Cable process flow

The manufacturing of wires and cables is completely different from that of most mechanical and electrical products. Mechanical and electrical products usually adopt the method of assembling another part into a part, and then assembling multiple parts into a single product. The products are measured by the number of sets or pieces. The basic unit of measurement of wire and cable is length. All wires and cables are made of wire and cable products by adding insulation, shielding, cabling, protective layer, etc. layer by layer on the periphery of the conductor. The more complex the product structure is, the more layers are superimposed.

Cable storage method

If the cable is to be stored for a long time, it shall be placed according to the location of the cable. 1. Under the eaves. The cable can be used only when it is not directly exposed to sunlight or ultra-high temperature. It is recommended to use pipeline. 2. On the outer wall. Avoid direct sunlight on the wall and man-made damage.

Cable safety requirements

When the cables cross each other, the high-voltage cable shall be under the low-voltage cable. 1. When cables cross each other, the high-voltage cable shall be under the low-voltage cable. If one of the cables is protected by a pipe or separated by a partition within 1m before and after the intersection, the minimum allowable distance is 0.25m. 2. When the cable approaches or crosses the thermal pipeline, if there are thermal insulation measures, the minimum distance between parallel and cross is 0.5m and 0.25m respectively.
