  Wire and cable for electrical equipmentIt is the main product with the most widely used, the most variety, the most yield and the most complex process in each major category. The number of varieties accounts for about 60% of the total number of wires and cables. Production is about 30%. The name of this category is "rubber, plastic insulated wire and cable" (5,60) "various industrial cables" (6,70) and so on. Before filling in the "Wire and Cable Manual", the official name of "wire and cable for electrical equipment" has been recognized by the industry. The definition of large-scale products is that on the final switch equipment, various electrical equipment and instruments are directly connected with wires and cables to transmit power. Electrical equipment with wire and cable all kinds of electrical equipment internal connection installation line; in the signal, measurement, control system, wire and cable are collectively referred to as electrical equipment with wire and cable.


What are the classification of wires and cables for electrical equipment?Power cable factory, Yanggu cable factoryTo explain for you.

Bare wire body products

The main features of these products are pure conductor metal, insulation and sheath layers (such as steel core aluminum stranded wire, copper aluminum bus bar, electric locomotive line, etc.). The processing technology is mainly smelting, rolling, pulling, stranding/extrusion and other pressure processing. Products are mainly used in the suburbs, rural areas, users of the main line, switch cabinets and so on.

Power Cord

The main feature of these products is to braid (detour) insulating layers on conductors such as overhead insulated cables with more than 2 cores, such as overhead insulated cables or plastic/rubber sheathed wires and cables, and several cores are twisted (corresponding to the phase and neutral lines of the power system And ground wire), or add a sheath layer. The main process technology includes pulling, twisting, insulation protrusion (winding), cable, gloves, protective layer protrusion, etc., according to the process combination of each product has certain differences.

Electrical equipment with wire and cable is mainly used for sending, distribution, transportation, change, power transmission on the power line, for the current through the large (tens of amperes to thousands of amperes), high voltage (220V to 35kV above).

The main characteristics of wires and cables for electrical equipment are diversity, different scope of application, voltage use below 1kV, fire-resistant cables, flame-retardant cables, low-extension halogen/low-extension halogen cables, termite-proof, mouse-proof cables, oil-resistant/cold-resistant/temperature-resistant/wear-resistant cables and other special circumstances continue to derive new products.

Communication cables and optical fibers

With the rapid development of the communication industry, from the past simple telephone and telegraph cables to thousands of horse cables, coaxial cables, optical cables, data lines, and even communication cables. These product structure size is usually small, uniform, high precision manufacturing.

Right Good Line

Winding wire is a conductive metal wire with an insulating layer around which an electrical coil or winding is wound. When acting, a magnetic field is generated by current or a magnetic line of force is cut off to generate an induced current, which realizes the conversion of electric energy and magnetic energy and becomes an electromagnetic line.
