2 How many kilowatts of power can a 5 square millimeter aluminum wire carry?

The maximum carrying power of the square wire (national standard) is kilowatts.

In general, the safe carrying capacity of a square millimeter copper wire is 9 amps and 2 kilowatts in the case of a standard household electricity voltage of 220 volts.

The safe carrying capacity of a square millimeter copper core wire is 15 amps, which is about kilowatts at 220 volts.

The safe carrying capacity of 4 square millimeters of copper core wire is 24 amps, and in the case of 220 volts, about kilowatts.

Under normal circumstances, the square aluminum wire can carry a load of no more than 2 kilowatts.

The following is a formula for estimating the current carrying capacity of the wire:

To illustrate, this formula is based on the condition that the aluminum core insulated wire is laid at an ambient temperature of 25).

5 in ten, 2 in 100;

Two. Five, three-five boundaries;

Seventy, nine. five, two and a half times;

Pipe-wearing, temperature, eight, nine, folding;

Copper wire upgrade calculation;

Bare wires are doubled.

Explanation of the formula: 5 out of ten"It means that the cross-section is below 10, and the interception current is five times the number of cross-sections, such as the allowable current of the line is estimated to be 5A*; “

"100 on 2" means that the cross-section is more than 100, and the current carrying capacity is twice the number of cross-sections, such as the allowable current of 150 lines is estimated to be 2A*150 300A;

Two. "Five, three or five boundary" refers to the cross-section 25 and 35 is the boundary between four times and three times, 25 belongs to the range of four times, but close to the side of the triple change, it is four times according to the formula, that is, 4a * 25 100a, but the actual is less than four times (97a according to the manual), and 35 is the opposite, according to the formula is three times, that is, 3a * 35 105a, in fact it is 117 aHowever, this does not have much impact on use.

Of course, if you can "have a number in your chest", when choosing the wire cross-section, 25 does not let it be full to 100A, and 35 can slightly exceed 105A;

Seventy, nine. five, two and a half times; "It means that the current carrying capacity of the cross-section between 70 and 95 is a multiple of the number of cross-sections, such as.

"Pipe penetration, temperature, eight, nine, fold" means that if it is laid through the pipe (including the laying of groove plates, etc., that is, the wire is covered with a protective sleeve, which is not exposed), after calculating the current according to the above, it will be discounted by eight (multiplied by if the ambient temperature exceeds 25, it should be calculated and then discounted by nine folds (multiplied).

Copper wire upgrade calculation; The bare wire is doubled", "copper wire upgrade calculation", that is, the cross-section of the copper wire is upgraded by one level according to the cross-sectional order, and then calculated according to the corresponding aluminum wire conditions.

Regarding ambient temperature: according to the regulations, it refers to the average maximum temperature of the hottest month of summer. In fact, the temperature is fluctuating, and in general, it does not affect the conductor loading very much. Therefore, discounts are only considered when there are more than 25 in certain high-temperature workshops or hotter areas.

There is also a situation where both conditions are changed (the temperature is higher when the pipe is threaded), then the current is calculated according to the above and then discounted by 8%, and then discounted by 9%. Or simply make a seven-fold calculation at a time (i.e., about this can also be produced is "through the tube, temperature, eight, nine fold" meaning.

Check the "Electrician's Manual" square aluminum core wire at a temperature of 40 degrees The interception rate is 20A:

220V single-phase electricity can be carried with 220V 20A=4400W.

Look at the way it is laid. Bright-wire single-phase 220V2500W. Dark wire through the pipe 2000w. The conductor allows the load to be dependent on the heat dissipation conditions.

The square aluminum core wire, if it is a household appliance, can withstand a maximum power of 4000 watts.

Square copper wire can drive 3500 watts to 5000 watts.

Because copper wire can carry a current of 16A to 25A, the converted power is 3500 watts to 5500 watts.

The rated current of the wire will not change, and the power is the product of voltage and current, which means that the difference in operating voltage will lead to a change in the power of the wire load. For example, the rated current of the square copper wire is 15 amps, and 220 volts is 3300 watts, if it is 110 volts, it can only load 1650 watts, and if the voltage is lower, the load power is smaller.

