The TTD151FJ Insulation Piercing Connector is designed for safe, fast, and reliable branching of low-voltage ABC cables, copper cables, and aluminum conductors without stripping insulation. With a fully sealed structure and stainless-steel piercing teeth, the TTD151FJ insulation piercing connector ensures secure electrical contact while maintaining waterproof performance and corrosion resistance, making it ideal for outdoor power distribution networks. This connector supports stable current flow, minimizes installation errors, and reduces field maintenance in harsh environments including rain, humidity, UV exposure, temperature fluctuations, and coastal corrosion.
• Waterproof, sealed design (IP67)
• No insulation stripping required
• Stainless steel piercing teeth ensure conductivity
• Flame-retardant and UV-resistant body
• Compatible with copper and aluminum cables
• Quick installation using torque control bolt
