Piercing Connector – Reliable Cable Branch Connection Solution
Xi'an OUKAMU Power Technology Co., Ltd specializes in manufacturing high-performance Piercing Connector systems for low-voltage power distribution networks. Our OCMXH-70/35 model features UL94V0 flame retardant rating, withstands voltage over 4kV, and maintains insulation resistance greater than 1000 megohm. With 20 years of expertise and over 150 national invention patents, OUKAMU delivers cutting-edge cable connection technology requiring no main cable cutting or insulation stripping. The carrying capacity reaches 1.5 to 4 times that of same-size wires, ensuring superior electrical performance across industrial buildings, underground tunnels, and urban lighting projects.
What Is a Piercing Connector?
A product allows T-branch connections in electrical cable systems without interruption of the main power line. This novel gadget pierces the cable insulation to achieve good electrical contact and preserve the integrity of the main conductor.
In conventional cable branchings, the main line is cut, thus decreasing the current capacity and introducing possible places of failure. With our piercing technique, integrated design and precision engineering the disadvantages are eliminated.
The connector housing is manufactured with high strength materials with good flame retardant qualities. Controlled insulation penetration provides stable electrical contact thru the internal parts for long term stability in challenging settings.
Key Technical Features
Advanced Flame Retardant Design
OUKAMU products are rated UL94V0, the highest flame retardant standard. This degree of protection inhibits fire propagation in cable systems and improves overall electrical safety.
The housing can resist up to high temperatures without deforming. Electrical parts are insulated from temperature stress, so connection integrity is maintained when it matters.
Superior Electrical Performance
Our connections have outstanding insulation resistance of 1000 megohm. Such a high resistance prevents any leakage current and energy conservation in the whole distribution system.
Electrical strength test for verification of voltage tolerate capability exceeding 4kV. Your installation is protected from voltage surges and transient overvoltage circumstances.
The contact design gives maximum current-carrying capacity. Branch connections support 1.5 to 4 times the current of equivalent wire diameters, which reduces voltage loss and improves power quality.
Installation Without Main Cable Interruption
The groundbreaking design keeps the main cable in one piece. You can add branch circuits anywhere without cutting the primary conductor or peeling layers of insulation.
This enables to keep original cable mechanical strength and current ratin. You keep the entire capability of your distribution system and get more points of connection.
Installation flexibility allows positional change of the branch during construction. "You save time on pre-measurement and avoid costly custom cable builds.
