The invention discloses a
flame-retardant
fireproofing power cable. The
flame-retardant
fireproofing power cable comprises a plurality of conductors,
fireproofing insulating
layers coating the outer sides of the conductors, a
flame-retardant filling
rope, an aluminum plastic composite belt isolating layer and a flame-retardant jacket layer, wherein the conductors and the fireproofing insulating
layers form insulating cable cores, the aluminum plastic composite belt isolating layer wraps the outside of a cabling structure which is formed by a plurality of insulating cable cores in a twisting mode, the flame-retardant filling
rope is filled into the gap between the fireproofing insulating
layers and the aluminum plastic composite belt isolating layer, and the flame-retardant jacket layer is arranged on the outer surface of the aluminum plastic composite belt isolating layer. According to the flame-retardant fireproofing
power cable, a combined structure of the fireproofing insulating layers, the aluminum plastic composite belt isolating layer and the flame-retardant jacket layer is adopted, an original
mica tape lapping fire resisting structure is replaced, the production processes of the cable are reduced, the flame-retardant fireproofing performance of the cable is enhanced, staff loss and property loss under a fire environment are effectively lowered, the using safety performance of the power cable is improved, the service life of the cable is prolonged.
