Why Choose OUKAMU Branch Cable Systems?
Modern low voltage distribution networks need reliable and economic connecting methods. The traditional method of cable jointing involves cutting the main cable and determining the correct branch distances, which is labour-intensive.
This technique is revolutionised by OUKAMU product technology. Your installation teams can install branch connections where you need them, with no pre-measurement or customisation required. The primary cable conductor is not cut, so that full electrical continuity and mechanical strength are ensured throughout the length of the distribution line.
This patented design reduces material waste significantly. You will reduce labour time and installation complexity and save 2-3 meters of main cable per connecting location. The consequence is a decreased operating cost and a speedier project completion.

Three Protection Levels for Different Applications
Flame Retardant Branch Joints
Ideal for industrial and commercial buildings where fire safety regulations require flame-retardant protection. The integrated sealing design prevents fire propagation along cable routes.
Your main cable remains intact, preserving load capacity and reducing failure risks. The compact housing optimizes space utilization in cable trays and distribution rooms.
Waterproof Branch Joints (IP68)
Perfect for cable wells and direct underground burial applications. The complete resin encapsulation process creates waterproof insulation that prevents moisture ingress and electrical leakage.
Core conductors stay fully protected inside the sealed housing. You can confidently deploy these joints in humid environments, underground vaults, and outdoor installations where long-term stability matters.
Fire-Resistant Branch Joints
Essential for critical power supply circuits requiring enhanced fire protection. These joints maintain electrical connectivity during fire conditions, ensuring emergency systems remain operational.
The uncut main cable design eliminates potential weak points. You'll achieve higher fire safety ratings while maintaining the economic benefits of simplified installation.
Installation Advantages
Flexible On-Site Positioning: Adjust branch locations freely during installation. No factory pre-fabrication required. Your teams respond quickly to site condition changes without ordering custom components.
Time and Labor Savings: Simple connection procedures reduce installation time dramatically. Fewer workers complete more connection points per shift, lowering your project labor costs.
Space Optimization: Compact integrated design occupies minimal space in cable trays, tunnels, and distribution enclosures. You'll maximize building utilization rates while maintaining clean, organized cable layouts.
Maintenance-Free Operation: Once installed, the sealed joints require no periodic maintenance. The robust construction ensures reliable performance throughout the cable system's service life.
Wide Application Range
OUKAMU Branch Cable System products serve diverse infrastructure sectors:
· Commercial Buildings: Shopping centers, office towers, and mixed-use developments
· Residential Projects: Apartment complexes and residential communities

Successfully implemented in landmark projects including Zhengzhou-Wanzhou High-Speed Railway, Nantong Metro Line 2, Xi'an Olympic Village, and Shaanxi Olympic Sports Center.
How Branch Cable Joints Work
The system is used with high strength waterproof enclosure with built-in connector design. Precision terminals are rated to carry maximum current and connect main and branch cables.
A two-part polyurethane resin runs across all connecting points upon installation. The encapsulation simultaneously provides electrical insulation and mechanical protection.
The housing is translucent, or inspection ready, so that good connection can be seen confirmed before final sealing. The cable cores are fully encapsulated, providing maximum protection for both safety and durability.
FAQ
Q: Can I install branch connections without cutting the main cable?
A: Yes, absolutely. OUKAMU branch joints feature patented uncut main cable technology. You simply position the joint at your desired location, connect the branch cable through integrated terminals, and seal the assembly. The main cable's current-carrying capacity and mechanical strength remain unchanged.
Q: What cable types are compatible with your branch joint systems?
A: Our joints work with polymeric insulated cables including PVC and XLPE insulation types. They accommodate both armored (SWA) and non-armored cables with 2, 3, 4, or 5 cores. The system supports single-core and multi-core configurations for maximum installation flexibility.
Q: How do waterproof branch joints achieve IP68 protection?
A: The complete resin encapsulation process creates a continuous waterproof barrier around all electrical connections. The housing design prevents moisture ingress even during prolonged submersion. This makes them suitable for underground direct burial and permanently wet environments.
Q: What cost savings can I expect compared to traditional methods?
A: Comprehensive cost reduction reaches 300%~500% through multiple factors: 2-3 meters saved main cable per joint, reduced labor hours, elimination of custom fabrication, and lower installation complexity. Projects complete faster with fewer resources while maintaining superior reliability.
Q: Are these branch joints reusable?
A: Yes, our advanced design allows reusability for circuit modifications or upgrades. You can access the connection points when needed without destroying the entire joint assembly, providing long-term flexibility for evolving distribution requirements.
Q: Which industries benefit most from the products?
A: Any sector with complex low-voltage distribution needs gains advantages—particularly construction, municipal engineering, transportation infrastructure, and large commercial developments. Applications include tunnel lighting, metro systems, high-rise buildings, and industrial facilities requiring reliable branch connections.
