Winding wire SHBond® WD210 Alu

  • Enamelled round aluminium wire, thermoresistant, selfbonding
  • Insulated with THEIC mod. polyesterimide
  • plus polyamide-imide overcoat plus bonding layer
  • Class 200

SHBond® WD210 Alu is a highly thermoresistant self-bonding enamelled aluminium 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.
