Abstract (en)
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.
Abstract (fr)
Le fil émaillé comporte un conducteur et au moins deux couches d'émaillage dont au moins l'une d'elles est chargée de particules faiblement conductrices. Il est caractérisé en ce que la couche d'émaillage la plus extérieure (4) est non chargée desdites particules et constituée en une résine thermo-adhérente et la couche (3) directement sous-jacente à celle-ci est en résine chargée desdites particules. Application : fil émaillé de bobinage. <IMAGE>
