The cable cores are arranged in two layers, one cable core is arranged in the center, and a cotton-filled rope is woven outside the cable core, and the outer layer cable core is arranged around the central cable core woven with the cotton-filled rope.

The quantity of the cotton filling rope corresponds to the quantity of the outer layer cable core, and the cotton filling rope is located in the gap between the outer layer cable core and the middle cable core.

The diameter of the tinned copper single wire is less than or equal to 0.3 mm.

The insulating layer is flame-retardant ethylene-propylene rubber.

The inner sheath and the outer sheath are flame-retardant and oil-resistant neoprene rubber.

The beneficial effects produced by the utility model are:

1. The cotton support rope, cotton bearing rope, cotton filling rope and the outer covering insulation layer of the utility model play a tensile role together, and do not conduct electricity. Do not damage each other and increase the movement resistance, and the core structure is stable.

2. The conductors of the utility model use single wires not greater than 0.3mm, and are made of tinned copper wire conductors through the bundle winding process, so that the anti-drag ability and flexibility of the cable are improved, and at the same time, the cotton load-bearing rope and cotton-filled The rope is also tensile and flexible, allowing the entire cable to be wound onto reels and drums.

3. A structure of the utility model is that one cotton load-bearing rope and six tinned copper wire insulated wire cores are twisted to form a cable core, wherein the cotton load-bearing rope is located in the center. A layer of inner sheath is tightly extruded outside the cable core to make a set of control wire core groups, and then a total of 7 groups of control wire core groups are twisted together in an arrangement of 1+6, and a layer of outer sheath is tightly extruded Sheath in which 6 cotton-filled cords are braided over a centrally placed control core set. This structure makes the cable structure compact, and every 7 cores form a whole group, which can effectively avoid the risk of the core being pulled out due to inconsistent force on the insulated core during the movement of the cable. In addition, the cotton-filled rope is braided to increase friction and ensure the stability of the entire cable core.

4. Both the inner sheath and the outer sheath of the utility model are made of flame-retardant and oil-resistant neoprene rubber material, wherein the inner sheath mainly tightens the insulated wire cores of each group inside, and the outer sheath tightens the inner core of the entire cable. The wire core group is tightened, making the overall structure of the cable more compact and stable. At the same time, the material of the inner and outer sheaths does not have oil absorption, which completely solves the problem of expansion and cracking of the cable when it is used in an oily environment.

Therefore, the utility model can meet the requirements of use on oily ground, winding and moving occasions, and is very suitable for the control connection of electrical equipment in similar environments.

In order to describe the technical features and practical effects of the present utility model in detail, and to realize them according to the content of this specification, the implementation of the present utility model will be further described below in conjunction with the accompanying drawings.
