation operation is very convenient.
