Pre-branch cable composition:
1. Main cable; 2. Branch line; 3. Branch joint: 4. Related accessories, with three types: ordinary type, flame retardant type (ZR), and fire-resistant type (NH). Pre-branched cables are a substitute for busbar trunking in high-rise buildings, offering advantages such as reliable power supply, easy installation, excellent waterproofing, small footprint, low failure rate, affordable price, and maintenance-free operation. They are suitable for AC rated voltage of 0.6/1KV distribution lines. Widely used for vertical power supply in electrical shafts of high-rise buildings, residential buildings, shopping malls, hotels, and hospitals, they are also suitable for power supply systems in tunnels, airports, bridges, highways, etc.

Product features:
1. Excellent seismic resistance, airtightness, waterproofing, and fire resistance
2. The main cable conductor has no joints, ensuring good continuity and reducing the probability of faults.
3. Advanced fully mechanized crimping technology is adopted to avoid the influence of human factors.
4. High customizability, allowing the setting of branch positions according to the needs of distribution points in the power distribution system.
5. The branch contact resistance is extremely small and unaffected by thermal expansion and contraction.
6. Reduce power distribution costs and project costs, with high economic indicators and significant comprehensive benefits.
7. Easy to install with a short construction period, significantly reducing installation time compared to enclosed bus ducts.
8. No maintenance is required after installation and operation, and no maintenance or upkeep is needed under normal circumstances.
