Product Details

It provides reliable mechanical strength, stable electrical connection, and long-term resistance to outdoor environmental factors. This strain clamp is widely applied in low to medium voltage overhead lines, utility distribution networks, and industrial power projects, ensuring the safe and stable operation of power grids.

Product Features

  • 1. Efficient Piercing & Stable Conductivity
  • The built-in sharp piercing teeth cut through the cable insulation and make direct contact with the conductor, ensuring low contact resistance and stable electrical transmission. It is suitable for main cables (16-95mm²) and branch cables (4-50mm²), meeting most distribution line connection needs.
  • 2. Full Insulation & Weatherproof Design
  • The high-strength engineering plastic housing provides full insulation protection, preventing electric shock, short circuits and corrosion caused by rain, snow and moisture. The attached waterproof cap further enhances the sealing performance, adapting to various harsh outdoor environments.
