Problems solved by technology

In the actual use process, it is found that the cable moves with the movement of the equipment, and there is a lot of oil on the ground. There are usually two problems in the use of ordinary cables. One is that the central insulating core of the cable often breaks, and the other is that The oil resistance of the cable is very poor. The outer sheath of the cable swells and cracks after being soaked in oil on the ground on site. The problem seriously affects the normal use of the cable

Embodiment 1

[0026] refer to figure 1 , is a specific structure of the oil-resistant and drag-resistant reel control cable of the present invention. specific:

[0027] Firstly, first use the tinned copper single wire 3 of no more than 0.3 mm to be wound on the cotton support rope 1 to make a tinned copper wire conductor; extrude the insulating layer 4 around the tinned copper wire conductor to make a tinned copper wire conductor. Copper wire insulated core.

[0028] Then, a cotton load-bearing rope 2 and 6 tinned copper wire insulated wire cores are twisted to form a control wire core group, in which the cotton load-bearing rope 2 is located in the center; and a layer of inner sheath is tightly extruded outside the control wire core group 5. Make the cable core.

[0029] Then, a total of 7 cable core groups are arranged in two layers according to the arrangement of 1+6. Among them, 6 cotton-filled ropes 6 are braided outside the cable core placed in the center; and the cotton-filled rop...

Abstract

The invention provides an oil-proof and dragging-resistant coiled control cable. The oil-proof and dragging-resistant coiled control cable comprises a plurality of cable cores twisted together and an outer sheath wrapped on the peripheries of the cable cores, wherein each of the cable cores sequentially comprises a cotton bearing rope, a plurality of insulating cable cores and an inner sheath from the interior to the exterior, and the cable cores are made through positioning the cotton bearing ropes in the centers, arranging the insulating cable cores around the cotton bearing ropes for one circle, twisting the cotton bearing ropes and the insulating cable cores together and tightly wrapping the inner sheaths on the peripheries through extruding; the insulating cable cores are made through winding tinned copper single wire harnesses on cotton support ropes and wrapping insulating layers on the peripheries through extruding. The center and all the layers of the cable are designed according to a dragging-resistant structure, so that the whole cable has excellent dragging-resistant performance, oil-proof performance and winding performance, and meets the connecting use of a control system for mobile electric appliances in a similar environment.

Description

technical field [0001] The invention relates to cables, in particular to an oil-resistant and drag-resistant reel control cable, which can be widely used in electrical control connections of metallurgical and mechanical equipment, especially for electrical control connections of equipment with reels and reels. Background technique [0002] In the metallurgical industry equipment, there are more mobile equipment, such as mobile lathes. The cables of these electrical equipment are quite special. There is a reel or reel for storing cables on the mobile lathe. One end of the cable is connected to the bottom of the reel, and the other end is connected to the electrical control equipment. In the actual use process, it is found that the cable moves with the movement of the equipment, and there is a lot of oil on the ground. There are usually two problems in the use of general cables. One is that the central insulating core of the cable often breaks, and the other is that The oil r...
