Problems solved by technology

[0003] In the existing cable structure, in order to improve the oil resistance of the cable, an oil-proof film is often added to the surface of the cable, but the oil-proof film after the secondary treatment is not uniformly connected to the cable, and it is easy to fall off, especially in the environment of power operation. It is more susceptible to corrosion and causes damage to the cable structure, affecting normal production work
For the bending resistance process of the cable, it is often only passive to improve the material of the cable to improve the bending resistance of the cable, but the price of this approach is that the price of the cable is greatly increased, and the comprehensive application cost is seriously increased. In the industry, in order to reduce costs, a combined cable structure is often used, but this structure causes the integrity of the cable to be destroyed, and the electrical properties such as the resistance of the cable at the connection point change, resulting in a decrease in the conductivity of the cable.
Moreover, on the basis of the existing cable structure, the production and preparation methods of the cable are relatively complicated, and it is difficult to achieve rapid and economical preparation.

Abstract

The invention discloses an oil-resistant and bend-resistant machinery cable structure and preparation method of the same, including conductor lines which are spirally connected in hinge to form a monomer. The outer surface of the conductor lines are successively coated with a silica shielding layer, a cellosilk layer, a PVC film and a rubber layer. The outer surface of the monomer is coated with a two-dimensional cellosilk layer. And semiconducting silicone rubber layers are both filled between the two-dimensional cellosilk layer and the monomer. The outer surface of the two-dimensional cellosilk layer is successively provided with a nonwoven fabric layer and a silicone rubber sheath, and the nonwoven fabric layer and the silicone rubber sheath are both provided with PVC films. After fiber drawing, coating and plastic sucking, the oil-resistant and bend-resistant mechinery cable structure and preparation method of the same has the advantages of improving cable's corrosion resistance and bending resistance.

Description

technical field [0001] The invention relates to the field of cable preparation technology, in particular to an oil-resistant and bending-resistant mechanical equipment cable structure and a preparation method. Background technique [0002] With the development of modern electronic technology, a variety of electrical equipment has gradually filled people's production and life, and a large number of electrical equipment requires a large number of supporting cables. In actual industrial production, the working environment faced by industrial equipment is very severe. The most important thing is to be in the environment of oil pollution for a long time, and in some power electrical equipment, the working cables not only have to face the erosion accidents of the external environment, but also need to face The bending phenomenon caused by the movement of power equipment, and these two factors are the main factors that cause damage to the cable structure in the actual application p...
