Preferably, a steel wire mesh layer is arranged between the flame-retardant layer and the shielding layer, the steel wire mesh layer is wrapped inside the flame-retardant layer, and the shielding layer is wrapped inside the steel wire mesh layer.
Preferably, an insulating support is arranged inside the filling layer.
Preferably, the insulation support comprises six insulation plates with the same structure, the six insulation plates are distributed in an annular array, and the wire harnesses are respectively located between two adjacent insulation plates.
Preferably, the insulating support is made of rubber.
The invention has the beneficial effects that: through setting up heat-resisting fire-retardant layer, make this cable can effectually be applicable to high temperature environment, setting through the steel wire net layer, make this cable can its wear resistance of effectual improvement, and can improve the power transmission and the signal transmission quality of this cable through the setting of shielding layer, through set up the filling layer and set up insulating support in the filling layer in its inside, make its inside pencil separately place, each other does not influence, keep its stability of using, and can make this cable have the anti extrusion barrier propterty of certain degree, keep normal power transmission and signal transmission quality, suitable using widely.
