Fire-resistant and water-resistant halogen-free low-voltage cables

摘要

A fire-resistant and water-resistant low-voltage electrical cable including a conductor and a first internal layer to protect it against water based on a polymer compound containing no halogen, crosslinked or not, and a second layer consisting of a blend of a crystalline propylene homopolymer or copolymer and of a copolymer of ethylene and at least one alpha -olefin, optionally with a diene, and of an agent having fire retardant properties, the ratio of the thicknesses of the outer layer and the internal layer being from 1 to 7.
