Title (EN) ELECTRICAL WIRE
(FR) FIL ELECTRIQUE
Abstract:
(EN) An electrical wire comprises an elongate electrical conductor and electrical insulation that comprises: a) an inner insulating layer which comprises polyamide or polyester having aliphatic moieties; and b) an outer insulating layer which comprises an aromatic polymer. The wire exhibits good electrical and mechanical properties associated with highly aromatic polymers together with high resistance to electrical arcing.
(FR) Un fil électrique comprend un conducteur électrique allongé et une isolation électrique constituée par: a) une couche isolante intérieure composée d'un polyamide ou d'un polyester comportant des fractions aliphatiques; et b) une couche isolante extérieure composée d'un polymère aromatique. Ledit fil présente de bonnes propriétés électriques et mécaniques fondées sur des polymères fortement aromatiques ainsi qu'une grande résistance à la formation d'arcs électriques.