Precautions

Cable current-carrying port: estimation formula: multiply by nine at 2.5 and subtract one by one straight number up. Thirty-five times three .five, double and double groups minus five conditions have a change plus conversion, high temperature nine-fold copper upgrade, the number of pipe roots is two, three, four, eight, seven and six fold full load current.

The mantra does not directly indicate the current carrying capacity of various insulated wires (rubber and plastic insulated wires), but is expressed by "multiplying the cross-section by a certain multiple", which is obtained by mental arithmetic. The multiplier decreases as the cross-section increases.

Hello, 2 kW, because the load capacity of the aluminum wire depends on the current, voltage and wire diameter. In general, the square grinding millimeter aluminum wire is suitable for the current below 10 amperes, and the maximum load power is the aluminum wire voltage of the square millimeter multiplied by the current, usually about 2 kilowatts. However, this is only a rough estimate, and the specific load energy rubber force needs to be calculated and confirmed according to the specific conditions of the line and the environment in which it can be used.

If you need more accurate estimates and calculations, it is recommended to consult a professional electrical engineer or technician for an evaluation. In addition, in the process of selecting and using aluminum wire, it is also necessary to pay attention to choosing the appropriate aluminum wire specifications, installing and maintaining the line correctly, and following the relevant safety regulations.

Hello dear, the maximum power that the square wire can withstand is 25A 240V = 6000W, which is 6 kilowatts. The safety regulations for household electrical products now stipulate that the maximum load current per wire usually does not exceed 25A, so the square wire can withstand a maximum electrical load of 6 kilowatts. In the process of use, according to the characteristics of the square wire, the power of the installed electrical appliances should be reasonably distributed, and the maximum amount of 6 kilowatts should not be exceeded, so as to avoid safety accidents such as overheating and short circuit of the wire.

Electrician knowledge: How much power and current can each square wire withstand?

Generally speaking, the resistivity of copper is equal to the resistivity of aluminum, while; So, a square millimeter of aluminum wire is equivalent to a square millimeter of copper wire. The sheath aluminum core wire square is up to 10A and the pipe is 8A, the power w = 220 * 8, the sheath aluminum core is 4 flat, the maximum is 20A and the pipe is 16A, and the power w = 220 * 16

Because the safe interception of square aluminum wire at a temperature of 40 degrees is 20A, it can carry 220V 20A = 4400W in single-phase electric energy, and if the ambient temperature is lower, it can carry more power.

Hello dear, I am glad to answer for you how many kilowatts of power can a square millimeter aluminum wire carry? It is the maximum load of 2200w in line with the wattage It depends mainly on the length and cross-sectional area of the line. Under normal circumstances, a square aluminum core wire passes four currents, and if the line is very long, it will not work, and the number of current commas is smaller.

For example, 220V voltage ear code kilowatt is a current; 380V kilowatt is a current. The square aluminum wire can withstand a maximum current of 10A, and the maximum load does not exceed 2200W, but it should be used in an environment with good heat dissipation and low temperature. Square aluminum wire, overhead safe current carrying capacity is 25A, single-phase usable 5KW.

The safe current carrying capacity of the tube is 15a. Single-phase available up to 3kw.

Only single-phase can band 20kw, only three-phase can band 50 kilowatts, and two groups of 35 square aluminum wires can drive.

In power engineering, the current carrying capacity of a wire is measured in terms of the wire material and the cross-sectional area of the wire (in square millimeters).

Referred to as squared), wire laying conditions are determined by three factors. Generally speaking, a single wire can have a higher current carrying capacity than multiple parallel wires; The open wire laying wire can take a higher current carrying capacity than the wire laid through the pipe; Copper conductors can have a higher ampacarrying capacity than aluminum conductors.

The current carrying capacity of the wire is related to the cross-section of the wire, and is also related to the material, model, laying method and ambient temperature of the wire, etc., and there are many factors that affect it, and the calculation is also more complicated. The current carrying capacity of the various wires can usually be found in the manual. However, with the use of formulas and some simple mental arithmetic, you can calculate it directly, without having to look up the table.
