The application of new technologies involves performance, cost, environmental protection, system safety, and service life. This article will discuss the above problems encountered in the current technological progress of wire and cable from the following 10 aspects.

1. Prevention of termites and rodents-early use of toxic drugs, has now been banned. At present, the mechanical protection type using hard materials is a desirable form.
The application of PBT material-previously only as engineering plastics, is now the main material for optical fiber secondary coating.
3. Promotion of lead-free PVC cable materials-In order to reduce lead pollution, lead-free PVC materials for cables are an inevitable trend.
4. Use of oxygen barrier layer-in order to pass Class B and Class A bunched combustion tests, the cable can adopt a cheap and efficient high-filling extruded oxygen barrier layer.
5. Small size fire-resistant control cable-mica tape quality, winding machine, process parameters are the key to the quality control of the cable.
Automotive low-voltage wires-the most used are still PVC wires, but the development direction is performance specialization, using thin-walled insulation.
7. Five-core cable-domestic use will gradually expand, its structure is diversified, Z-shaped aluminum wire ground wire is recommended.
8. Full-spec fire simulation test-This test proved to be effective and really tested the actual operation of the cable.
9. Expand the application of chlorinated polyethylene-chlorinated polyethylene is superior to chloroprene rubber in terms of performance, price, storage and environmental protection, so it can be replaced. Only in the extrusion of large diameter sheath, still need to be improved in terms of equipment and process.
10. Introduction with branch cable-This is an economical and reliable prefabricated product in the power distribution system, and it will inevitably occupy a place in the domestic middle and high-rise (excluding super high-rise) buildings in the future.
