Nylon vibration proof insulated ring terminals

type : ВНКИ

By TU  3424-001-59861269-2004

• Designed for termination by crimping stranded flexible copper wires and subsequent mounting to the terminals of electric equipment on the basis of screw fixation

• Insulation material: self-extinguishing nylon. Halogen-free

• Temperature resistance of insulation: 105 °C

• Terminal material: copper ,grade M1

• Terminal plating: electrolytic tinning

• Max voltage: 690 V

• Design features:

  • additional copper sleeve increases the mechanical strength of the connection with the wire by 25-30% and makes the connection vibration-resistant
  •  "Easy Entry" implementation: copper sleeve forms a cone-shaped entrance for the fast establishment of the copper wires into terminals
  • transverse notches provided on the inner surface of the tubular part of terminals to increase the mechanical strength of the connection with core

 •Translucent cuff allows controlling the depth of entry of the cores

 •Advanced multi - dimensional ranges of crimping

• Crimping of conductor on top of the insulating cuffs
