Title (EN) ELECTRICAL WIRE
(FR) FIL ELECTRIQUE
Abstract:
(EN) An electrical wire comprises an elongate electrical conductor, an inorganic arc-control layer surrounding the conductor, an insulating layer which surrounds the arc-control layer and comprises an aromatic polymer, and a secondary tracking control layer surrounding the insulating layer, the secondary tracking control layer having a comparative tracking index of at least 300V. The wire exhibits good electrical and mechanical properties characteristic of highly aromatic polymers together with good resistance to dry arcing and wet tracking.
(FR) Un fil électrique comprend un conducteur électrique allongé, une couche de régulation d'arc inorganique qui entoure le conducteur, une couche isolante qui entoure la couche de régulation d'arc et qui comporte un polymère aromatique, ainsi qu'une couche secondaire de régulation du cheminement qui entoure la couche isolante et qui présente un indice comparatif de cheminement d'au moins 300 V. Ledit fil présente de bonnes propriétés électriques et mécaniques, caractéristiques des polymères fortement aromatiques, ainsi qu'une bonne résistance à la formation d'arcs à sec et au cheminement à l'état humide.
