Embodiment 1
[0020] (1) Manufacture the central reinforcement core 1, the insulated wire core bundle 2, and the peripheral reinforcement core 3 respectively;
[0021] The manufacturing steps of the central reinforcing core 1 are as follows: the synthetic yarns of nylon, cotton fiber and acrylic fiber are twisted into soft high-strength strands, and then the high-strength strands are re-twisted on the outer periphery of the central lead drop wire 1a to form the central synthetic yarns. Covering layer 1b; seven central lead drop wires 1a with central synthetic wire covering layer 1b are formally twisted into the inner core of central reinforcing core 1 in the form of concentric circles; The central aramid yarn braiding layer 1c is composed of 0.3mm aramid yarn weaving, and the weaving density is 80%;
[0022] The manufacturing steps of the insulated wire core bundle 2 are as follows: use insulating rubber to extrude the conductor insulation layer 2d on the outer periphery of the core wire co...
Embodiment 2
[0038] (1) Manufacture the central reinforcement core 1, the insulated wire core bundle 2, and the peripheral reinforcement core 3 respectively;
[0039] The manufacturing steps of the central reinforcing core 1 are as follows: the synthetic yarns of nylon, cotton fiber and acrylic fiber are twisted into soft high-strength strands, and then the high-strength strands are re-twisted on the outer periphery of the central lead drop wire 1a to form the central synthetic yarns. Covering layer 1b; seven central lead drop wires 1a with central synthetic wire covering layer 1b are formally twisted into the inner core of central reinforcing core 1 in the form of concentric circles; The central aramid yarn braiding layer 1c is composed of 0.4mm aramid yarn weaving, and the weaving density is 85%;
[0040] The manufacturing steps of the insulated wire core bundle 2 are as follows: use insulating rubber to extrude the conductor insulation layer 2d on the outer periphery of the core wire co...
Embodiment 3
[0056] (1) Manufacture the central reinforcement core 1, the insulated wire core bundle 2, and the peripheral reinforcement core 3 respectively;
[0057] The manufacturing steps of the central reinforcing core 1 are as follows: the synthetic yarns of nylon, cotton fiber and acrylic fiber are twisted into soft high-strength strands, and then the high-strength strands are re-twisted on the outer periphery of the central lead drop wire 1a to form the central synthetic yarns. Covering layer 1b; seven central lead drop wires 1a with central synthetic wire covering layer 1b are formally twisted into the inner core of central reinforcing core 1 in the form of concentric circles; The central aramid yarn braiding layer 1c is woven with 0.35mm aramid yarn, and the weaving density is 82%;
[0058] The manufacturing steps of the insulated wire core bundle 2 are as follows: use insulating rubber to extrude the conductor insulation layer 2d on the outer periphery of the core wire conductor ...
