Abstract
The utility model discloses a flame-retardant power cable. The power cable is formed by a fluorinated ethylene propylene outer sheath, a tin-plated copper wire braided shielding layer and cable cores. The tin-plated copper wire braided shielding layer extrudes four power wire cores so as to form the cable core. A polyvinyl chloride insulation layer extrudes three insulation wire cores so as to form the power wire core. A silicone rubber insulation layer extrudes two silver-plated copper wire stranded conductors and two aluminum alloy conductors so as to form the insulation wire core. An intermediate portion of the four power wire cores is provided with a nanometer carbon fiber inner core. A flame-retardant ceramic powder filling layer is arranged in a gap of the cable cores. The fluorinated ethylene propylene outer sheath wraps the cable cores. The cable is suitable for high voltage line and power line laying and has the characteristics that the weight is light; a shielding property is good; an anti-interference performance is good; the structure is stable; flame-retardation, fireproof, anti-tensile and anti-shearing performances are realized.
Description
