Main classification of wire and cable products
1. Bare wire and bare conductor products
The main features of this product are pure conductor metal, no insulation and sheath layer, such as steel core aluminum stranded wire, copper-aluminum busbar, electric locomotive line, etc.; processing technology is mainly pressure processing, such as smelting, rolling, pulling System, stranding/tightening stranding, etc.; 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 extrusion (winding) insulation on the outer conductor, such as overhead insulated cable, or stranding (corresponding to the phase, neutral, and ground of the power system), such as overhead insulated cables with two cores or more, or add a jacket layer, such as plastic/rubber sheathed wire and cable. The main process technologies include drawing, stranding, insulation extrusion (winding), cable-forming, armoring, and sheath extrusion. The different process combinations of various products have certain differences.
The products are mainly used for the transmission of strong electric energy in the transmission, distribution, transmission, transformation, and power supply lines. The current passing through is large (tens of amps to several thousand amps) and the voltage is high (220V to 500kV and above).
3. Wire and cable for electrical equipment
The main features of this type of product are a wide variety of specifications, wide application range, use voltages of 1kV and below, and new products such as fire-resistant cables, flame-retardant cables, low-smoke halogen-free/low Smoke low halogen cables, termite prevention, mouse cable, oil/cold resistant/temperature resistant/wear resistant cable, medical/agricultural/mineral cable, thin wall wire, etc.
4, communication cable and optical fiber (the company does not currently produce such products, so a brief introduction)
With the rapid development of the communication industry in the past two decades, the products have also experienced phenomenal growth. From the simple telephone telegraph cable of the past to thousands of pairs of cable, coaxial cable, optical cable, data cable, and even combined communication cable.
The structural dimensions of such products are generally small and uniform, and manufacturing precision is required.
Face the socket and press the correct connection of the left zero (N) and right fire (L) to the ground (E). Firewire-L (red, yellow, blue), neutral-N (blue or black), ground-E (yellow-green). Three-phase four-wire transmission of power in a low-voltage grid, three of which are phased (Fire line) rep...
