SynWire – Winding Wires SynWire type 155, Copper Wire, round, enamelled, self bonding

  • enamelled round copper wire, self-bonding
  • insulated with solderable polyurethane
  • aliphatic polyamide
  • class 155

The SynWire type 155 is a thermal class F enamelled copper wire which can be directly soldered and self bonded under heat. With a solder bath temperature from 390 °C the wire is solderable without prior removal of the insulation film.

The SynWire type 155 is a 2-ply self bonding wire with a high resoftening temperature which is used to produce thermally stimulated windings in an integral and thus space saving, machine suitable, efficient and cost-effective manner. In contrast to impregnants, these windings can be bonded quickly and environmentally friendly. The self bonding windings are characterised by their thermal and mechanical stability. State-of-the-art processing techniques, process controls and checks ensure the constant high quality of these wires.
