Piercing Connector

JJC insulator piercing connectors are applicable for all types of LV-ABC conductors as well as connections in service line systems, building electrical systems and street lighting systems.

Installation can be easily done by tightening bolts to force teeth to penetrate the insulation of the main line and tap line simultaneously. Stripping of insulation is avoided for both lines. Insulation material is made of weather-resistant glass fiber-reinforced polymer.

Insulation Piercing Connectors are mainly composed of an insulating shell, piercing blade, waterproof rubber pad and torque bolt. And the piercing connector has the following characteristics:

  1. Puncture structure, simple installation, no need to strip the insulated wire;
  2. Torque nuts, constant piercing pressure, ensure good electrical connection without damaging the wires,
  3. Self-sealing structure, moisture-proof, waterproof, anti-corrosion, prolong the service life of insulated wires and clamps
  4. Adopt a special contact blade, suitable for copper (aluminum) butt joints and copper-aluminum transition
  5. The electrical contact resistance is small, the contact resistance is less than 1.1 times the resistance of the equal-length branch wire, which meets the DL/T765.1-2001 standard
  6. Special insulating shell, anti-light and environmental aging, dielectric strength>12KV
  7. Arc surface design, suitable for the same (different) diameter wire connection, wide connection range (0.75mm2-400mm2)
