Winding wire SHBond® WD210

  • selfbonding enamelled round cu.wire, bondable
  • insulated with theic-mod. polyesterimide
  • plus Amide-Imide overcoat
  • plus bonding layer aromatic polyamide
  • class 200

"SHBond® WD210" is a highly thermo-resistant self-bonding enamelled copper wire of heat performance class N. With this wire the excellent resistance and insulation properties of SHTherm® 210 - Dualcoat are combined with the special application possibilities of an additional bonding layer which is based on mod. aromat. Polyamide and which enables the production of heat bonded wire windings. Using this type of thermo-setting wire the heat bonding process is economic, as it can be executed within seconds and can support automatic processing. It is not harmful to the environment. Heat bonded windings show excellent thermal and mechanical stability and high resistance to climatic demands and many chemical agents. Sophisticated process technology and process setting ensure easy mouldability, good elongation and excellent insulation properties.
