5, what is the cable adapter? A: The device that connects the cable with the conductor, insulating shielding layer and protective layer of the cable to connect the cable line is called the cable connector.

Wire and cable application

1. Power system

The main wire and cable products used in the power system are bare overhead wires, bus bars (busbars), power cables (plastic cables, oil-paper force cables (basically replaced by plastic power cables), rubber sheath cables, overhead insulated cables), branch cables (replacing some bus bars), electromagnetic cables, and electrical equipment wires and cables for power equipment.

2. Information transmission system

Wires and cables used for information transmission systems mainly include local telephone cables, television cables, electronic cables, radio frequency cables, optical fiber cables, data cables, electromagnetic cables, power communication or other composite cables.

3, mechanical equipment, instrumentation system

This part in addition to the overhead bare wire almost all other products are used, but mainly power cables, electromagnetic cables, data cables, instrumentation cables and so on.

Wire and cable products are mainly divided into five categories

1, bare wire and bare conductor products

The main features of this product are: pure conductor metal, no insulation and jacket layer, such as steel core aluminum stranded wire, copper and aluminum bus, electric locomotive line; The processing technology is mainly pressure processing, such as melting, calendering, drawing, stranding/compression stranding, etc.; Products are mainly used in the suburbs, rural areas, user main line, switchgear and so on.

2. Power cable

The main features of this product are: wire and cable extruded (wound) insulation layer outside the conductor, such as overhead insulated cable, or a few cores stranded (corresponding to the phase line, neutral line and ground line of the power system), such as more than two core overhead insulated cable, or add a sheath layer, such as plastic/rubber sheath wire and cable. The main process technologies are drawing, stranding, insulation extrusion (wrapping), cable forming, armor, sheath extrusion, etc. There are certain differences in different process combinations of various products.

Products are mainly used in power transmission, distribution, transmission, transformer, power supply lines in the strong electric energy transmission, through the current (tens of amps to thousands of amps), high voltage (220V to 500kV and above).

3, electrical equipment with wire and cable

The main characteristics of this kind of products are: a wide variety of specifications, a wide range of applications, the use of voltage in 1kV and below more, in the face of special occasions constantly derived new products, such as refractory cables, flame retardant cables, low smoke halogen free/low smoke halogen cables, termite-proof, anti-mouse cables, oil/cold/temperature/wear resistant cables, medical/agricultural/mining cables, thin wall wires.

4, communication cable and optical fiber (brief introduction)

With the rapid development of the communication industry in the past 20 years, products have also developed at an amazing speed. From the past simple telephone and telegraph cables have developed to thousands of pairs of cable, coaxial cable, optical cable, data cable, and even combined communication cables.

The structure size of this kind of product is usually small and uniform, and the manufacturing accuracy is high.

5, electromagnetic wire (winding wire

Mainly used for all kinds of motors, instruments and meters.

Derivative/new products of wire and cable

Wire and cable derivatives/new products are mainly due to the application of different application requirements and the convenience of equipment and reduce the cost of equipment requirements, and the use of new materials, special materials, or change the product structure, or improve the process requirements, or the combination of different varieties of products.

Different materials are used, such as flame retardant cables, low smoke halogen free/low smoke and low halogen cables, termite-proof, rat-proof cables, oil/cold/temperature resistant cables, etc.

Change the product structure such as: fire-resistant cable;

Improve process requirements such as: medical cables;

Combined products such as: OPGW, etc.;

Easy to install and reduce equipment costs such as: wire and cable prefabrication branch cable.

Qingdao Tianxing Cable Co., Ltd. focus on supporting wire and cable production customization manufacturers, main: exports 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.
