What are the specifications of standard cables?

The model number of the common cable is VV or VLV PVC insulated PVC. The common specification is 3 times 10 plus 1 times 1.

Multiply by 16 plus 1 by multiply.

Multiply by 25 plus 1 times 165 times 35 plus 1 times 25 and so on. The role of the cable is to transmit and distribute electric energy, and it is frequently used in underground networks, power stations, power supply for industrial and mining enterprises, and land and water transmission lines.

We often use cables in our daily life, so what are the specifications and models of cables?

1. What are the specifications and models of cables?

The model number of the common cable is VV or VLV PVC insulated PVC.

Common specifications are 3 times 10 plus 1 times 1 times 16 times 1 times 25 times 1 times 165 times 35 times 1 times 25 times 25 times 25 and so on. The role of the cable is to transmit and distribute electric energy, and it is frequently used in underground networks, power stations, power supply for industrial and mining enterprises, and land and water transmission lines.

Specification of cable: 1 square millimeter, specification is 1; square millimeters, the specification is 1; square millimeters, the specification is 1; 4 square millimeters, the specification is 1; 6 square millimeters, the specification is 1; 10 square millimeters, the specification is 7 sticks. There are many varieties and specifications of cables, and there are thousands of specifications.

As the main carrier of power transmission, wires and cables are widely used in electrical equipment, lighting lines, household appliances, etc., and their quality directly affects the quality of the project and the safety of consumers' lives and property. There are many varieties of wires on the market, and it is necessary to use the right wire according to your own electricity load. The appearance of a good wire product should be smooth and round, and the color is uniform, so we should disassemble and check the wire when purchasing to see if the appearance is uniform.

The conductor of the wire should be shiny, and the DC resistance and conductor structure size should meet the requirements of the national standard. The wire and cable products that meet the requirements of the national standard, whether it is an aluminum conductor or a copper conductor, are relatively bright and oil-free, so the DC resistance of the conductor is fully in line with the national standard, with good conductivity and high safety.

List of cable specifications and models:Cable specification and model format: YJV-3 * 185 + 2 * 95, model + several times several This format indicates the number of cable cores in the first few fingers, and the second refers to the cross-sectional area of a single core; It represents a YJV cable consisting of 3 cores with a cross-section of 185 square meters and a 2-core cross-section of 95 square millimeters.

The specifications of power cables are flat, 6 flat, 16 flat, 25 flat, 50 flat, 95 flat, 120 flat; And m.

Key features:Extrude (wrap) the insulating layer outside the conductor, such as overhead insulated cables, or several cores stranded (corresponding to the phase wire, neutral wire and ground wire of the power system), such as overhead insulated cables with more than two cores, or add a sheath layer, such as plastic rubber sheathed wires and cables. The main process technologies are drawing, stranding, insulation extrusion (wrapping), cable formation, armoring, sheath extrusion, etc., and the different process combinations of various products are different.

Cable Specifications and Models:1. Control cable:

These include KVV, KVVR, KVVP, and KVVP2.

Wire and cable is a wire product used to transmit electrical (magnetic) energy, information and realize the conversion of electromagnetic energy. Wires and cables in a broad sense are also referred to as cables, and cables in a narrow sense refer to insulated cables.

Commonly used cable models are: BV - copper core PVC insulated wire; BLV—aluminum-core PVC insulated wire; BVV—copper core PVC insulated PVC sheathed wire; BLVV—aluminum-core PVC insulated PVC sheathed wire; BVR—copper core PVC insulated flexible wire; BVS—copper core PVC insulated stranded flexible wire; BYR—polyethylene insulated flexible wire; BYVR—Polyethylene insulated PVC sheathed flexible wire. rv—copper core PVC insulated installation flexible wire; RVB - copper core PVC insulated flat connecting wire flexible wire; RVV—copper core PVC insulated PVC sheathed flexible wire; ry—polyethylene insulated flexible wire; RYV—Polyethylene insulated PVC sheathed flexible wire.

VV—copper core PVC insulated PVC sheathed power cable; VLV—aluminum-core PVC insulated PVC sheathed power cable; KVV—PVC insulated PVC sheathed control cable; jklyj—XLPE insulated overhead cable; YJV22—copper core XLPE insulated steel tape armored PVC sheathed power cable; YC, YCW - heavy-duty rubber sheathed flexible cable; YZ, YZW - medium-sized rubber sheathed flexible cable; YQ, YQW - light rubber sheathed flexible cable; YH - welding machine cable.

millimeter to millimeter.

Cable specification is the meaning of the representation of the number of cores and cross-sectional dimensions of wires and cables. A normal square cable, which has a diameter of millimeters, is generally used in the arrangement of electric light wires. The square is millimeters, which is generally used for the use of socket seats or small household appliances. Triumph Fortune.

4 square is a millimeter, which is generally used in high-power electrical appliances, such as air conditioners, water heaters, etc. The 6 square is millimeters, and the main circuit is generally used as a home installation.

Cable purchase skills:

Check the length first, the normal wire packaging will be marked, but in order to avoid the business cutting corners, it is necessary to open the inspection beam to ensure that the error is not large.

Check the length of the wire diameter and copper wire diameter.

To check the quality of the copper wire, we need to ensure that the copper wire is copper, and the color can not be yellow, otherwise it means that it is brass and the texture of brass is very hard, we must be careful when purchasing, so as to avoid buying fakes.

Check whether the wire is accompanied by the 3C certification mark, if there is, it means that the wire is produced by a regular business, if not, it is not recommended to buy, because there is no guarantee. <>

The list of cable specifications and models is as follows:1. Specifications and models of VV, VLV, VV22 and VLV22 cables.

2. YJV, YJV22, YJV32, YJV42, YJV43, YJLV, YJLV22, YJLV32 and other cable specifications and models.

3. BV, BLV, BVR, BVVB, BVV cable specifications and models.

Key points for the purchase of cables:

Length: This is one of the tricks often used in cutting corners, some people will say, I bought the wire with a meter mark, look at it is 100 meters, you have to pay attention, he has a meter mark, but in the middle part, some profiteers are less than 10 meters. For example, after 30 meters, 40 meters will be marked.

Silk Diameter: This is one of the most common ways to cut corners in the city. For example, the square BV wire, commonly known as copper single, is a copper wire of one wire.
