Its revolutionary design provides flexible positioning, reusable components and enhanced fire-resistant, waterproof and flame-retardant protection.
Why Choose OUKAMU Branch Cable Joint Kits?
Traditional cable branching involves cutting the primary conductor which reduces the current-carrying capacity and introduces possible places of failure. Our device is a revolution in low voltage distribution because of its uncut main cable design that ensures electrical continuity and mechanical strength.
The integrated resin-sealed housing offers IP68-rated protection against moisture infiltration. That makes our products perfect for cable wells, underground burial and tough industrial locations. It gives you performance you can count on without the maintenance headaches.
Each kit can be installed in several ways. Technicians can move the branch positions on site at will – no pre-measuring or bespoke construction needed. This flexibility drastically decreases project lead times and enables straightforward adaptation in existing installations.

Key Features and Benefits
Uncut Main Cable Technology
Your main cable conductor remains intact throughout installation. This preserves the original current-carrying capacity and eliminates weak points that occur when cables are severed. Fewer connection points mean reduced risk of joint failure over time.
Superior Environmental Protection
The complete resin encapsulation process creates a waterproof barrier meeting IP68 standards. No exposed cable cores means enhanced safety in wet environments. This design prevents water ingress, electrical leakage, and corrosion that plague traditional joints.
Exceptional Fire Safety Performance
Our fire-resistant models maintain circuit integrity during fire emergencies. The specialized materials and construction elevate fire protection standards for critical applications. You gain peace of mind in high-security installations like hospitals, metro systems, and commercial buildings.
Installation Efficiency
Forget complex pre-planning and custom measurements. Technicians position branches exactly where needed during installation. The simplified process reduces skilled labor requirements and cuts installation time by 50% compared to conventional methods.
Cost-Effective Solution
Eliminating 2-3 meters of cable waste per connection adds up quickly across large projects. Reduced labor hours and faster completion times deliver immediate cost savings. The maintenance-free design eliminates ongoing service expenses throughout the product's 25+ year lifespan.
Space Optimization
Compact housing dimensions minimize footprint requirements in crowded cable trays and underground vaults. The streamlined design improves aesthetics while maintaining full accessibility for future modifications.
Applications Across Industries
Commercial and Residential Buildings
Low-voltage distribution systems in office complexes, shopping centers, and residential towers benefit from flexible branch positioning. The aesthetic enclosed design suits visible installations in modern architecture.
Industrial Facilities
Manufacturing plants and warehouses require robust connections that withstand demanding environments. Our flame-retardant and waterproof properties ensure reliable operation in challenging conditions.
Transportation Infrastructure
Metro stations, railway terminals, and highway tunnel lighting systems demand maintenance-free reliability. The proven track record in Nantong Metro Line 2 and multiple high-speed railway projects demonstrates field-tested durability.
Underground and Direct Burial
The IP68 protection rating makes these kits perfect for cable wells and direct earth burial applications. Long-term stability in moisture-exposed environments protects your infrastructure investment.
Emergency and Safety Systems
Fire-resistant models maintain power supply to critical systems during emergencies. Hospitals, data centers, and public safety facilities gain enhanced protection for essential circuits.
Installation Process
Installation is easy, requiring only simple tools and little training. Find the kit on the main cable line at the branch location you choose. Open the housing and fasten the main cable without cutting or stripping the conductor.
Strip only the insulation of the branch cable, exposing the conductors. The integrated connections are sized for your cable gauge so you connect the branch wires. 2. Mix 2-part resin compound per manufacturer's guidelines.
Pour the resin mixture into the housing, covering all connections and exposed wires. Seal the housing properly and allow adequate cure time for temperature conditions. The entire process usually takes 15-25 minutes to finish.
Quality Assurance and Innovation
Throughout our manufacturing process, we have strict quality control. Every Branch Cable Joint Kit is electrically tested, pressure tested and environmentally simulated before it is shipped. That dedication to excellence was recognised on the most challenging infrastructure projects in China.
The continuous research and development keeps OUKAMU at the cutting edge of cable connection technology. Our technical team works with industry partners to tackle developing difficulties in modern electrical distribution systems.
The patented cable T-connection technique is a real novelty in the global market. This novel method has set new norms for safety, efficiency and dependability in low voltage applications.
FAQ
Q: Which size cable is best for building wiring applications?
A: Building wiring requirements vary based on circuit loads and cable run distances. For standard domestic lighting, 1.5mm² cables typically suffice for short runs under 20 meters. However, when implementing branch connections, consider voltage drop calculations and local electrical codes. Our product accommodates main cables from 4-16mm² with branches from 1.5-10mm², covering most residential and commercial distribution needs. Always consult qualified electrical engineers for specific project requirements.
Q: How do I know if my cable connection has failed?
A: Failed cable joints exhibit several warning signs. Poor electrical continuity causes voltage fluctuations or complete power loss to downstream devices. Visual inspection may reveal discoloration, melting, or moisture inside junction boxes. Thermal imaging cameras detect hot spots indicating high resistance connections. Regular maintenance inspections catch potential issues before complete failure occurs. Our resin-sealed design eliminates common failure modes by preventing moisture ingress and maintaining stable connections.
Q: Do cable connectors deteriorate over time?
A: Traditional mechanical connectors can degrade from thermal cycling, vibration, and corrosion. Exposed connections in harsh environments deteriorate faster than protected joints. Our resin-encapsulated system isolates connectors from environmental factors, significantly extending service life. The complete sealing prevents oxidation and moisture damage that plague conventional connections. Properly installed OUKAMU joints maintain integrity for 25+ years with zero maintenance requirements.
Q: How can I reduce cable joint failure in my installations?
A: Prevention starts with quality materials and proper installation techniques. Always follow manufacturer guidelines precisely during assembly. Use compatible cable types and connector sizes specified for your application. Ensure adequate curing time for resin-based systems before energizing circuits. Implement periodic inspection programs to identify early warning signs. Choose proven products with field track records in similar environments. Our kits simplify installation while incorporating design features that eliminate common failure causes.
Q: What advantages do T-connection systems offer over traditional methods?
A: T-connection technology maintains main cable continuity, preserving current-carrying capacity and reducing failure points. Traditional methods require cutting the main conductor, creating two additional connection points and weakening overall system integrity. The uncut approach saves cable material, reduces installation time, and allows flexible positioning without advance planning. For large projects with multiple branch points, these advantages multiply significantly, delivering substantial cost and time savings.
