The main features of the wire and cable products are: pure metal conductor, no insulation and sheathing layer, such as ACSR, copper and aluminum bus, electric locomotives lines; the main processing pressure processing, such as smelting, rolling , drawing, stranding / stranded pressed; products are mainly used in suburban, rural, user mainline, switch cabinets.

Wire and cable products categories are thousands of applications in all walks of life. They are always used in two ways, one is the transmission current, one is the transmission signal. Technical performance transmission cables current class is the most important control conductor resistance, pressure resistance; class technical performance indicators signal transmission cable transmission performance is the primary control - characteristic impedance, attenuation and crosstalk, etc. Of course, also the main transmission signal by current (electromagnetic waves) as a carrier, and now with the development of science and technology can be used as a carrier to transmit light waves.
