Pre-fabricated Branch Cable System (Rated Voltage 1kV)
Factory-prefabricated branch connectors enable direct on-site installation without field splicing — designed for trunk-type low-voltage power distribution systems in high-rise buildings and similar facilities.

Overview
Pre-fabricated branch cables (rated voltage 1kV) are complete cable assemblies consisting of copper or aluminium core main trunk cables with factory-installed proprietary branch connectors, designed for trunk-type low-voltage power distribution systems.
Branch connectors are assembled and sealed under factory conditions, allowing direct on-site installation without complex field splicing operations. This significantly improves installation efficiency while ensuring reliable and consistent connector quality.
Key Capabilities
- Factory-prefabricated branch connectors with stable and consistent connection quality
- Eliminates field splicing for simplified installation and reduced construction time
- Proprietary sealed connector structure with reliable waterproof and dustproof performance
- Suitable for trunk-type low-voltage power distribution systems
- High-rise and super high-rise buildings
- Industrial and commercial buildings
- Residential complexes and public facilities
- Applications with specific requirements for installation efficiency and connection reliability
Standards
- GB/T 12706
Compliant with applicable national and industry standards
Operating Conditions
| Rated voltage | 0.6/1kV |

| Minimum ambient temperature during installation | 0°C |
| Minimum bending radius (main cable) | 12D (D = cable outer diameter) |
Construction & Technical Performance
Construction
- Conductor: stranded copper or aluminium core
- Insulation: cross-linked polyethylene (XLPE) or polyvinyl chloride (PVC)
- Branch connector: factory-prefabricated sealed connector joining the main cable and branch cables
- Sheath: polyvinyl chloride (PVC) or other suitable sheathing material
Quality & Consistency
Branch connectors are manufactured and sealed in a controlled factory environment, ensuring connection reliability and structural consistency for each assembly, meeting electrical safety and installation reliability requirements for engineering applications.
Installation Considerations
- Branch connectors are factory-prefabricated and must not be disassembled or altered on site
- Installation must strictly follow design drawings to ensure the main cable, branch cables, and connector positions meet design requirements
- The positions, quantity, and specifications of branch connectors must be confirmed at the ordering stage and cannot be changed after manufacturing
