Product Introduction
JJC-2 Insulation Piercing Clamp (Overhead ABC Cable Tap-Off Connector)
Specifically engineered for branching off small-gauge lines from 10kV or lower voltage trunk networks, this premium JJC-2 Insulation Piercing Clamp perfectly accommodates main conductors of 16–95 mm² and branch lines of 1.5–10 mm². It represents a highly reliable technical solution for agricultural power grid upgrades, street lighting circuits, and fast service entry tapping.
Featuring an advanced insulation piercing, no-stripping connection design, it eliminates the need to remove the cable's outer polymeric sheath during installation, making the field splicing process incredibly time-saving, labor-efficient, and secure. It is the universally preferred universal piercing terminal for establishing reliable main-line to small-branch electrical connections.

Product Features
High-Performance Features of JJC Insulation Piercing Clamps
Premium Weatherproof Insulated Housing: The outer shell is injection-molded from specialized fiberglass-reinforced polymer profile. It provides elite dielectric strength, excellent flame retardancy, and premium aging/UV resistance under harsh outdoor sunlight.
Precision-Milled Tinned Piercing Teeth: Equipped with high-conductivity tinned brass or aluminum alloy piercing teeth. The sharp, multi-point tooth geometry ensures uniform penetration through standard cable insulation, guaranteeing low contact resistance and optimal electrical continuity.
Advanced Shear Head Torque Nut: Features an engineering-grade steel bolt paired with a smart shear-head torque nut. During installation, the outer hexagon head automatically shears off once the perfect clamping torque threshold is reached. This guarantees optimal penetration depth and stable contact pressure without over-crushing or damaging the internal conductor strands.
All-Weather Waterproof Corrosion Protection: The entire sealed housing prevents rain, ambient moisture, and dust contaminants from accessing electrical contact points. It effectively prevents galvanic corrosion and water ingress, fully complying with international electrical fittings criteria (GB/T 2314, GB/T 2315).
