Anonymous users2024-02-12Wires and cables mainly include bare wires, magnet wires, insulated wires for electrical appliances, power cables, communication cables and optical cables. Wires and cables refer to materials used for electricity, communications, and related transmission purposes. There is no strict boundary between "wire" and "cable".
Generally, the products with a small number of cores, small product diameter and simple structure are called wires, those without insulation are called bare wires, and the others are called cables; The larger conductor cross-sectional area (more than 6 square millimeters) is called a large wire, the smaller one (less than or equal to 6 square millimeters) is called a small wire, and the insulated wire is also called a cloth wire.
Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, and so on. They are all made up of stranded wires that are used to connect electrical circuits, electrical appliances, etc.

Anonymous users2024-02-07There are two main types of cables commonly used: copper core cable and aluminum core cable.
Copper core cables are commonly used power cables: YJV YJV22, 35KV and below high and low voltage cables are common.
In the control cable, KVV, KVV22, KVVP, KVVP22 and other shielded control cables, flame retardant control cables, and armored control cables use copper cores.
There are also commonly used small wires: RVV power cord sheath wire, BV, BVR and other wires are also used in copper core cables.
YJLV and YJLV22, which are commonly used in aluminum core cables, are mainly used in power cables.
In addition, there are fireproof cables: BTTZ, YTTW, NG-A, BTLY, low-smoke halogen-free cables: WDZ-BYJ, WDZ-YJY, WDZN-YJY, WDZN-BYJ, etc., these cables are gradually widely used.

2. Nuclear-grade cable: It can work at a temperature of 90 degrees for a long time, and within this standard, its service life can reach about 40 years. There are certain requirements for the laying environment, which cannot be below 0 degrees.
3. Bare wires and bare conductor products: without any insulation and sheath, it is pure conductor metal, which is mainly used in rural areas or suburbs. It's the main line we usually use.
4. Power cable: basically used for power transmission, high current and high voltage.
5. Communication cables and optical fibers: As the name suggests, they are used in the communication industry, which are usually small and uniform, and have extremely high requirements for its manufacturing in terms of precision.
6. Magnet wire (winding wire): used for various motors and instruments.
7. Flexible fireproof cable: it can be said to be excellent in terms of fire resistance, not to mention smokeless and non-toxic when burning, it can also withstand water spray, and has strong resistance to mechanical impact. In addition, there are many advantages, such as corrosion resistance, no electromagnetic interference, long service life and so on.
Bare wire body products.
The main characteristics of this type of products are: pure conductor metal, no insulation and sheath layer, such as steel core aluminum stranded wire, copper-aluminum busbar, electric locomotive line, etc.; The processing technology is mainly pressure processing, such as smelting, calendering, drawing, stranding, pressing and stranding, etc.; The products are mainly used in suburbs, rural areas, user mainlines, switch cabinets, etc. >>>More
i=p (, the power factor is taken, if you really are a pure resistive load you can take 1, then the current is 182A. The current carrying capacity of the conventional 10mm2 copper core cable is 61A when it is laid directly in the ground at 30°, and it is enough to use 4 10 square cables at the same time, considering the protection of electrical appliances (the tripping current of the circuit breaker or fuse is set to 200A). If you select a single cable, you need to select a 3x95+1x50 cable.
The equipment used in the detection is wires, as well as the voltage tester universal meter, which are very useful to him, and the equipment used in the detection is wires, as well as the voltage tester universal meter, which are very useful to him. What are the wire and cable testing equipment, I think there are a lot, for example, first of all, it is a detection program, for example, it is indigo, there must be some professional. Power cable detection of these equipment network set up this equipment should be this professional, even those induction devices, feel this car pen, and so on. >>>More

Pearl River cable is environmentally friendly and of good quality. Nowadays, almost every home has a lot of high-power household appliances, it is recommended to choose a better line, choose a larger one, but you can't buy an inferior one because it is cheap, safety first. Pearl River Cable brand products pursue high quality and high quality, the company has always insisted on the selection of high-quality raw materials at home and abroad, the implementation of strict quality control system, from the source to ensure the quality of the company's products, each wire and cable in line with national standards and international electrotechnical Commission standards. >>>More
