Title (EN) WIRE
(FR) FIL
Abstract:
(EN) An electrical wire comprises an elongate electrical conductor and electrical insulation that comprises: (a) an inner insulating layer which comprises a polyamide that has a glass transition temperature of at least 0°C; and (b) an outer insulating layer with comprises a fluorinated polymer, for example an ethylenetetrafluoroethylene copolymer. The wire exhibits a balance of properties, especially weight and cut through resistance combined with high resistance to wet and dry tracking, that make the wire useful $i(inter) $i(alia) for airframe wire.
(FR) Un fil électrique comprend un conducteur électrique allongé et un isolant électrique qui comporte: (a) une couche isolante interne contenant un polyamide ayant une température de transition vitreuse d'au moins 0°C; et (b) une couche isolante externe contenant un polymère fluoré, tel qu'un copolymère d'éthylène-tétrafluoroéthylène. Ledit fil présente des propriétés équilibrées, telles que notamment une résistance au poids et au sectionnement combinée avec une résistance élevée au cheminement à l'état humide et sec, ce qui permet l'emploi dudit fil notamment dans les cellules d'aéronefs.
