Electrical wire is one of the very common electrical accessories. We use it and see it every day. It is just because of the electrical wire that many of the remote places can also use electricity to go on the normal life. We cannot imagine that without the electric wire in our life, what we should do. So we can say electrical wire is the necessary electrical accessory in life. Generally, the electric wire has very wide applications. First, the most widely use is the electricity system. The electrical wires used in electricity system are mainly overhead bare wire, the converge-wires, power cable wire and the ordinary wire. Second, information transmission system. The electrical wire used for information transmission system are mainly local cable wireless, TV cable, electronic cable, radio frequency cable, fiber optic cable, data cable, electromagnetic wire and electric power communication or other composite cable wires. Third, Equipment instrumentation electrical wire. This section, except the overhead bare wire, all other products almost all have application, but mainly are the power cable, electromagnetic wire, data cable, instrument and apparatus, cable, etc. Since the electrical wire is a kind accessory that has very important influence to human beings' safety and health, so the electrical wire supplier in the market all must obtain and pass certain qualification then will be allowed to engaged in the manufacturing and supply of electrical wire.
Classifications of Electrical Wires
There are mainly two classifications for electrical wires. The most common one is naked wires and naked conductor products. This kind of product mainly has the features as: it is a kind of pure conductor metal, no insulation and sheath layer, such as the steel calls Al stranding wire, copper aluminum converge-wires and electric locomotive wire, etc.; The processing technology is mainly pressure processing, such as melting, rolling, drawing, stranded inner and tight stranded inner pressure and so on; The products are mainly used in the suburban and rural, user main thread and switchgear etc.
Electric Cable Industry is China
Electric cable industry is China's second big industry only next to automobile industry, product variety meet rate and the domestic market share rate is more than 90%. In the worldwide, China's total output electrical cable value has been more than the United States, and has become one of the world's largest electrical cable manufacturers. Along with the rapid development of China's electrical wire and cable industry, the number of new electrical wire and electrical cable enterprises is rising, the industrial overall technical level is vastly improved. The electrical wire and cable manufacturing industry belongs to a electrical equipment industry, and the technology content is relatively low, the entry threshold is low, the user is mainly the state power grid corporation, the market situation leads to many electrical equipment suppliers lose the pricing ability, the whole industry face the problem of high prices of raw materials after a quick expansion, and the industry growing competition if geting fiercer, and profit tends to decline. In view of the development prospects of our country's electric power industry, electrical wire and cable manufacturing industry as a teen industry under the push of big environment industry still has a good space to develop.
