Key words:
Prefabricated Branch Cable (Prefabricated Branch Cable) is a backbone cable system with prefabricated branch connectors in the factory, designed for high-rise buildings, commercial complexes, data centers, and other occasions that require multi-way power distribution. Its core features are compact structure, easy installation, high reliability, can greatly reduce the site construction time and the risk of wiring errors, suitable for vertical shafts, dense power distribution network.
1. Product Structure
| Components | Material / Characteristics |
|---|---|
| Trunk cable | - Conductor: Copper (YFD-YJV) or aluminum alloy (YFD-YJHLV). - Insulation: Cross-linked polyethylene (XLPE), temperature resistance 90℃. - Sheath: Flame retardant PVC or halogen free and low smoke (LSZH). |
| Branch cable | Made of the same material as the main trunk, cross-sectional area customized according to load requirements (e.g. 16mm², 25mm²). |
| Branch connectors | -Injection molded sealed type: water and moisture resistant, IP65 protection. -Crimped type: high mechanical strength, passes tensile test. |
| Fixing bracket (optional) | Metal hooks or clamps to ensure stability when laid vertically. |
2. Product Features
✅Efficient installation
Factory prefabricated branch connector, direct lifting and laying on site, saving more than 80% wiring time.
No need to strip and crimp wires on site, avoiding poor contact caused by human error.
✅Safe and Reliable
The branch connector is waterproof, dustproof and corrosion-proof through the sealing injection molding process (in accordance with GB/T 12706).
Insulation resistance ≥1000MΩ-km, partial discharge <10pC (to ensure long-term stability).
✅Space saving
Compact design, 30% less occupied space than traditional cable + branch box solution.
Suitable for narrow shafts or dense bridges.
✅Flexible customization
The number of branches, position and cross-sectional area can be customized according to drawings (support up to 20+ branches).
Voltage level: 0.6/1kV, 8.7/15kV (high voltage pre-branching needs special design).
✅Long life
XLPE insulation is aging-resistant, with a design life of ≥30 years.
Sheath UV resistance (applicable to the exposed part of outdoor shaft).
