Pre-branched cable

Pre-branch cable is to prepare the branch cable in advance. The cable can be used directly after leaving the factory. It does not need to branch on site. The one-time power-on rate is high to avoid various hidden dangers on site. Anti-seismic, air-tight, waterproof and fire-resistant. Pre-branched cable is the cable that the factory prefabricated branch line according to the user's design drawing when producing the main cable. It is a new technology product in recent years. Compared with the original technology, it has excellent anti-seismic, air-tight and waterproof properties. The construction period is greatly shortened, the material cost and construction cost are greatly reduced, and the reliability of power distribution is greatly guaranteed

Pre-branch cable classification

The pre-branch cable is composed of four parts: 1. trunk cable; 2. Branch line; 3 Branch connector: 4 relevant accessories, and has three types: common type, flame retardant type (ZR) and fire resistant type (NH). Pre-branched cable is an alternative product of bus duct power supply in high-rise buildings. It has the advantages of reliable power supply, convenient installation, good waterproof, small floor area, low failure rate, low price, and maintenance-free. It is suitable for distribution lines with AC rated voltage of 0.6/1KV. It is widely used for vertical power supply in the electrical shaft of high and middle storey buildings, residential buildings, commercial buildings, hotels and hospitals, as well as for power supply systems such as tunnels, airports, bridges and highways.

Advantages of pre-branched cable

1. Excellent seismic resistance, air tightness, water resistance and fire resistance; 2. The main cable conductor has no joint and good continuity, reducing the probability of failure; 3. Adopt advanced fully mechanized crimping technology to avoid the influence of human factors; 4. With high customization, the branch position can be set according to the needs of the distribution points of the distribution system; 5. The contact resistance of the branch is very small, which is not affected by thermal expansion and contraction; 6. Reduce power distribution cost and project cost, with high economic indicators and obvious comprehensive benefits; 7. Simple installation, short construction period, greatly reducing installation time compared with enclosed bus duct; 8. It is maintenance-free after installation and operation, and no maintenance is required at ordinary times.
