As is known to all, wire and cable industry is known as the "blood vessels" and "nerve" of the national economy, since our founding, especially since the reform and opening, our country economy fast development, the electric power construction demand, build on the Chinese economy high speed development of the wire and cable industry has been rapid development of the train. Here is a list of the market information about the cable industry.

I. industry definition and classification

What is a cable?

Definition 1: a conductor that is insulated from one or more layers of insulation and the outer layer of insulation, which is used to transmit electricity or information from one place to another.

Definition 2: usually consists of several or several groups of wires (at least) two in each group of twisted rope like cable, insulated between each group of wire, twist and often revolve around a center, the bread has a highly insulating layer. The cable has the characteristics of internal electricity and outer insulation.

The classification of the cable are divided into: power cable, control cable, compensation cable, shielded cable, high temperature cable, computer cable, signal cable, coaxial cable, fire-resistant cable, Marine cable, mine cable, aluminum alloy cable and so on. They are made of single or multi-strand wires and insulation, which are used to connect circuits, electrical appliances, etc.

The cables are also available in a variety of models, including the type and sequence of the cables.

[1: category, use] [] 2: conductor insulation] [3: [4: inner sheath] [5: structural characteristics] [6: outer covering or derived] - [7: use features]

The first letter in the English name of the macromolecular material means that each item can be one or two letters. The sixth term is one minus three Numbers.

The conclusion of cable development in 2014

The size of nearly thousands of wire and cable enterprises in our country, 97% of whom are small and medium-sized enterprises, equipment utilization rate from 30% to 40% on average, far below the equipment utilization rate of more than 70% of the international level; More than 90 per cent of capacity is concentrated on low-end products, with an average of less than 1 per cent of sales. High-end products, such as aerospace, nuclear power, electronics, car cables and high-voltage cables, are mainly imported.

It is not hard to see, the data clearly reflect the wire and cable industry development present situation, although has been acknowledged as the second largest industry in China, but excess capacity, many small and medium-sized enterprises, industry concentration degree is extremely low, mid-range products less competitive, technology r&d, hindered the healthy development of the industry. In particular, the quality factors are directly related to the "lifeblood" of the enterprise.

To this, the consensus is that insiders to speed up the transformation and upgrading, to speed up the merger and reorganization, prevent overcapacity, always adhere to quality first, only in this way, to ensure that industry healthy and orderly development, and reasonably.
