Wire Piercing Connector - Professional Cable Branch Connection Solution
Xi'an OUKAMU Power Technology Co., Ltd specializes in advanced Wire Piercing Connector systems engineered for low-voltage power distribution networks. With over 150 national invention patents and 20 years of manufacturing expertise, our insulation piercing connectors deliver exceptional performance with flame retardant rating UL94V0, insulation resistance exceeding 1000 megohm, and electrical strength withstanding voltage over 4kV. Successfully deployed in 10,000+ infrastructure projects including Hong Kong-Zhuhai-Macao Bridge and multiple metro systems, our connectors enable cable branch installation without cutting main conductors, maintaining 1.5-2 times carrying capacity compared to standard wire connections while eliminating downtime.
Why Choose OUKAMU Wire Piercing Connector Technology?
In the traditional sense, branching off a cable means cutting the primary conductor. This reduces the current capacity and creates weak places. Our product design breaks those boundaries.
The connector penetrates the cable insulation without stripping or disrupting the main cable. This maintains the original mechanical strength and electrical continuity of your power distribution system. It is only minutes not hours to install which saves a lot of labour expenditures.
It is intended to offer versatile on-site locating capabilities. No pre-measuring or bespoke manufacturing required. Just add the branch connection where your project needs it. This is especially useful for renovations or infrastructure upgrades.
The tiny housing requires very little space in cable trays, beneath vaults or on bridge constructions. These connections are designed for direct burial, cable wells and hard weather situations with high quality waterproof sealing IP68 protection.

Product Variants for Different Applications
Flame Retardant Wire Piercing Connector
Designed for safety-critical installations in business buildings, residential complexes and public institutions. UL94V0 flame retardant housing inhibits fire spread on cable ways.
The sealed box protects the cable cores from exposure. It complies with electrical safety rules and preserves aesthetic criteria. Ideal for visible installations in cable trays and bridge applications.
No special tools are needed for installation. Install the connector, tighten the piercing mechanism and close the housing. The entire operation takes only minutes and does not require interruption of existing power supplies.
Waterproof Wire Piercing Connector
Features integrated resin sealing technology for total moisture protection. The IP68-rated design resists continuous submersion, making it perfect for underground vaults and direct burial applications.
The connector housing is filled with a two-part polyurethane resin after installation. This forms a monolithic seal that is water impermeable and has good dielectric characteristics. The resin has good adhesion to PVC, XLPE and polymeric cable insulations.
This maintenance-free technology benefits metro systems, tunnel illumination and subterranean parking facilities. Once fitted and sealed, the connection is good for decades without any inspection requirements.
Fire-Resistant Wire Piercing Connector
Designed specifically to improve fire safety in high risk areas. This version preserves electrical continuity even in fire circumstances, providing support for emergency evacuation lighting and vital safety systems.
The fire-resistant design is a great companion to fire-rated cables, without compromising their protective features. The cable structure is still in place as there is no cutting of conductor. This maintains the fire resistant rating of the entire cable run.
This technology is essential for hospitals, metro stations, high-rise buildings and industrial sites needing uninterrupted electricity during emergencies. Provides excellent protection at a lower price than typical fire-rated junction boxes.
Installation Advantages
Traditional cable jointing requires skilled electricians, specialized tools, and significant time investment. Our Wire Piercing Connector simplifies this process dramatically.
Position the connector body around the main cable at your desired branch location. The piercing teeth penetrate the insulation when you tighten the fasteners. Internal contact blades establish electrical connection with the conductor without cutting it.
Connect your branch cable to the designated terminal. Apply the protective cover or resin seal depending on your product variant. The installation completes without power interruption to existing circuits.
This approach reduces installation time by 60-70% compared to conventional methods. Lower labor costs and faster project completion improve your bottom line while maintaining superior connection quality.
Applications Across Industries
Infrastructure Projects: Metro systems, railway electrification, highway tunnel lighting, and bridge power distribution benefit from field-adjustable installation and weatherproof protection.
Commercial Buildings: Shopping malls, office towers, and hotels utilize these connectors for flexible power distribution to tenant spaces without disrupting main feeders.
Industrial Facilities: Factories and warehouses require reliable branch connections for machinery and lighting. The maintenance-free design reduces operational costs over the facility lifetime.
Residential Developments: Apartment buildings and housing complexes achieve code-compliant branch connections with improved safety margins and reduced installation expenses.
Municipal Projects: Street lighting, traffic signals, and public facility power distribution systems gain flexibility and reliability through no-cut branching technology.
Quality Assurance and Project Success
OUKAMU connections are proved reliable in China's most demanding infrastructure projects. Our connection technology is used in Hong Kong-Zhuhai-Macao Bridge, several high-speed railway lines and metro systems in major cities.
Over 10,000 successful project installs in the real world. Proven. Our products survive high temperature swings, humidity, vibration and chemical exposure, while retaining electrical integrity.
Each connector passes strict manufacturing tests, including high-voltage withstand tests, insulation resistance measures, and mechanical stress evaluation. This QC assures that every unit behaves the same.
We have third party testing and certification to verify our specs. Independent testing facilities verify our flame retardant ratings, IP protection levels and electrical characteristics are in accordance with international standards.
FAQ
Q: Can I install these connectors without cutting the main power cable?
A: Yes, that's the primary advantage. The piercing mechanism penetrates insulation to establish electrical contact while leaving the main conductor completely intact. This preserves full current-carrying capacity.
Q: What cable types are compatible with OUKAMU products?
A: Our connectors work with PVC, XLPE, and polymeric insulated cables. They accommodate single-core and multi-core configurations from 10mm to 300mm conductor sizes in 2, 3, 4, and 5 core arrangements.
Q: How do waterproof versions achieve IP68 protection?
A: After mechanical installation, you fill the housing with two-part polyurethane resin. This creates a complete moisture barrier bonding to both the connector and cable insulation for permanent waterproof sealing.
Q: Are special tools required for installation?
A: Standard electrical tools suffice for most installations. Basic wrenches tighten the piercing mechanism. Resin-sealed versions require mixing equipment for the two-part compound, but no specialized apparatus.
Q: Can these connectors be installed on energized cables?
A: We strongly recommend de-energizing cables before installation for safety. While the design includes insulation protection, following proper lockout-tagout procedures protects installation personnel.
Q: What maintenance do installed connectors require?
A: Properly installed connectors are maintenance-free. Resin-sealed waterproof versions require no periodic inspection. Flame-retardant versions in accessible locations may be visually inspected during routine facility maintenance.
