Yunnan cable manufacturers: wire and cable products are mainly divided into five categories

1. Bare wire and bare conductor products

The main features of this type of product are: pure conductor metal, no insulation and sheath, such as steel core aluminum stranded wire, copper aluminum bus bar, electric locomotive wire, etc. The processing technology is mainly pressure processing, such as melting, rolling, stretching, twisting/compression twisting, etc. Products are mainly used in the suburbs, rural areas, users of the main line, switch cabinets and so on.

2. Power cable

The main features of this type of product are: squeezing (winding) a layer of insulation around the conductor, such as overhead insulated cables, or stranding several cores (corresponding to the phase line, zero line and ground line of the power system), such as overhead insulated cables with more than two cores, or adding a layer of sheath, such as plastic/rubber sheathed wire and cable. The main process technologies include drawing, stranding, insulation extrusion (winding), cable forming, armor, sheath extrusion, etc. There are some differences in the different process combinations of various products. The products are mainly used for the transmission of high-voltage electric energy in power generation, distribution, transmission, transformation and power supply lines, with large current (tens of amperes to thousands of amperes) and high voltage (220V to 500kV and above).

3. Yunnan cable manufacturers share wire and cable for electrical equipment

The main features of this type of product are: many varieties and specifications, a wide range of applications, and more voltages below 1kV. 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, termite-proof cables, rodent-proof cables, oil-resistant/cold-resistant/temperature-resistant/wear-resistant cables, medical/Agricultural/mining cables, thin-walled wires, etc.

4. Communication cable and optical fiber

In the past two decades, with the rapid development of the communications industry, Yunnan cable manufacturers have found that their products have also developed at an alarming rate. From the simple telephone and telegraph cables in the past, to thousands of pairs of telephone cables, coaxial cables, optical cables, data cables, and even combination communication cables. Such products are usually small in size, uniform in structure and high in manufacturing precision.

5. Electromagnetic wire (winding wire)

Mainly used for various motors, instrumentation, etc.
