Insulation Piercing Connector

Our insulation piercing connectors are high-performance power fittings for splicing and branch tapping of insulated conductors. They pierce directly through cable insulation without stripping, enabling fast, safe electrical connections — a superior alternative to traditional crimp and wrap methods.

Key Features

Quick Installation, No Stripping: No insulation removal or cable cutting needed. Make branch taps at any line position; one technician can complete installation with a standard socket wrench, cutting labor time sharply.

Reliable Electrical Contact: Torque shear nuts break off at preset torque for uniform piercing pressure. Tin-plated copper blades deliver low contact resistance, corrosion resistance and stable long-term performance.

Weatherproof & Durable: Reinforced flame-retardant housing with a fully sealed waterproof structure. Dielectric strength ≥12kV, suitable for outdoor, underground and humid environments.

Wide Compatibility: Works with copper and aluminum conductors (0.75–400mm²), supporting 0.6/1kV and 10kV systems for same/different size connections.
