The Classification and Usage of Cable

A cable is generally twisted by a few or several groups of wires (each containing a minimum of two) like a rope, and there's mutual insulation between every group of conductors and frequently twisted about a central 1, the entire outside is highly covered with insulating layer. The cable has the characteristics of internal energy and external insulation.

Normally it may be classified as follows: energy cable such as Armoured Power Cable, Overhead Power Cable and PVC Insulated Power Cable, control cable, compensating cable, shielded cable, higher temperature cable, pc cable, signal cable, coaxial cable, fireproof cable, marine cable, mine cable, aluminum alloy cable, Underground Cable, Aerial Cable and so on. They are composed of single or multi stranded wires and insulation layers, utilized to connect circuits, electrical appliances, etc.

Now let’s have a appear at the kinds and application of various cables:

1. Flame retardant rubber-sheathed cable: This item is really a series of rubber soft cable products for mining. It’s suitable for coal mining machine and similar equipment device as the energy supply connection. And it is mainly utilized in coal mines.

two. Nuclear grade cable: This item is utilized for nuclear energy station, and applied to the control and signal connection cable in the network of nuclear power station manage system.

three. the goods of bare wire and bare conductor: The main feature of this sort of item is pure metal conductor, with out insulation and sheathing layers, like steel-cored aluminum strand, copper and aluminum bus bar, electric locomotive line, and so on.; and its processing technologies is mainly pressure processing, such as melting, rolling, drawing, stranding / compacted twisted and so on; they are mainly utilized in suburban, rural, user main line, switch cabinet.

four. Power cable: it is primarily used within the communication cable and optical fiber of high voltage energy transmission around the line of electricity generation, distribution, transmission, transform, power provide. With the fast development from the communication business, the product features a tremendous speed of improvement. It has developed from the previous easy cable of telephone and telegram to a large number of phone cable, coaxial cable, optical cable, information cable, and even combined communication cable. The structure size of the item is usually little and uniform, and also the manufacturing precision features a greater requirement.

five. Electromagnetic wire or winding wire: it’s a kind of conducting metal wires with insulating layers, used for the coil or winding of winding electrical products. Its role works by using an electric current to create a magnetic field, or cutting magnetic lines to generate induction present, achieving the conversion in between electric power and magnetic energy, so it's also called as an electromagnetic wire. It’s primarily utilized to get a number of electrical machinery, Instruments and Apparatuses and so on.

six. Within the end, let’s see its new item: the derivative / new goods of Wires and cables are primarily due to the requirements such as the occasion of use, different application specifications and also the convenience of an gear and reducing the price of an equipment, etc., and produced by utilizing the new supplies, special materials, or altering item structure, or improving the process specifications, or combing different varieties of goods group.( Cable Manufacturer)
