YUANKY Insulation Piercing Connector Clamp is a high-performance cable connection component designed for fast, reliable branch tapping on low-voltage insulated power lines. Constructed with a high-strength aluminium alloy internal body and an anti-UV polyvinyl chloride (PVC) insulation cover, this piercing connector delivers excellent mechanical strength, stable electrical conductivity and durable weather resistance for both indoor and outdoor electrical installations. It eliminates the conventional need for cable insulation stripping, significantly simplifying branch connection work and improving on-site construction efficiency.

Engineered with specially designed contact teeth, the connector is optimized for aluminium conductor connections. The installation process is straightforward: place both the main conductor and branch conductor parallel into the tooth grooves of the clamp, then tighten the bolts. The sharp contact teeth pierce through the insulation layers of both conductors simultaneously, creating a secure, low-resistance metal-to-metal electrical connection. The matching insulation cover provides complete waterproof sealing and reliable environmental protection. Mechanically, the connector maintains full structural integrity without distortion or breakage even under the conductor’s breaking force. Electrically, its temperature rise under rated current and short-circuit conditions remains lower than that of the connecting conductors, ensuring stable, safe long-term operation.

This insulation piercing connector serves a wide range of low-voltage power distribution scenarios. In building distribution systems, it is widely used for cable branch connections in residential buildings, commercial complexes and industrial workshops, enabling convenient tap-off from main feeders to individual floor or equipment circuits. For overhead low-voltage insulated line networks, it creates reliable T-connections for main line branching, making it ideal for rural power grid construction and urban distribution network upgrades. It is also extensively applied in outdoor lighting systems, street lamp circuits, campus power distribution and municipal engineering projects, where its UV-resistant and waterproof properties ensure consistent performance in exposed outdoor environments. Additionally, it is a preferred solution for renovation and retrofitting projects, as it allows branch connections without cutting the main line, reducing construction downtime and service interruption.

With its labor-saving piercing design, reliable mechanical performance and excellent environmental adaptability, YUANKY piercing connector clamp provides a cost-effective, efficient connection solution for electrical contractors, power utilities and building engineering projects worldwide.
