Low Voltage Insulated Piercing Connector - Professional Cable Branch Connection Solution
Xi'an OUKAMU Power Technology's Low Voltage Insulated Piercing Connector represents a breakthrough in cable T-connection technology with over 150 national invention patents. The OCMXH-240/95 model delivers flame retardant performance at UL94V0 class, insulation resistance exceeding 1000 megohm, and electrical strength withstanding voltage above 4kV. This innovative connector requires no main cable cutting or insulation stripping, maintaining 1.5-2 times the carrying capacity of standard same-size wires while supporting flexible branch positioning at any location.
What Is a Low Voltage Insulated Piercing Connector?
Product is a smart cable branch solution for power distribution systems. Unlike typical connectors where cable cutting and intricate splicing are required, piercing connectors create reliable metal-to-metal contacts thru the insulation layer.
The technology allows fast tap connections to uncut mains. The connector is drilled via the cable insulation to the conductor making a solid electrical connection without affecting the integrity of the main line.
OUKAMU's design requires no cable stripping or specific customisation. Your installation crew can place branches as they build on site, lowering labour costs and installation time dramatically.
Key Features and Benefits
Uncut Main Cable Construction
The connector maintains the integrity of your main cable. You have full current carrying capacity and mechanical strength along the whole length of the cable run. This design lowers failure risks and increases the service life of the cable.
Your power distribution system remains energised during branch installation. This ensures that there is no downtime, resulting in higher project efficiency and decreased expenses of down time.
Superior Insulation and Protection
The integrated resin encapsulation ensures complete sealing and IP68-rated protection. The sealed design avoids water penetration, leakage and environmental pollution.
Your connections are secure in cable wells, underground burial, bridge installations and other hostile settings. The clear polycarbonate casing lets you look inside the connector without opening it up.
Flexibility Of Installation
Flexibility in installation is a big plus. Branches can be positioned anywhere you want without having to measure or order a specific bespoke setup.
The installation is done with simple hand tools. Your team decreases time, labour needs and overall project expenses. The tiny form requires very little room in cable trays, conduits and junction boxes.
Safety Performance for Fire
True fire resistant performance improves electrical safety standards. UL94V0 flame retardant grade guarantees reliable functioning at elevated temperatures.
Your crucial power supply circuits are also protected. This feature is especially useful in tunnels, subways, public facilities and high-rise structures where fire safety is of utmost importance.

Installation Guide
Preparation Steps
Clean the surface of the main cable where you will join the branch. Follow your safety procedures to keep the cable energised or de-energised.
Select the proper connector size for your main cable and branch cable requirements. Verify that the kit has all of the parts.
Process of Connecting
At the branch point you want, position the connection housing over the main cable. Insert branch cable into port.
Tighten the pierce screws to the prescribed torques. The contact teeth pierce the two cable insulations to connect to the conductors.
Sealing and Protection
Pour the two part resin compound into the housing cavity. All the connections are embedded in resin for electrical isolation and mechanical protection.
Be sure to let it cure enough before energising the circuit. The sealed unit now offers IP68 protection against environmental influences.

FAQ
Q: Can I install the connector on energized cables?
A: We recommend following local electrical safety regulations. While the design allows hot-line installation by qualified personnel using appropriate safety equipment, de-energized installation is always safer for your team.
Q: What cable types are compatible?
A: The connector works with PVC, XLPE, polyethylene, and armored cables. Both single-core and multi-core configurations from 2 to 5 cores are supported across copper and aluminum conductors.
Q: How long does installation take?
A: Experienced installers complete a single branch connection in 15-20 minutes. This includes positioning, piercing, and resin encapsulation with curing time.
Q: Do I need special tools?
A: Basic hand tools suffice for installation. A torque wrench ensures proper contact pressure. No specialized crimping equipment or heat sources are required.
Q: What is the expected service life?
A: When properly installed, the connector matches or exceeds your cable's service life. The sealed design prevents degradation from environmental exposure.
Q: Can connectors be reused or relocated?
A: These connectors create permanent connections. Once installed and sealed, relocation is not recommended. Plan branch positions carefully during installation.
