Description

Technical Field

[0001] The utility model relates to the technical field of electric wires and cables, in particular to a wear-resistant electric wire and cable. Background Art

[0002] Cable is a device for transmitting electric energy or signals. It is usually a rope-like cable formed by twisting several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating covering. The vast majority of wire and cable products are products with exactly the same cross-sectional (cross-sectional) shape (ignoring errors caused by manufacturing) and are in the form of long strips. This is determined by the characteristics of being used as a circuit or coil in a system or equipment. After a long period of use, the exterior of the wire and cable in the prior art is inevitably severely worn. In response to this, we propose a wear-resistant wire and cable. Utility Model Content
