Cable branch box
Cable branch box classification  European cable branch box. The cable branching box is a cable engineering equipment widely used in power distribution systems in recent years. Its main feature is that the door is opened in two directions, and the insulated wall bushing is used as the connecting busbar. The utility model has the advantages of small length, clear cable arrangement, and three-core cable without large span crossing. Generally, the rated current 630A bolted connection cable connector can provide a satisfactory technical solution for various user requirements.
 American cable branch box. The cable branching box is a busbar type horizontally arranged cable branching device, which is widely used in cable engineering equipment in cable distribution systems. It opens in one direction and the horizontal multi-pass busbar is the main feature. It has the advantages of small width, flexible combination, full insulation and full sealing. According to the current carrying capacity classification, it can be generally divided into two types: 630A main circuit and 200A branch circuit. The connection and combination method is simple, convenient and flexible, which can greatly save equipment and cable investment, improve power supply reliability, and is suitable for commercial centers, industrial parks and urban dense areas. It is an ideal product for urban power grid transformation.
    Switch cable branch box . The switch cable branch box is widely used in power systems because of its full insulation, full sealing, corrosion resistance, maintenance-free, safe and reliable, small size, compact structure, simple and convenient installation, and flexibility. The switch adopts TPS series products with visual fractures imported from Italy, and the SF6 gas with advanced arc-extinguishing characteristics is used as insulation and arc extinguishing medium. Its good insulation properties, extremely short arcing time, visible fracture window, resistance The corroded stainless steel casing makes the performance of the cable branch box excellently displayed, fully satisfying the full insulation, full sealing, high reliability, oil-free, multi-combination and maintenance-free of the power distribution users. Modular, corrosion resistant, etc.
The role of the cable branch box 1. There are many small-area cables on a long distance line, which will cause the cable to be wasted. Therefore, in the line-to-power load, the trunk cable is often used, and then when the load is approaching. The cable trunking box is used to divide the trunk cable into several small-area cables, and the small-area cable is connected to the load.
2, on a long line, the length of the cable can not meet the requirements of the line, then you must use cable joints or cable transfer box, usually the cable intermediate joints in short distance, but when the line is relatively long, according to experience For cable lines above 1000m, if there are many intermediate connectors in the middle of the cable, in order to ensure safety, the cable branch box will be considered for transfer.
