* Mechanical Dimension Tolerance as per IS 2102 (Part-1):1993, Designation C.

  • All Copper products are Electro-tinned to B.S. standard and this prevents it from corrosion and oxidation.
  • P.V.C. insulation is provided to terminals for exceptional Die-Electric strength and for supporting the wire insulation at the base of the terminal, thereby ensuring that no bare wire is exposed.
  • P.V.C. insulation with copper sleeve fitted over the terminals barrel provides circumferential insulation support to the wire prevents the loss of connection due to vibration, of flexing in use.
