What kind of wire is a good wire

The strong current part usually refers to the AC380/220V power line, such as sockets, lighting equipment, air conditioning, heaters, kitchen appliances, etc. Decorate a process in the family, the quality of strong electric wire is very important, this need not explain too much.

So, how to judge the stand or fall of strong electricity wire manufacturer?

One, commonly used for home decoration of the strong BV wire is usually used in the process of home decoration.

There are many types of wire, commonly used wire symbol is BVBVR, BVVB, RVV, the difference is as follows:Two, wire manufacturer BV wire how to identify?

1. Length identification Can say, basically all electric wires on the market are insufficient 100 meters, satisfy the electric wires of 98 meters above, had been the manufacturer of conscience.But if you want to solve the plate with a ruler a little bit of length, not only very troublesome, but also let the shop can see you are small white.So, is there a way to calculate the length of the wire without dissolving the disk?

Yes, the current industry recognized a measurement method, the error is basically within 1 meter:

The method is as follows:

A: the number of wires in the horizontal plane

B: the number of wires in the vertical plane

C Length: the length from any outside of the reel to the far inside edge of the inner reel

The calculation formula is as follows: Number of wires in meters = Number of wires A x Number of wires B x length C x 3.14

For example, conductor BV2.5, after initial measurement, the number of A is 12; The number of B: 16; The length of C: 16.5 centimeters, that is, 0.165 meters, the length of the wire can be calculated as: 12×16×0.165×3.14 = 99.47 meters.

This method also works for 4 square and 6 square wires.

2. Line diameter identification

We often say 2.5 square BV line, commonly known as single core wire or copper plastic wire, refers to the copper wire, that is, the cross-sectional area of the COPPER wire BV2.5 line is 2.5 square millimeters. Then, according to the area formula of the circle, the diameter of the copper wire should be about 1.78mm, which is the national standard.

How the quantity? Use vernier calipers:

In addition, it is important to note that when measuring from both ends of the reel, even if the wire diameter is large enough, it does not necessarily mean that the whole wire diameter is sufficient. Because a lot of shoddy products, from the beginning of three meters is no problem, but after three meters began to thin, to Z after three meters or so, and restore to the normal diameter, this is because the manufacturer in the process of production of copper wire drawing processing. So when buying wire, many old hands will ask the boss: “Is the wire pulled in the middle?” If the boss is afraid to say no, at this time, to be on high alert.

3, copper identification

The main cost of the wire is the metal conductor, while the GB plastic copper wire uses oxygen-free copper as the conductor. Non-standard wires will use metals with low copper content as conductors, such as brass, galvanized copper, copper-clad copper (brass covered with a layer of copper), even copper-clad aluminum, copper-clad steel, etc. Wires are much more resistant than copper, generating a lot of heat and causing accidents.

How do you tell?

Generally speaking, the more yellow the color, the less copper content. Brass is pure yellow, and copper is a little reddish. You can use pliers to cut, take a look at the section, see if the color is consistent, at least it is easy to judge whether it is copper wrapped aluminum and so on

4. insulation identification

First look at the thickness of the wire sheath (insulator). The national standard 1.5-6 square wire without oxygen copper requires the sheath thickness (insulation thickness) of 0.7mm. If it is too thick, a corner may be caused by a lack of inner core diameter. ; And then judging the quality of the insulator, the fake product, it’s easy to crack the wire casing by pulling it by hand.

5. Weight identification

Good quality wires are usually within the specified weight range. For example, the weight of the commonly used BV1.5 line is 1.8-1.9kg per 100m;

The weight of BV2.5 line is 3-3.1kg per 100m;

The weight of BV4.0 line is 4.4-4.6kg per 100m.

Poor quality wires are not heavy enough, or not long enough, or the copper core of the wire is too foreign.
