What is the diameter of a 400 square millimeter cable

400 mm².

The diameter of the cable is millimeters.

Calculation method: s = r = is the cross-sectional area, d is the diameter) d = (s mm).

The formula for calculating the diameter is as follows: diameter d= (4s).

Several groups of high-voltage cables approximate the outer diameter.

yjlv-6/10kv-3*400

yjlv-12/20kv-3*400

yjlv-21/35kv-3*400

yjlv-26/35kv-3*400

This is all national standard data, if you are purchasing a discount line, it should be a little smaller than this.

The diameter of the cable is 400 square millimeters.

Knowing the square of the wire, calculate the radius of the wire using the formula for finding the area of a circle: Number of wires squared (square millimeters) = Pi (square of the radius of the wire (millimeters).

The square number is known to be 400, and then the square is multiplied by two to get the diameter.

If you don't know, don't mislead everyone, you have no culture again, although you don't know how thick the cable is, but you also know how to calculate the diameter! 400 is the square number, divided by , and then multiplied by two is the diameter, but considering that the cable is not a solid core, the actual diameter is larger, and it should be multiplied by a coefficient!

Of course, 400, 400 divided by the root number, the cable is recorded in area, in square millimeters.

The diameter of the cable refers to the cross-sectional area of each conductor, knowing the square of the wire, the radius of the wire is calculated using the formula of finding the area of the circle: Number of wires squared (square millimeters) = pi (square of the radius of the wire (millimeters).

The known square number is 400 =

It depends on the structure. 400 square only indicates the cross-section of the conductor, and it is not clear what the package on the outside looks like, so how can we know the diameter.

Summary. Hello, dear, I am happy to answer for you, how many kilowatts can be used for 400 square copper core cables" The cable current of such a large cross-sectional area can not be calculated according to 5-8 amperes per square, but can only be calculated, so in 600-800 amps, 800 to 1000kw. "Hope it helps.

How many kws are available for 500mm2 and 630mm2 copper amplifiers

This also starts with the current carrying capacity of 500mm2 copper wire. Knowing the current, it is possible to estimate the power carried under different conditions of use. For the average user, there are no shortcuts to how much current the cable can pass through.

Because the current carrying capacity increases with the increase of the cross-sectional area, it is not proportional, so the data can only be obtained by checking the current carrying capacity meter.

By checking the meter, it is known that 500 square meters can pass through the current of 855A (the current will be different in different laying methods). If calculated according to three-phase 380V, 855AX 3X380V = 562 kW. In addition to the current carrying capacity of the wiring, the voltage drop should also be taken into account.

If the pressure drop is calculated by 10%, then the maximum transmission distance is:

Because the nature of the load is not stated, and the transmission method and voltage are not stated, it can only be calculated so far. Generally speaking, considering the voltage drop caused by the large starting current, the surplus should be larger.

s = cross-sectional area, d diameter) d = (4s ) d = (4 120 mm).

The manufacturing of wires and cables is completely different from the way most electromechanical products are produced. Mechanical and electrical products are usually assembled into parts from another part, and multiple parts are then assembled into a single product, and the product is measured in units or pieces. Wires and cables are measured in terms of length.

All wires and cables are made from conductor processing, and insulation, shielding, cable-forming, and sheath are added layer by layer to the periphery of the conductor to make wire and cable products. The more complex the product structure, the more layers there are.

I hope mine is helpful to you.

The diameter of the 400 square millimeter cable imitation is millimeters. Knowing the square of the wire, calculate the radius of the wire using the formula for finding the area of the circle: Number of wires squared (square millimeters) = pi (square of the radius of the wire (millimeters).

It is known that the square number is 400, and then the square is multiplied by two to get the diameter.

There is no data alone.

The purchase of cables is very important, and it needs to be determined according to the use of the cable to ensure the normal use of the later stage and avoid the necessary trouble. So what is the diameter of a 50 square cable.

The diameter of the 50 square cable is about square millimeters, and the national standard cable is composed of 19 thin copper wires, and the diameter of a single thin copper wire is, so the core diameter of the combined cable is, and then the outer insulation of the cable is skinned, because when calculating the diameter of the cable, the thickness of the insulation skin needs to be calculated twice, so the national standard size of the 50mm square cable is. So 250 square cable diameter is multiplied by 5 equals 57mm

mm diameter = square root of area x2 = mm.

Square of the cable = Pi (4 squared of the wire diameter.

35 square means that the size of the wire is 35 square millimeters, which is its cross-sectional area.

The formula is: cross-sectional area (s) = square of radius (r) pi ( ).

Hello, I have seen your question and am sorting out the answer, please wait a while

<> do you have any questions?

The diameter of the cable is 400 square millimeters.

The diameter of the cable is 400 square millimeters.

Probably due to system reasons.

You didn't see my reply above.

Sorry for the inconvenience.

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.
