Dear, hello, it is a pleasure to serve you, the answer is as follows: four square wires ** in yuan one meter. Under normal circumstances, 4 square copper wire will not be particularly expensive, and each meter should be between yuan and 2 yuan. When most manufacturers produce four-squared copper wires, the length of each roll should be about 100 meters, so when we buy these copper wires, we can choose how many rolls to buy according to actual needs.

A milliliter is a unit of volume, a gram is a unit of weight (mass), there is no equal relationship between them, a milliliter is a cubic centimeter, and the mass of a unit volume of an object is the density, such as the density of water is 1 gram milliliter, the density of oil is gram milliliters, and the density of iron is gram cubic centimeters. So 4 milliliters of square cable wire is equal to the size of 4 grams per meter.

Four square cable lines cost 3-16 yuan a meter.

The 4 square single core is about 3 yuan 1 meter, the 4 square 2 core is about 8 yuan 1 meter, and the 4 square 3 core is about 16 yuan 1 meter. The appearance of the cable meets the requirements of the standard: smooth and round, uniform color.

And the appearance of counterfeit inferior cables is rough and dull. For rubber insulated flexible cables, it is required to have a round appearance, and the sheath, insulation, and conductor are tight and not easy to peel off. The fake and inferior products have a rough appearance, large ovality, and low sheath insulation strength, which can be torn off by hand.

The role of the cable:

The function of the cable is to transmit electricity, and can be used to transmit signals, or realize electromagnetic energy conversion, which is an electrical product. There are many types and specifications of it, first of all, when transmitting electricity, you can choose a kind of matching cable or power cable. If it is used to transmit signal information, you can choose a TV electric limb ruler cable or optical fiber cable, as well as a local telephone cable.

If it is used for mechanical equipment or some instrumentation, the range of selected cables includes much higher than macro, except for overhead bare wires, others can be used. Therefore, from a popular point of view, cables are inseparable from cables in daily life, including construction projects, agricultural scientific research, space and marine fields. It has a very wide range of applications and is very valuable.

What is the diameter of the <><4x25 cable.

The diameter of the 4x25 cable is the maximum rated temperature of the cable conductor is 70C, and in the event of a short circuit, the maximum temperature of the cable conductor does not exceed 160C, and the maximum duration does not exceed 5s. In addition, the ambient temperature when laying 4x25 cables needs to be higher than 0 degrees, resulting in a minimum bend radius of more than 10 times the outer diameter of the cable.

How to choose 4x25 cables.

1. Look at the packaging, the national standard line is generally better, cleaner, and has a texture in your hand.

2. Open the package to see the cable inside, to the 6 square meters of the national standard cable stipulates that the skin is thin (the thickness of the insulation layer), if it is too thick, it is non-standard, and there is no doubt that the core is insufficient. The thread hair can be pulled hard, and the ones that are not easy to push are generally national standards.

3. Bake with fire, turn off the fire within 5 seconds after it comes out, and have a certain fire resistance for the national standard line.

4. Look at the inner core, the higher the brightness of the inner core material, the better the copper, the brightness is uniform, bright and textureless. The national standard stipulates that the inner core must be made of oxygen-free copper. Non-standard, such as black rod copper, is likely to have potential accidents.

5. The size of the inner core has certain regulations in China, but it is not very strict. But there are many, just a little, often invisible deviations to the naked eye.

6. There is no mandatory requirement for the length of rice in China, but many manufacturers have also stirred rice. Beating rice is not necessarily the national standard, but the general national standard generally does not make a splash of rice. Non-standard punched rice is just one way.

Summary. Hello dear <>

Glad for your question. The radius of the copper wire = 4 2 = 2mm, and the area of the copper wire = the square of the radius * the square. So, a copper wire with a diameter of 4mm is squared.

What is the size of a 4 cm diameter cable?

Hello dear <>

I'm glad to answer your questions. The radius of the copper wire = 4 2 = 2mm, the area of the copper wire = the square of the radius of the ascending hall * the square. Therefore, the diameter of 4mm copper wire is the square of the trace.

Hello, the diameter of the main cable is 4 cm, is it more than 185?

Hello dear <>

Glad for your question. The diameter of the cable of 185 square is a single core).

4 main cables.

Aluminum wire material. Hello dear <>

I don't quite understand what you mean, can you elaborate on that?

It is the aluminum wire in the four centers of the main cable, the diameter is four centimeters, how to read his specifications.

Four-core aluminum cable models are: aluminum core cable model VLV-3 * 10 + 1 * 6 aluminum core ruler family feng cable, spike round VLV-3 * 25 + 1 + 16 aluminum core cable, VLV-3 * 35 + 1 * 16 aluminum core cable, LV-3 * 70 + 1 * 35 aluminum core cable, VLV-3 * 95 + 1 * 50 aluminum core cable, VLV-3 * 120 + 1 * 70 aluminum core cable, VLV3 * 150 + 1 * 70 aluminum core cable, VLV3 * 185+1*95 aluminum core cable, VLV3*240+1*120

4 square (mm) cable diameter is mm.

The calculation is as follows:

s=denotes cross-sectional area, denotes pi, denotes diameter);

d= (4s)4-4 mm). Zhi Lu Chun.

Solution: 4 square millimeter cable is the size of the cross-sectional area of the core slag mass line, and its diameter can be obtained according to the cross-sectional area of the cable s= r Yu Sen can obtain r= (s), and the diameter of 4mm cable, r= (s) 4, its diameter d=2r=2

A: The diameter of the cable is 4 square millimeters. Such as ruining oranges.

How much copper does a 4-core*4 square national standard cable contain per meter?

The national standard wires are produced in accordance with the national standard, and its calculation method is very simple: the mass of copper = 4 x the cross-sectional area of the copper core x the density of the copper. According to the formula, 4 square national standard cables contain about 150g of copper per meter.

Square aluminum core armored cable parameters:

Round pressed conductor outer diameter:

Insulation thickness:

Outer diameter after insulation:

Thickness of the thinnest point of the outer sheath:
