TTD Insulation Piercing Connector

Our TTD Series Insulation Piercing Connector is essential overhead line hardware specially designed for quick branch connection of ACSR cables and insulated power wires without stripping cable insulation. Made of high-strength anti-aging engineering plastic shell and conductive tin-plated alloy piercing blades, it features excellent waterproof, anti-corrosion and weather-resistant performance, stable electrical conductivity and long outdoor service life.(ILAC-MRA Test Report Available)
No wire stripping tools are required during installation; the built-in sharp metal teeth can pierce the cable sheath accurately to form a reliable conductive loop, greatly improving construction efficiency and avoiding wire damage. Equipped with sealed rubber gaskets, it effectively blocks rainwater and moisture intrusion to prevent short circuits, fully adapting to overhead distribution network projects.
Compatible with various specifications of ACSR cables and low-voltage overhead conductors, this piercing connector boasts compact structure, simple operation and firm clamping force. It is a standard matching fitting for overhead line hardware, widely applied in urban power distribution, rural overhead power transmission and outdoor cable branching projects worldwide.
