Referring to fig. 1 and fig. 2, the embodiment of the utility model provides a tensile type motion cable, including insulating protective layer 1, insulating protective layer 1 still is provided with wear-resisting cortex 4 outward, and insulating protective layer 1 is made by butyronitrile material, and wear-resisting cortex 4 is made by polyurethane material, and insulating protective layer 1 makes cable mutual insulation between whole to such insulating layer tensile strength is good, light in weight. The wear-resistant skin layer 4 has good stability, chemical resistance, rebound resilience and mechanical property and smaller compression deformability. Good heat insulation, sound insulation, shock resistance and gas defense performance. The average thickness of the insulating protective sleeve 1 is about 0.38 +/-0.5 mm, and the average thickness of the wear-resistant sheath 4 is about 0.5 +/-0.5 mm. In this case, the flexibility of the cable is preferable. The insulation protective layer 1 is also provided with flame-retardant wires when being manufactured, so that the fire resistance of the cable can be effectively guaranteed.

Including wire 2 and tensile cord 3 in insulating protective layer 1, wire 2 sets up with 3 looks mistake s of tensile cord, all be provided with the tensile 3 between the adjacent wire 2, tensile cord 3 includes tensile steel wire 31 including butyronitrile material protective layer 22 and setting, wire 2 includes copper wire 21 and tensile steel wire 31 including butyronitrile material protective layer 22 and setting, the sheath is also established with the periphery of tensile steel wire to copper wire 21 in the wire 2, the material of sheath also is the butyronitrile material, the sheath is in order to let both mutual insulation, copper wire 21 and tensile steel wire 31 all are provided with many and twist each other around. The setting up of tensile wire 3 is on the one hand to increase wearability and pull resistance, and the contact of isolated wire spare of on the other hand prevents that it from concatenating each other, and butyronitrile material protective layer 22 has softness, fire-retardant, thermal-insulated characteristic, can make the cable drag and the in-process of motion many times when effectively realizing wear resistance, and the security also can be guaranteed. The tensile steel wires in the lead 2 are for reinforcing the strength of the lead, and the tensile wires 3 are for reinforcing the strength of the whole.

The diameter of the copper wire 21 is 0.08mm, and the diameter of the tensile steel wire 31 is 0.1 mm; the copper wire is an annealing anaerobic copper wire, the annealing degree reaches 99.999%, and the copper wire 21 with the structure has high softness and small bending radius, so that the service life is longer.
