Specific embodiment
Embodiment
Referring to Fig. 1, a kind of wear-resisting weather-proof water proof fire retardant power cable of the present embodiment, including more core parts, filled layers
3, waterproof layer 4, fire-retardant sheath 5, armor 6, flame-retardant layer 7, bonding waterproof layer 8 and fire-retardant outer jacket 9, filled layer, waterproof layer,
Fire-retardant sheath, armor, flame-retardant layer, bonding waterproof layer and fire-retardant outer jacket are set gradually from the inside to the outside, and more core parts are in
Circular array column-shaped is distributed in the periphery of filled layer central axis.
Wherein, core part includes cable core 1 and the insulating layer 2 for wrapping up cable core, and cable core 1 is twisted for multiple conducting wires
