1. Bare wires and bare conductor products
The main features of this category of products are: pure conductive metal, no insulation and sheath, such as steel core aluminum stranded wire, copper-aluminum busbar, electric locomotive wire, etc.; processing technology is mainly pressure processing, such as melting, rolling, drawing The products are mainly used in suburbs, rural areas, user main lines, switch cabinets, etc.
2. Power cable
The main features of this type of product are: squeeze (wind) the insulation layer outside the conductor, such as overhead insulated cables, or stranded several cores (corresponding to the phase, neutral and ground wires of the power system), such as overhead insulated cables with more than two cores , Or add a sheath layer, such as plastic/rubber wire and cable. The main process technologies include drawing, stranding, insulation extrusion (wrapping), cable formation, armoring, sheath extrusion, etc. The different process combinations of various products have certain differences.
The products are mainly used in the transmission of strong electric energy in power generation, distribution, transmission, transformation, and power supply lines, with large current (tens of amperes to several thousand amperes) and high voltage (220V to 500kV and above).
, Wire and cable for electrical equipment
The main features of this type of products are: a wide range of varieties and specifications, a wide range of applications, with more voltages of 1kV and below, and constantly deriving new products in the face of special occasions, such as fire-resistant cables, flame-retardant cables, low smoke and halogen free Smoke and low halogen cables, termite-proof, mouse-proof cables, oil-resistant/cold-resistant/temperature-resistant/wear-resistant cables, medical/agricultural/mining cables, thin-walled cables, etc.
4. Communication cables and optical fibers (a brief introduction)
With the rapid development of the communications industry in the past two decades, products have also developed at an astonishing speed. From the simple telephone and telegraph cables in the past, it has developed to thousands of pairs of voice cables, coaxial cables, optical cables, data cables, and even combined communication cables.
The structure size of this kind of product is usually small and uniform, and the manufacturing precision is high.
5. Magnet wire (winding wire)
Mainly used in various motors, instruments, etc.
Derivatives/New Products of Wire and Cable
Derivatives/new products of wire and cable are mainly due to different application occasions, different application requirements, convenience of equipment and requirements of equipment cost reduction, etc., and the use of new materials, special materials, or changing product structure, or improving process requirements, or different Varieties of products are combined.
Use different materials such as flame-retardant cables, low-smoke zero-halogen/low-smoke abc cables, termite-proof, mouse-proof cables, oil/cold/temperature-resistant cables, etc.;
Change the product structure such as: fire-resistant cable, etc.;
Improve process requirements such as: medical cables, etc.;
Combination products such as OPGW, etc.;
It is convenient to install and reduce equipment costs, such as prefabricated branch cables.
