Main categories of wire and cable products
The design of wire and cable products can be mainly divided into five categories: 1. Bare wire and bare conductor products The main development characteristics of this type of information product are: pure conductors are made of metal, without insulation and sheath, such as steel core aluminum stranded wire, copper aluminum busbar, electric locomotive wire, etc.; the processing technology is mainly through pressure processing, such as melting, rolling, drawing, twisting/tight twisting, etc. The product design can be mainly used for suburban areas, rural areas, user management trunk lines, switch cabinets, etc.
Wire and cable product design can be mainly divided into five categories:
1. Bare wires and conductors
The main development characteristics of this type of information product are: pure conductors are made of metal, without insulation and sheathing, such as steel-core aluminum stranded wire, copper-aluminum busbars, electric locomotive wires, etc.; the processing technology mainly uses pressure processing, such as melting, rolling, drawing, twisting/tight twisting, etc. The product design can be mainly used for suburban areas, rural areas, user management trunk lines, switch cabinets, etc.
2. Power cables
The main characteristics of this type of product are: extrusion (winding) wires, such as overhead line insulation level cables, or multi-core stranded wires (corresponding phase wires, neutral wires, ground wires), such as two-core or more analysis overhead system insulated power cables, or adding a metal sheath layer, such as plastic/rubber covered wires and cables. The main processes include drawing, twisting, insulation extrusion, cable laying, armoring, sheath extrusion, etc. Different processes are combined differently for different products. This product is mainly used for the transmission, distribution, transmission, substation, and power supply lines for transmitting strong electric energy. The current and voltage passed are high.
3. Wires and cables for electrical equipment
The main characteristics of this type of enterprise product design and development are: a wide variety of specifications, wide application research, more problems when the voltage is 1kv and below, and the need for continuous improvement of new product derivatives for special educational occasions, such as fire-resistant cables, flame-retardant cables, low-smoke halogen-free low-smoke halogen cables, termite-proof, rat-proof cables, oil/cold/heat/wear-resistant cables, medical/agricultural/mining cables, thin-walled wires, etc.
4. Communication cables and optical fibers
In the past 20 years, with the rapid economic development of the network communication technology industry, this product has also shown amazing development speed. From the past, simple telephone and telegraph cables have developed into thousands of pairs of telephone cables, coaxial cables, optical cables, data cables, and even combined communication cables. The structural design size of this type of cultural product is usually smaller and more uniform, and the manufacturing precision requirements are relatively high.
5. Magnet wire (winding wire)
Mainly used in various motors, instruments, etc.
How to identify the quality of wires
First, check for quality system certification; check if the certificate is standard; check for factory name, address, inspection stamp, and production date; check for trademarks, specifications, and voltage, etc., printed on the wire. Also check the copper core cross-section of the wire. High-quality copper has a bright and soft luster; otherwise, it is a substandard product.
Second, try taking a wire end and bending it repeatedly with your hand. Wires that feel soft, fatigue-resistant, strong, and have high elasticity in the plastic or rubber composite material, and no cracks on the wire insulator are superior products.
This is a considerable number of users. Some enterprises even have more common misunderstandings when using wires and cables. Some enterprise users may ignore safety in order to save money, especially when choosing inferior wires and cables with low prices, poor quality, and high accident risks. We know that due to safety factors of wires and cables, the price of wires and cables cannot meet the requirements of some users. Some private enterprises cannot meet the national standards in terms of material selection, production technology, and testing methods, and their safety cannot be guaranteed. In addition, with short meters, their low prices flood the market, catering to some users.
