FIL EMAILLE DE RESISTANCE ELEVEE AUX DECHARGES PARTIELLES

摘要

The enamelled wire (1) comprises a conductor and at least two layers (2,3,4) of enamelling, one of which is charged with particles having a weak electrically conductivity. The wire is surrounded by the enamelled layers, the outermost of which (4) is not charged with the particles but consists of a thermo-adhesive resin. The layer (3) immediately beneath the outside layer is the layer which contains the particles having a low electrical conductivity. The innermost layer (2) may also be charged with these conductive particles.
