Mica insulation metal sleeve protection high flame retardation fireproof cable

A mica insulation metal sleeve protection high flame retardation fireproof cable belongs to the power cable technical field, and comprises a cable core and a sheath; the features are that the cable core is formed by twisting a plurality of wire cores; the cable core is extruded by a heat isolation protection function layer; the heat isolation protection function layer is extruded by a high-toughness oxygen isolated high flame retardant cover; the sheath is made of low smoke halogen free high-molecular material and extrudes outside the high-toughness oxygen isolated high flame retardant cover; the wire core comprises twisted copper conductors, a mica insulating layer arranged outside the twisted copper conductors, and a metal sheath protection layer extruding outside the mica insulating layer. The mica insulation metal sleeve protection high flame retardation fireproof cable is applied to power distribution, lighting, control and alarm systems needing integrity performance of the cable, is special in material, simple in structure, and advanced in technology. The mica insulation metal sleeve protection high flame retardation fireproof cable fully satisfies level requirements regulated by BS6387, is simple in field construction installation technology, long in cable length, and the whole cable is continuous, thus providing excellent electrical performance and machinery performance.
