The Classification of Wires & Cables
Online, June 24, 2013 (Newswire.com) - Since the invention of cable, it has been widely used in the electric power system, information transmission system, mechanical and instrument system and many other systems. More precisely, cable can be divided into 5 categories. Whirlston, the authoritative wire stripper machine and copper cable granulator manufacturer, will introduce the different cables to you one by one.
1. Bare wires and bare conductor products: the features of the products are: pure conductor metal, no insulation or restrictive coating, such as ACSR, copper and aluminum bus-bar, and electric locomotive lines etc. And the main processing craft is the pressure processing, such as smelting, rolling, and drawing etc. The products are mainly applied in suburban and rural areas, like the user mainline or the switchgear.
2. Power cable: the insulation layer of the cable needs to be squeezed, circled and packaged, and products include crowding insulated cables, the crowding cables over two cores, and plastic/rubber cables, which are mainly used for transmission of high voltage power. The main crafts are drawing, stranding, laying-up, armoring, and sheath extrusion etc, and different products own different combination processes.
3. Cables for electric system: the cables have various specifications that can be used in for different purposes. Usually, the service voltage is below 1KV. Many new products have been invented for different circumstances, such as fire-resistant cable, flame retardant cable, LSZH / LSF cable, anti-termite and anti-mouse cable, and oil resistance/cold resistance/temperature resistance/ wear resistance cable, medical / agricultural / mining cable, thin-walled wires and so on.
4. Communication cable and optical fiber: with the rapid development of communication industry in the recent two decades, its related products come into being with astonishing speed, from the simple telephone and telegraph cable to thousands pairs of words cables, coaxial cables, fiber optic cables, data cables, even the combination of communication cables. Generally, the products are small in size and have uniform structure and it requires high precision manufacturing techniques.
5. Electromagnetic wire: the electromagnetic wire is mainly applied in electrical machines and instruments, which is indispensable to the normal operation of the machines and instruments.
With the development of technology, cable will be applied in many other new areas. At the same time, Whirlston is keeping improving the performance of its wire stripper machines and copper cable granulator, for we strongly believe that technology innovation is a headspring and strong driving force of our development.
