1, bare wire and bare conductor products
The main characteristics of this type of products are: pure conductor metal, no insulation and sheath layer, such as steel-core aluminum stranded wire, copper and aluminum bus, electric locomotive line, etc. processing technology is mainly pressure processing, such as melting, calendering, drawing, stranding/pressing stranded, etc. products are mainly used in suburban, rural, user main line, switch cabinets.
2. Power cable
The main characteristics of this type of product is: in the outside of the conductor extrusion (around) the insulation layer, such as aerial insulated cable, or a few core stranded (corresponding to the power system phase, 0 and ground), such as two cores above the aerial insulated cable, or additional sheath layer, such as plastic/rubber sheathed wire and cable.
The main process technology has drawn, stranded, insulated extrusion (wrapping), cable, armored, protective layer extrusion, and various products of different process combinations have a certain difference.
Products are mainly used in hair, distribution, transmission, change, power supply line of strong electrical power transmission, through the large current (dozens of to thousands of amps), High voltage (220V to 500kV and above).
3, electrical equipment with wire and cable
The main characteristics of such products are: variety of specifications, wide range of applications, the use of voltage in 1kV and below more, in the face of special occasions continue to derive new products, such as fire-resistant cable, flame-retardant cable, low smoke halogen-free/low-smoke low halogen cable, anti-termite, anti-mouse cable, oil/cold/temperature/wear cable, medical/agricultural/mining, thin-walled wire, etc.
4, communication cables and optical fiber (brief introduction)
With the rapid development of the communication industry in the past more than 20 years, the product also has the astonishing development speed. From the past simple telephone telegraph cable developed to thousands of pairs of words cable, coaxial cable, optical cable, data cable, and even a combination of communication cables.
