It is provided with one layer of filled layer on the inside of screening braid, and is enclosed with a strata vinyl chloride protective layer on the inside of filled layer, and is poly-
Multiple cables core are installed, the outer layer covers of the cable core have a layer insulating, and insulating layer on the inside of vinyl chloride protective layer
Inside be provided with one layer of conductor shield, aluminium core is installed on the inside of the conductor shield.
Preferably, the cross-sectional shape of the cable body is circle.
Preferably, the cable core is equipped with more, and multi-cable core is separated by carbon fiber layer.
Preferably, the aluminium core is connected in a manner of rotating winding.
Preferably, one layer of inner protective layer is provided between the filled layer and polyvinyl chloride protective layer.
Preferably, it is pasted between each protective layer of the cable body with glue.
Compared with prior art, the utility model has the beneficial effects that firstly, in this aluminium core polyvinyl chloride insulation polychlorostyrene second
The outer layer of each cable core of alkene sheath fireproof power cable is all enclosed with fire lagging, so that the fire resistance effect of cable mentions
Height, fire lagging can effectively prevent cable and a large amount of dense smoke of after-combustion generation occur in fire and contains hazardous substance
The hazardous material harm to the human body released when burning and the corrosion to equipment, secondly, the outer layer in cable core is equipped with one layer of carbon
Fibrous layer, carbon fiber have very strong ductility, can be very good that cable core is protected not to be damaged in cable folding, most
Afterwards, polyvinyl chloride protective layer is provided on the inside of fire lagging, under voltage rating condition of power supply, polyvinyl chloride protective layer
Insulating reliability it is big, and the flame retardant effect of polyvinyl chloride protective layer is also fine, and then extends the service life of cable.
