Bare wire body products
The main characteristics of this type of product are: pure conductor metal, without insulation and sheath layer, such as steel-cored aluminum stranded wire, copper-aluminum busbar, electric locomotive line, etc; The processing technology is mainly pressure processing, such as melting, rolling, drawing, stranding/compression stranding, etc; Product owner
Wire and cable
The main features of this type of product are: extrude (wrap) the insulation layer outside the conductor, such as overhead insulated cable, or stranded several cores (corresponding to the phase line, zero line and ground wire of the power system), such as overhead insulated cable with more than two cores, or add a sheath layer, such as plastic/rubber sheathed wire and cable. The main process technologies include drawing, stranding, insulation extrusion (wrapping), cabling, armor and sheath extrusion, etc. The different process combinations of various products have certain differences.
The product is mainly used for the transmission of strong electric energy in the power generation, distribution, transmission, transformation and power supply lines, with large current (tens of amperes to thousands of amperes) and high voltage (220V to 35kV and above).
Wire and cable for electrical equipment
Flat cable (3 pieces)
The main characteristics of these products are: a wide variety of specifications, a wide range of applications, and a wide range of voltages of 1kV and below. In the face of special occasions, new products are constantly derived, such as fire-resistant cables, flame-retardant cables, low-smoke halogen-free/low-smoke halogen-free cables, anti-termite, anti-mouse cables, oil-resistant/cold-resistant/temperature-resistant/wear-resistant cables, medical/agricultural/mining cables, thin-walled wires, etc.
Communication cable and optical fiber
With the rapid development of the communication industry, from simple telephone and telegraph cables in the past to thousands of pairs of telephone cables, coaxial cables, optical cables, data cables, and even combined communication cables. The structural dimensions of these products are usually small and uniform, and the manufacturing accuracy requirements are high.
Winding wire
Winding wire is a kind of conductive metal wire with insulating layer, which is used to wind the coil or winding of electrical products. When it works, the magnetic field is generated by the current, or the induced current is generated by cutting the magnetic line of force to realize the conversion of electric energy and magnetic energy, so it is also called electromagnetic line.
