Advanced Cable Branch Joint Technology
OUKAMU product solutions turn standard electrical connections on their head. Patented uncut main cable technology. The branch joints are flexible to install on site, without cutting the cable or pre-measuring, and without disturbing the main conductor in the way conventional methods do.
Housing with integral snap-shut construction Impact resistant materials with IP68 certified waterproof sealing. It offers better protection in harsh settings such as cable wells, underground burial and outdoor installations.
Our two-part polyurethane resin encapsulation has outstanding adhesion properties to PVC, XLPE and polymeric cable insulation. The full sealing process eliminates water entry, electrical leakage and environmental pollution, and maintains long-term operational stability.
Key Product Features and Benefits
Easy Installation No Cutting Cables
Installation complete. Main wire conductor unharmed. This reduces possible failure spots while preserving original current carrying capacity and mechanical strength. The on-site branch location can be adjusted and does not require pre-customization.
Better Fire and Water Protection
Our flame retardant formulation fulfils tough fire safety regulations. Integrated resin potting offers Class IP68 waterproof performance, suited for submersible applications. And there are fire-resistant versions that give added protection for key infrastructure projects.
Cost Efficient & Time Efficient
Each installation saves 2 to 3 meters of main cabling material. The simplified approach takes 50% less time to install than traditional cut and splice methods. Less labour = Big savings on the cost of the project
Maintenance-Free
Full encapsulation means that there are no exposed conductors or connecting points. The sealed design eliminates oxidation, corrosion and environmental deterioration. This allows a reliable functioning across the cable operational life without periodical maintenance interventions.

Wide Application Scenarios
The OUKAMU branch cable joints are applied in various infrastructure sectors where reliable low voltage distribution connections are needed. Our solutions work like a charm in industrial plants, commercial buildings, residential complexes, metro systems and public infrastructure projects.
Our waterproof encapsulation method is a benefit for underground cable networks. The IP68 protection grade allows for safe operation in flooded cable wells and direct burial applications. Our fire resistant variations are used in transportation infrastructure such as highways, railroads and tunnels for better safety performance.
Flexible branch locations Simplified wiring layouts Building Electrical Systems This decreases the area requirement for installation and enhances the utilisation efficiency of architecture. Our Cable Jointing Cable Joint Connector solutions are designed for new build and refurbishment of ageing electrical systems.
Installation Process and Quality Assurance
The simplified installation procedure requires minimal specialized tools. After stripping cable insulation to specified lengths, connectors attach to conductors using mechanical compression or crimping methods. The branch joint housing assembles around connections before two-part resin injection completes the encapsulation.
Curing time ranges from 30 minutes to 2 hours depending on ambient temperature. The transparent polycarbonate housing design allows visual inspection during resin curing. This ensures complete filling and proper sealing before energization.
Quality control procedures include electrical continuity testing, insulation resistance measurement, and waterproof integrity verification. Each production batch undergoes factory testing to validate compliance with national and international standards.

FAQ
Q: What advantages do branch joints offer over traditional cable splicing?
A: Branch joints eliminate main cable cutting, preserving full current capacity and mechanical integrity. Installation flexibility allows branch positioning adjustments on-site without pre-measurement. This saves material costs, reduces installation time, and minimizes potential failure points compared to cut-and-splice methods.
Q: Are OUKAMU cable joints suitable for outdoor and underground installations?
A: Yes. Our waterproof models feature IP68-rated sealing suitable for submersible conditions, direct burial, and flooded cable wells. The complete resin encapsulation prevents moisture ingress and environmental contamination. Fire-resistant variants provide additional protection for critical applications requiring enhanced safety performance.
Q: What cable types are compatible with your product systems?
A: Our branch joints accommodate PVC, XLPE, and polymeric insulated cables with copper conductors. Compatible configurations include 2, 3, 4, and 5 core cables from 2.5mm² to 70mm² cross-sectional area. Both stranded and solid conductor types work with appropriate connector selections.
Q: How does the uncut main cable installation method work?
A: The branch joint clamps onto the main cable without severing conductors. Piercing connectors penetrate insulation to establish electrical contact while maintaining conductor continuity. This preserves the main cable's structural integrity and current-carrying capacity throughout its length.
Q: What quality certifications do OUKAMU products meet?
A: Our cable joint systems comply with GB/T 14048.7-2016 and relevant international safety standards. Manufacturing processes follow ISO quality management systems. Product performance testing includes electrical, mechanical, and environmental validation to ensure reliable operation across diverse application conditions.
