What Are Insulation Piercing Branch Connectors?
The items are sophisticated electrical connection devices for low-voltage distribution systems. They allow branch connections to be made directly to the main power cables without disrupting service or compromising the cable's integrity.
Unlike traditional jointing procedures, these connections have precision manufactured piercing teeth that penetrate the insulation layer. It gives a safe electrical contact with the conductor, while retaining the original load capacity and mechanical strength of the cable.
The technique is especially beneficial for lighting infrastructure projects, commercial buildings, underground facilities and tunnel lighting systems. This simplifies installation, decreases labour costs and increases the overall reliability of the system.

Outstanding Product Features
Main Cable Cutting Not Required
When installing branches, the primary cable is totally intact. This allows the current carrying capacity and mechanical strength of the conductor to be maintained hence greatly decreasing sites of possible failure.
The uncut design also allows you to add branch connections without interrupting power to existing loads. This is especially the case with renovation projects and system extensions.
Flexible On-Site Installation
No pre-measurement or special manufacturing is needed. Branch placements are flexibly adjustable on installation for optimum flexibility on construction sites.
That flexibility cuts down on planning time and lets design modifications be made quickly. Your installation teams will love the simpler workflow and less material waste.
Full Waterproof Protection
Our integrated resin encapsulation gives IP68 protection. The entire point of connection is protected against moisture, making these connections ideal for cable wells, underground burial and other harsh environments.
The potting compound provides electrical insulation and mechanical protection. The two-in-one architecture is key to the long-term reliability even under difficult environments.
Improved Fire Safety Performance
Special fire resistant variants provide real high level fire protection for sensitive facilities. The sealed housing prevents exposed conductors, complying with severe safety requirements for public facilities and commercial structures.
This means they are suitable for hospitals, metro stations, sports centers and other projects where fire safety is of utmost importance.
Space Saving Compact Design
Integrated housing design requires less installation space than standard connection boxes. This is particularly helpful in congested cable trays and confined underground vaults.
You get cleaner, more organised installations that make future maintenance and inspections easier.
Diverse Application Scenarios
Our Insulation Piercing Branch Connectors serve multiple industries and installation environments:
Infrastructure Projects: Successfully deployed in major transportation projects including high-speed railways, metro systems, and landmark bridges across China.
Commercial Buildings: Ideal for shopping centers, office complexes, and residential towers requiring flexible power distribution without main cable interruption.
Industrial Facilities: Factory floor installations benefit from the ability to add branch circuits without production shutdowns.
Underground Systems: Waterproof models excel in subway stations, underground passages, and direct-burial applications where moisture protection is essential.
Tunnel Lighting: Cost-effective solution for tunnel construction and lighting systems with simplified installation and maintenance-free operation.
Municipal Lighting: Street lighting and landscape illumination projects gain efficiency through quick branch connections at any desired location.
Installation Advantages You'll Appreciate
The installation of these connectors will save much time and effort. There's no need for particular talents or pricey gear on your team to make professional-quality connections.
The approach removes many traditional steps: no cable cutting, no insulation stripping, no complicated splicing operations. This means projects are completed faster and installation costs are reduced.
You get the main cable working. Now you can operate on live distribution systems if it is safe to do so. This flexibility is a great advantage in terms of renovations and system updates.
Maintenance free design will offer reliable service throughout the life of the cable once installed. There are no recurrent expenses for inspections or replacements.
Quality Backed by Innovation
With over 150 national invention patents, OUKAMU represents the forefront of cable connection technology. Our proprietary designs include 20-year patent protection periods, reflecting genuine technological innovation.
Our manufacturing facility integrates research, development, and production capabilities. This vertical integration ensures consistent quality control and rapid response to custom requirements.
The products undergo rigorous testing for electrical performance, environmental resistance, and mechanical durability. Each connector meets or exceeds international standards for low-voltage electrical installations.
FAQ
Q: Can these connectors work with both copper and aluminum cables?
A: Yes, our connectors accommodate copper-to-copper, aluminum-to-aluminum, and copper-to-aluminum connections. The piercing teeth material is selected based on your specific cable type requirements.
Q: Do I need to shut down power to install branch connections?
A: While safety protocols depend on your local regulations, the uncut main cable design allows installation without interrupting main conductor continuity. Always follow proper electrical safety procedures for your application.
Q: What cable sizes are compatible with these connectors?
A: Our product range covers conductors from 10mm through 300mm for 2, 3, 4, and 5 core cables. Both single-core and multi-core polymeric cables are supported.
Q: How does the waterproof rating perform in actual underground installations?
A: The IP68-rated models provide complete submersion protection. The integrated resin encapsulation creates a permanent seal suitable for cable wells, direct burial, and other wet environments. Successful deployment in thousands of underground projects confirms long-term reliability.
Q: Are special tools required for installation?
A: Installation requires only basic hand tools. The connector design eliminates needs for cable strippers, specialized crimping tools, or heat-shrink equipment. This simplicity reduces both equipment costs and training requirements.
Q: What is the expected service life of these connectors?
A: When properly installed, these connectors provide maintenance-free service matching or exceeding the operational lifetime of the connected cables. The sealed design protects against environmental degradation and electrical stress.
