Insulation Piercing Connector TTD121F 


The insulation piercing connectors are applicable for all types of LV-ABC conductors as well as connections in service line system, building electrical system and street lighting system. Insulation piercing connectors can be easily done by tightening the bolts to force the teeth penetrate the insulation of main line and tap line simultaneously. Stripping of insulation is avoided for both lines.
● Main line: Insulated aluminium cable
● Tap line: Insulated aluminium cable or Insulated copper cable
● Body is moulded from tough and weather resistant materials
● Special designed shear head bolt allows efficient installation under controlled shear torque which ensure the contact teeth properly penetrate the conductor without damaging the mechanical strength of the conductor
● Tested for watertightness at the voltage of 6kV for 1min under water
● Safe live-line installation
● Seals and grease are applied to prevent moisture entering the cable and connector which guarantees excellent waterproof and corrosion resistant performance
● End cap is attached to the body. No loose parts could fall to ground during installation 
● Standard: EN 50483-4, NFC 33-020, NFC 33-004
