The core wire 10 includes a conductor 11, a polyester tape layer 12 wrapping the conductor 11, and a chlorinated polyethylene rubber insulation layer 13 covering the polyester tape layer 12. The polyester tape layer 12 protects the copper wire from oxidation and facilitates the peeling between the chlorinated polyethylene rubber insulation layer 13 and the conductor 11. The gap between the plurality of core wires 10 is filled with a filler 50 to improve the strength of the overall cable. The shielding layer 30 is wound on the wrapping layer 20 to provide mechanical strength to the cable, effectively buffer the internal stress of the cable twisting, ensure the normal operation of the cable in the twisted state, meet the test of 15000 times of reciprocating bending without open circuit, short circuit, and crack, and meet the use requirements of mobile electrical equipment in complex working conditions.

[0018] Specifically, the shielding layer 30 is formed by interlaced winding of tin-plated alloy copper wire and copper foil tape. The thickness of the shielding layer 30 is 0.3-0.5mm by interlaced winding of tin-plated alloy copper wire and copper foil tape on the wrapping layer 20. Preferably, the thickness of the shielding layer 30 is 0.5mm, thereby improving the tensile strength and torsional bending resistance of the overall cable. Meanwhile, the shielding layer 30 formed by interlaced winding of tin-plated copper wire and copper foil also has the function of shielding external interference, ensuring the normal operation of the equipment.

The gap between the plurality of core wires 10 is filled with a filler 50, which is filled with hemp rope, to further ensure the roundness of the cable core. The plurality of core wires 10 and the filler 50 are then wrapped and fixed by the wrapping layer 20, so that the internal structure of the cable is not loose and the stability of the cable structure is improved. The wrapping layer 20 is formed by wrapping non-woven fabric.

[0021] Specifically, the insulation layer of the core wire 10 is made of irradiated chlorinated polyethylene rubber material. The thickness of the chlorinated polyethylene rubber insulation layer 13 is 1.0-1.2mm, and preferably 1mm. The chlorinated polyethylene insulation layer 13 protects and insulates the cable core inside the cable, reduces the harm of the cable to personnel, and makes the core wire 10 have excellent ozone and heat extension resistance, insulation resistance, aging resistance, and atmospheric aging resistance, etc. excellent characteristics, and does not need to use the steam continuous sulfur process, thereby avoiding the problem of scorching caused by the steam continuous sulfur process.

[0022] Further, the thickness of the chlorinated polyethylene rubber sheath layer 40 is 1.5-2.0 mm, and the preferred thickness is 1.8 mm. The chlorinated polyethylene rubber sheath layer 40 uses irradiated chlorinated polyethylene rubber, has good heat resistance and insulation performance, can maintain high flexibility at high and low temperatures, effectively buffers the internal stress of the cable under torsion, ensures the normal operation of the cable under torsion, and prevents the internal components of the cable from being corroded by external chemicals, thereby preventing the cable from being damaged, so that the cable meets the tensile strength, elongation at break, heat aging resistance, heat extension, and oil immersion performance tests, and meets the SE4 sheath performance indicators of GB / T5013-2008.
