Definition of wire and cable: Wire and cable is used to transmit electrical energy, transmit signals and achieve electromagnetic energy conversion electrical products.

Classification of wire and cable: according to the manufacturing process, structural characteristics, functional requirements, product use can be divided into five categories:

1, bare wire and bare conductor - refers to only conductor, without insulation layer of products, including copper, aluminum and other metal and composite metal round single wire, various structures of overhead power lines with twisted wire, flexible wiring, wire and shape material. The main points of the product process are pressure processing, such as melting, calendering, drawing, stranding/compression stranding, etc. Main use: suburbs, rural areas.

2, power cable - Power cable is used in the backbone of the power system for the transmission and distribution of high-power electricity wire products. Including 1-500kV and above a variety of voltage levels, a variety of insulation power cables. The main technological processes of this kind of cable are drawing, stranding, insulation extrusion, cable forming, armor, sheath extrusion, etc. Various product models are different, and the process combination has certain differences. Main use: power transmission, distribution, transmission, transformer, power supply line in the transmission of strong electric energy.

3, electrical equipment with wire and cable - from the power system distribution point to transmit power directly to a variety of electrical equipment, appliances of a variety of power connection lines, a variety of industrial and agricultural electrical installation lines and control signals with wire and cable. Such products are widely used, and there are many varieties, and the structure and performance of the cable should be determined in combination with the characteristics of the equipment used and the use of environmental conditions (the use voltage is mostly 1KV and below). Therefore, in addition to those large number of general purpose products, there are many special special cables.

4, Communication cables and optical cables - Communication cables are cables that transmit telephone, telegraph, television, radio, fax, data and other telecommunications information. The structure size of this kind of product is usually small and uniform, and the manufacturing precision is very high.

5. Electromagnetic wire - insulated wire used to manufacture coils or windings in electrical products. Also known as winding wire. Mainly used for all kinds of motors, instruments and meters.

Type of wire and cable:

Each kind of wire and cable has its name, and the cable model is generally represented by a series of Chinese pinyin letters and Arabic numerals. A complete model consists of the following seven parts, that is, the various components that make up the cable:

1- Classification or purpose number, indicated by the first letter of pinyin. For example, JK stands for overhead line; C stands for Marine cable; K stands for control cable and so on.

2- Conductor core code. Such as T copper; L aluminum; G steel; H alloy, etc.

3- Insulation layer code. Such as V PVC insulation, Y polyethylene insulation, XLPE crosslinked polyethylene insulation, X rubber insulation, E ethylene propylene rubber insulation and so on.

4- Shield code. Such as V polyvinyl chloride sheath, Y polyethylene sheath and so on.

5- Shape feature code. Such as B flat, Q light, R soft.

6- Outer sheath code. If expressed in numbers, its meaning is shown in the following table, the armor layer outer sheath code.

7- A code used to indicate the particularity of the product, such as BV-90 means that the heat resistance level is 90℃.

Qingdao Tianxing Cable Co., Ltd. focuses on the production of customized wire and cable manufacturers, main: fire wire and cable, power cable, control cable and other products, exported to more than 40 countries and regions around the world, the annual production capacity of 1 billion yuan. 6000 square meters of storage, standing hundreds of millions of inventory, order demand for rapid distribution and delivery, large prices more favorable.
