How many meters is a new bundle of wires

Domestic householdBV lineMost are 100 meters long.

According to the type, use and customer requirements, the common lengths of wires are 50 meters, 90 meters, 100 meters, 200 meters, 305 meters (1000 feet), 610 meters (2000 feet), 1000 meters, etc.

Wire and cable products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Wire and cable in a broad sense is also referred to as a cable, and a cable in a narrow sense refers to an insulated cable, which can be defined as: a collection composed of the following parts; One or more insulated cores, as well as their respective cladding, total and outer sheaths, and cables may also have additional uninsulated conductors.

Applications:

1. Power system.

The wire and cable products used in the power system mainly include overhead bare wires and busbars.

Bus), power cables (plastic cables, oil-paper power cables (basically replaced by plastic power cables), rubber sheathed cables, overhead insulated cables), branch cables (replacing part of the busbar), magnet wires, and electrical equipment wires and cables for power equipment, etc.

2. Information transmission system.

The wires and cables used in the information transmission system mainly include local telephone cables, television cables, electronic cables, radio frequency cables, optical fiber cables, data cables, electromagnetic wires, power communications or other composite cables.

3. Mechanical instrument system.

In addition to overhead bare wires, almost all other products in this part have applications, but mainly power cables, magnet wires, data cables, instrumentation cables, etc.

According to the type, use and customer requirements, the common lengths of wires are 50 meters, 90 meters, 100 meters, 200 meters, 305 meters (1000 feet).610 m (2000 ft), 1000 m, etc.

Most of the domestic household BV lines are 100 meters

A roll of wire is 100 meters. Mould leather liftThe national standard wire is generally nominal 100m in a roll, and the tolerance range is plus or minus, that is to say, a roll of 100m long allowable error is plus or minus. The most common home improvement wire is 100 meters per roll, and the most common network cable is 305 meters per roll, and there are also 100 meters.

Introduction to wires

A wire is a wire that transmits electrical energy. It is divided into bare wire, magnet wire and insulated wire. Bare wires have no insulation layer, including copper, aluminum flat wires, overhead stranded wires, and various profiles such as profile wires, busbars, copper bars, aluminum bars, etc. It is mainly used for outdoor overhead and indoor busbars and switch boxes.

Magnet wire is an insulated wire that generates a magnetic field when energized or induces an electric current in a magnetic field.

It is mainly used for electric Danbi machine and transformer coil and other related electromagnetic equipment. Its conductor is mainly copper wire, which should have a thin insulation layer and good electrical and mechanical properties.

and heat-resistant, moisture-proof, solvent-resistant and other properties. Choose different insulation materials.

Different characteristics are available. Magnet wires mainly have enameled wires.

and wrapping wire.

Enameled wire is made by coating insulating paint on bare copper wire, with a thin insulation layer and a small footprint, which is widely used in various electrical appliances and instrumentation. The holding properties of enameled wires vary depending on the nature of the insulating material used. The main winding wires are yarn-wrapped wire, silk-wrapped wire, glass wire-wrapped wire, paper-wrapped wire and plastic film wire-wrapped, among which yarn-wrapped wire and silk-wrapped wire may be eliminated due to poor temperature resistance and large occupied volume.

The conventional is a roll of 100m, but many lines will not reach 100% when they leave the factory, and will be less.

Whether it is a sheath line or a BV line, it is generally 100m or 95m

A roll of wire has meters in between. The national standard wire is generally nominal 100m in a roll, and the tolerance range is plus or minus, that is to say, a roll of 100m long allowable error is plus or minus. Home improvement wires are most commonly 100 meters per roll, there are also 50 meters and 200 meters.

Network cables are most commonly 305 meters per roll, but there are also 100 meters. It is generally 100m, and ** quotient also says that it is 100m. However, we have measured many times on the construction site, and many of them cannot reach it, that is, about 97m, and even less than 95m.

A roll of wireTherefore, you should compare many ways when buying wires, choosing manufacturers, sellers, etc., the current line nominal is 100 meters, but there is not enough number, and the one that can reach 95 is 100. There are also previous rolls that are 50 meters.

1. The national Jane Shen standard wire is generally nominal 100m in a roll, and the tolerance range is plus or minus, that is to say, a roll of 100 meters long allowable error is positive or negative;

2. However, the vast majority of manufacturers cannot meet this standard, unless it is a large user purchasing in large quantities;

3. Commercially available cables and wires can reach 90 meters, even if they are a loss of conscience, some are only 70 meters. Appearance standards, the wire must have a certification mark, manufacturer, wire diameter, etc., and the ground wire refers to the yellow-green insulation layer; mechanical strength;

4. The insulation (generally greater than 100m) and compressive strength (500V to 1500V) of the sheath;

5. Wire resistance (no more than a certain resistance under a certain wire diameter, conductivity, and length) shall not crack at a high temperature impact of 150 degrees, and the wire shall not crack at a low temperature of -30 degrees.

A roll of wire is 35 yuan a meter, but sometimes it is not necessarily, some are expensive and some are cheap, and it is almost the same **. Depending on what brand you have, a volume of Tongling Yangtze River is about 200 volumes. It is divided into bare wire, magnet wire and insulated wire.

Bare wires have no insulation layer, including copper, aluminum flat wires, overhead stranded wires, and various profiles such as profile wires, busbars, copper bars, aluminum bars, etc.

Fabricate. Starting with copper slag, it doesn't have to be pure copper, anything, as long as it contains copper. Because the components that are not copper will melt in the copper water and burn them clean. To reach the boiling temperature of copper water, factory workers pump extremely high-pressure oxygen into the boiler.

The molten copper water (which contains some impurities) flows into the mold. The mould is then immersed in water and cooled to a machinable temperature. After cooling, the mold is sent to a giant electrolysis bath to remove impurities.

The finished product is these much cleaner copper plates. To be made into wires, the copper plates are sent to a new workshop where they are melted again. The melted pure copper water is cooled and drawn into thicker copper strips.

Thicker copper strips are stretched to become wires of the required thickness.

2x3x10 = 60 (decimeters).

A: The length of this wire is 60 decimeters.

100 meters. Normally, it is 100 meters, and some manufacturers are 95 meters. However, for national standard products, there are no specific regulations in this regard, and its main requirement is that the quality must be up to standard.

The precautions for power connection are as follows:

Use pliers to connect wires, most electricians will use pliers to connect the terminals, first of all, we should be wound in accordance with the correct winding method, and then the extra wires are folded back as a ring buckle, and finally cut off the excess wires, if you use pliers to connect the terminals, the effect of the connection is generally better, and it should be no problem to use it for more than ten years.

The use of electric drill terminals, the use of electroosmosis drill can quickly twist the copper wires together, the method of this terminal is faster than the use of pliers to the terminal, however, the use of electric shock drill terminal has certain requirements for the electrician's process, if the speed of the electric drill is not well controlled, it will be easy to connect the wire, or the effect of the wiring is not good, it will bring certain potential safety hazards of electricity. <>
