Abstract
The invention discloses a flame-retardant power cable. The flame-retardant power cable is composed of an FEP over sheath, a tinned-copper-wire-braided shielding layer and a cable core. The cable core is formed by wrapping the tinned-copper-wire-braided shielding layer on four power wire cores in an extruding mode, each power wire core is formed by wrapping a PVC insulating layer on three insulting wire cores in an extruding mode, and each insulting wire core is formed by wrapping a silicone rubber insulating layer on two silver-plated cooper wire stranded conductors and two aluminum alloy conductors in an extruding mode. A nanometer fiber inner core is arranged in the middle of the four power wire cores. Flame-retardant ceramic powder packing layers are arranged in gaps in the cable core. The FEP over sheath is wrapped on the cable core. The flame-retardant power cable is suitable for high-voltage power line cable laying and has the advantages of being light in weight, good in shielding performance, good in anti-interference performance, stable in structure, fireproof and resistant to stretching and shearing.
Description
Technical field
