Wire and cable are based on the length of the basic unit of measurement. All wire and cable from the beginning of conductor processing, the conductor's outer layer with insulation, shielding, cable, sheath, etc. made of wire and cable products. The more complex the product structure, the more the level of the overlay.
Jan 04,2018How to distinguish between wires and cables
The difference between a wire and a cable is that the size of the wire is generally small. The larger conductor cross-sectional area (larger than 6 mm2) is called a large wire and a cable, and the smaller (6 mm2 or less) is called a small wire. An insulated wire is Also known as cloth wire. However, cables are sometimes classified as cables in a broad sense.
Jan 03,2018Why use wire and cable shielding
Shielded cable is the use of metal mesh braid layer to wrap the signal transmission line. Braid is generally copper or tinned copper. Shielding is to ensure the transmission performance of the system under electromagnetic interference. The anti-interference here should include two aspects, that is, the ability to resist external electromagnetic interference and the system itself to radiate electromagnetic interference.
Jan 02,2018Wire and cable manufacturing process
Wire and cable manufacturing involves a wide range of processes, from non-ferrous metal smelting and pressure processing, to plastics, rubber, paint and other chemical technology; fiber materials around the package, weaving and other textile technology, metal materials to the package and the metal strip Longitudinal package, welding metal forming process. Equipment involved, such as extrusion machine series, drawing machine series, stranding machine series, around the charter series.
Dec 28,2017The difference between armored cable and ordinary cable
Armoured cables are made of different material conductors in metal sleeves with insulating materials and are processed into a solid, flexible combination. Armored cables include armored thermocouples, armored thermal resistors, armored heaters and armored leads. They are mainly used for temperature measurement, signal transmission and special heating for the chemical, metallurgy, machinery manufacturing, power generation and scientific test. The largest amount is the armored thermocouple.
Dec 27,20170.6/1kv PVC insulated power cable
0.6/1kv PVC insulated power cable is suitable for transmission lines with rated voltage 0.6/1kv, which can be used for transmission and distribution. PVC plastic cheap, good physical and mechanical properties, simple process, but the insulation performance in general. As a result, a large number of low voltage power cables are used to produce low voltage power cables for 1 thousand volts and below, for low voltage distribution systems.
Dec 26,2017Classification of wire and cable
The classification of wire and cable products can help you better understand the specifications and models. The main types of wire and cable are as follows:bare copper wire,power cable,overhead insulated cables,control cable,special cable.
Dec 25,2017What is the difference between power cable and control cable
The Power cable is a cable product that is used to transmit and distribute high power energy in main lines of the power system, including 1-500KV and above all kinds of voltage levels, all kinds of insulated power cables.Control cable insulation wire color is generally black and white printing, low voltage power cable is usually color. Generally, the section of the control cable will not exceed 10 square. The electric power cable is mainly the transmission of the electric power, which is generally large section.
Dec 23,2017XLPE insulated cables
XLPE insulated cable is a suitable distribution network and other areas of the cable, PVC insulated cables with unparalleled advantages. Its simple structure, light weight, good heat resistance, load capacity, not melting, chemical resistance, high mechanical strength.
Dec 21,2017What are the structural components of wire and cable products?
The structural elements of wire and cable products can be divided into four major structural components of wire, insulation, shielding, and sheath as well as filling elements and tensile elements. Wires and insulation are the two basic components that must be available to make a cable product (except for bare wires).
Dec 20,2017How much can 1, 1.5, 2.5, 4, 6 square wires load kW?
When buying electric wires, Many people will ask about a load of wires with the different cross-sectional area. There are 1 square wires, 1.5 square wires, 2.5 square wires, 4 square wires, 6 square wires and so on. The following is to give you a brief introduction of how many watts can be loaded by these wires.
Dec 19,2017What is the difference between PVC and XLPE
The structural elements of wire and cable products can be generally divided into four main structural components of wire, insulation, shielding, and sheathing. For power cables, according to different insulating materials, low-voltage power cables are mainly the following two kinds: PVC insulated power cables and XLPE insulated power cables.

These wires are installed in houses, buildings etc... taken underground to everywhere and anywhere where there is human population and electricity is needed.
Dec 17,2016Wiring safety codes for electrical cable
Wiring safety codes are intended to protect people and property from electrical shock and fire hazards. Regulations may be established by city, county, provincial/state or national legislation, usually by adopting a model code (with or without local amendments) produced by a technical standards-setting organisation, or by a national standard electrical code.

Oct 19,2016Specifications and types of Cable and Wires
Cable is usually composed of several conducted lines or several groups, between which there are the insulation material and be got into a clinch. Meanwhile, over the whole item is the high quality insulation to be the protected cover. The cable is usually adopted in the high or amounted in the earth or water to transmit the telecommunications or electricity. In 1832, Baron Schilling, a Russian army officer, invested the cable that he bore the telecommunication cable in the earth, which put six conducted lines into a glass bar, the first underground cable.
