Title (EN) ELECTRICAL WIRE AND CABLE
(FR) CABLE ET FIL ELECTRIQUE
Abstract:
(EN) An electrical wire comprises an electrical conductor (2), an insulating mineral layer (3) electrolytically formed on the conductor from chemically delaminated weathered mica, and a silicone polymer layer (3') and mineral layer. Preferably the layer of polymeric insulation (4) is extruded on the silicone layer. The electrical wire exhibits very good electrical properties for long periods at elevated temperatures, e.g. during a fire.
(FR) Un fil électrique comprend un conducteur électrique (2), une couche minérale isolante (3) formée par électrolyse sur le conducteur à partir de mica effrité ayant subi un clivage chimique ainsi qu'une couche polymère de silicone (3') et une couche minérale. La couche d'isolation polymère (4) est de préférence extrudée sur la couche de silicone. Ledit fil électrique présente de très bonnes propriétés électriques sur de longues périodes à des températures élevées par exemple pendant un incendie.
