Further, one of the reinforcing cords is disposed immediately adjacent one of the conductors.

Furthermore, the insulating layer is a halogen-free low-smoke polyolefin insulating layer.

Furthermore, the conductor is of a structure of a plurality of annealed oxygen-free tinned copper wire stranded conductors.

Further, the filler is a polypropylene rope.

Further, the weaving layer is an aramid fiber weaving layer.

Further, the outer sheath is a thermoplastic polyurethane elastomer rubber sheath.

Compared with the prior art, an environmental protection flexible cable have following advantage:

1) in the cable structure, the design of weaving the interlayer by the reinforcing rope belt can enable the cable to be subjected to long-time winding dragging movement, and the cable structure has extremely excellent tension resistance, insulation and pressure resistance, winding and pressure resistance, wear resistance and the like. The aramid yarn braided layer has tensile and anti-torsion characteristics, and can resist damage of tensile force to a cable and damage of an internal structure caused by spiral generated by torsion force in a cable bending and winding process.

2) The product has the excellent performances of wear resistance, tensile resistance, aging resistance, flexibility, bending resistance, weather resistance, oil resistance, low temperature resistance, flame retardance, small bending radius, tensile resistance and the like, solves a series of performance problems of cracking, easy breakage, easy aging and the like in the wear-resistant service environment of the common flexible cable, and prolongs the service life of the cable.
