PHYSICAL PROPERTIES

  • The limiting values of solid copper conductor diameter, Elongation at Break and other technical details are as given in IS 8783 (Part 1) : 1995.
  • The properties of PVC compound are as given in IS 8783 (Part 2) : 1995.
  • The Winding Wires are tested as per IS 8783 (Part 3) : 1995.

INSTRUCTION FOR USE

  • Do not stack more than 4 coils otherwise, bottom coil is likely to get damaged due to upper coil weight.
  • Always keep away winding wire from those things having sharp edges and equipment generate heat to avoid unintentional damage. Also avoid welding spark falling on winding.
  • Motor manufacturers must ensure proper cable joining after winding to avoid megger or winding failer.
