Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables, which can be defined as one or more insulated cores, and their respective coatings, total protective layers and outer sheaths. Cables may also have additional uninsulated conductors.

The utility model discloses an anti-shear multilayer cable, in which a flexible steel wire mesh is provided in the protective layer, which can prevent the cable from being cut by shearing and improve the protection performance of the cable. Since the inner surface of the cable is provided with an ABS plastic layer, a vinyl resin layer and an epoxy resin layer, the anti-corrosion performance of the cable can be effectively improved. The semi-annular block is sleeved on the outer surface of the cable. At this time, the arc-shaped connecting block will firmly clamp the semi-annular block on the outer surface of the cable through the elastic force of the elastic rope, and then the fixing bolt is turned to fix the semi-annular block on the other side with the arc-shaped connecting block. Finally, people move the cable through the control rod, which brings better prospects for use.

[0004] Although the existing anti-shear multi-layer cables can solve the problem that the cables are easily cut during use, thereby reducing the efficiency of cable use and being inconvenient for people's operation, and when people pull the cables, their hands are prone to slipping, which reduces people's user experience, but generally when the cables are buried in the soil, they are often faced with the situation of being cut and damaged. Although there are anti-shear structures at present, they have no effect at all when the work is frequently cut by mistake.

[0005] Therefore, in order to solve the above problems, an anti-shearing cable is proposed. Utility Model Content
