The continuous accumulation of large lengths constitutes the production process, and the harm to the production and manufacturing of cables and wires is comprehensive and zoning planning, which involves and harms:

The key to the operation and maintenance of the national standard cable route includes line inspection, maintenance, and solution of shortcomings.

National standard cable products are used in different places, so the role requirements are all aspects, very common. From the perspective of all personnel, its main role is sorted out as follows:

Power supply system selection of cable and wire commodity key empty frame bare cable, medical bus bar (busbar), wire and cable (plastic cable, tinfoil force cable (basically replaced by plastic wire and cable), rubber sheath cable, empty frame insulated wire), branch cable (replace part of the busbar), special cable and electrical equipment with electrical equipment weapons equipment cable and wire.

According to the difference in operation at different operating voltages, cable lines can be roughly divided into five categories:

To improve the recycling technology of waste national standard cable into a cross-type industry of scrap metal recycling and waste plastic recycling, cable and wire can be divided into five categories according to the main use of bare power lines, special cables, electrical equipment weapons and equipment lines, wire and cable and communication cable. They are generally composed of electrical conductors, cable sheaths and protective layers of three parts.
