What Makes OUKAMU Piercing Wire Connectors Different?
Our insulation piercing patented concept revolutionises the method of branch connections in cables. Unlike standard jointing methods which need a break in the cable, our technology ensures the conductor remains continuous throughout the installation process.
The connector employs precision manufactured contact points that penetrate via the insulating layers without injuring the conductor cores. This maintains the original cable ampacity and mechanical robustness while providing dependable electrical channels for branch circuits.
Our device stands out with its installation versatility. You can make T-connections anywhere along your primary cable length without pre-measurement or custom fabrication. Such flexibility dramatically decreases material waste and labour expenses.
Our sealing design is incorporated to prevent infiltration of moisture to IP68. Polycarbonate housing withstands tough subterranean conditions, cable wells and direct burial applications with constant performance for decades.

Key Features and Benefits
Uncut Main Cable Design
Your main conductor is intact during installation. This retains full current-carrying capacity, and removes the weak areas formed by typical splicing procedures. Cable mechanical strength is still 100% of original specification.
Flexible On-Site Installation
Position your branch connections where you want them in your design. No previous measurement or factory customisation was needed. Installation crews might change branch placements in the field throughout the construction.
Efficient Configuration Space
Compact housing occupies a minimum of area in cable trays, trenches or junction boxes. Its thin design enables for improved cable management and maximum available routing space in crowded installations.
Advanced Seal Technology
Two-part polyurethane resin encapsulation gives total environmental protection. The connector provides long-term insulation of conductors against moisture, dust and corrosive substances.
Improved Fire Safety
Fire resistant types keep the circuit operating under hot conditions. In the presence of fire, high-temperature materials keep conductor paths intact, supporting emergency power systems and life safety circuits.
Cost-Effective Implementation
Faster installation means less labour cost. Simpler procedures and fewer tools mean less staff requirements and faster project completion.
Application Scenarios
Industrial Facilities
Manufacturing plants, warehouses, and processing centers benefit from quick branch circuit additions. Our Piercing Wire Connector systems support machinery relocations and production line reconfigurations without shutting down main feeders.
Commercial Buildings
Office complexes, retail centers, and hospitality properties require flexible power distribution. Install branch circuits for tenant improvements or lighting upgrades while maintaining continuous power to existing loads.
Residential Developments
Multi-unit housing projects achieve efficient riser distribution. Common area lighting, elevator circuits, and unit service drops connect cleanly without interrupting vertical feeders.
Transportation Infrastructure
Tunnel lighting systems, metro stations, and highway installations demand reliable connections in challenging environments. Waterproof enclosures and corrosion-resistant materials ensure decades of maintenance-free operation.
Underground Applications
Direct burial scenarios and utility vault installations benefit from complete moisture protection. Cable joint resin formulations provide excellent adhesion to all insulation types while maintaining dielectric properties.
Installation Advantages
Simple procedures reduce training requirements for installation crews. The system uses standard electrical tools without specialized equipment. Step-by-step guides ensure consistent results across multiple installation teams.
Real-time positioning allows design modifications during construction. You can respond to unforeseen obstacles or owner requests without ordering custom components or delaying schedules.
Quality control improves through visual inspection capabilities. Transparent housing options let you verify proper conductor placement and resin fill before final sealing.
Performance and Reliability
Our connectors undergo rigorous testing protocols exceeding international standards. Thermal cycling, vibration resistance, and accelerated aging tests validate long-term performance characteristics.
Proven track record in demanding applications demonstrates field reliability. Installations remain operational in extreme temperatures, high humidity, and corrosive atmospheres across diverse geographic regions.
The integrated design eliminates multiple potential failure points. Fewer components mean reduced maintenance requirements and extended service intervals compared to traditional junction methods.
