How big cable is used for 200 kilowatts, how big is a cable for 200 kilowatt loads Do you know

If it is 220V50Hz, 200 kW needs to be used in square millimeters.

of copper cables. If it is 220v50hz, 200 kilowatts need to use square millimeters of copper cable.

The calculation is as follows:

p=ui,i=p u=200000 220=safe current density of copper wires.

It's 8a mm

Cross-sectional area of copper wire = square millimeters).

90 square meters of cable wire is required.

1) Calculation Method:

According to the formula for calculating the three-phase electric phase current i=p (u p - power (w); U-Voltage (380V); cos - power factor (; i-Phase current (a).

Bring in data p=200kw, u=380v;

The phase current i = 357a.

2) In a three-phase balanced circuit, the safe ampacity of the aluminum wire is 3 5a mm2.

357 5=, the nearest specification of the cable is 90mm2.

Inductive load 200 kW.

The current is, if it is a single-core copper core cable, 120 square meters are required, and its cut-off current is; If you use a three-core copper core cable, you need a 240 square copper core cable, and its cut-off is more than buried laying, and when the cable model is VV29, the cut-off rate of different grades of cable is different).

200kw is about 400A current, 3-phase power supply, with copper core cable, the current density of the cable is calculated by square millimeters, 400, according to the cable specification should choose 3 95 + 1 50 rubber cable, this is the safest cable configuration, considering that all equipment can not work at the same time, so the use of 3 70 + 1 35 copper core rubber cable can also be, but it must be a national standard cable, or with 3 95 + 1 50 aluminum core cable is also OK.

The distance, the temperature should be increased appropriately.

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

1. It is recommended to use a 3x95mm2 electric cable.

kw load, approximate current.

The square cable has a current carrying capacity of 375A in air and 380A in soil.

4. The calculated load is also called the required load or the maximum annihilation load. A calculated load is an imaginary continuous load with a thermal effect equal to the maximum thermal effect resulting from the actual fluctuating load over a certain period of time. In the power distribution design, the maximum average of 30 minutes is usually used as the basis for selecting the conductor of the electrical industry according to the civil heating conditions.

90 square meters of cable wire is required.

1) Calculation Method:

According to three-phase electricity.

The formula for phase galvanometer is i=p (u

p-power(w); U-Voltage (380V); cos - power factor (;

i-Phase current (a).

Bring in data p=200kw, u=380v;

The phase current i = 357a.

2) In the three-phase balanced finch touch circuit, the safe ampacity of the aluminum wire is 3 5a mm2.

357 5=, the nearest specification of the cable is 90mm2.

If it is 220V50Hz, 200 kW needs to use a square millimeter copper base cable.

The calculation is as follows:

p=ui，i=p÷u=200000÷220=

The safe current density of copper wire is 8a mm

The cross-sectional area of the copper wire is rented = square millimeters).

At a voltage level of 380V:

The total power is 200kw, the power factor is taken, and the line current: i=p 3*380*check the table: aluminum core cable with 185 square millimeters.

Copper core cable with 120 square mm.

The load distance (overhead line) is calculated first

Load distance = power * length = pl

p = power (kw).

l Length (km).

Hello, if the distance is not far (less than 200 meters), the total power of 200kw can choose 150 square copper core cable, but there is no margin, it is recommended to use 185 square copper core cable 200kw load, call Huaizi flow. The cable of 185 square meters has a current carrying capacity of 375A in air and 380A in soil.

Summary. Hello dear, how big cable is used for 210 kilowatts 210 kilowatts of power, and in the three-phase circuit, the voltage is 380 volts, and the cable specification of the configuration must reach 240 square copper wires to meet the needs of such a large power. So we can directly through the power and voltage, to get its safe current carrying capacity is about 375A, if the configuration is a copper wire, we must choose such a large specification.

If the configuration is an aluminum cable, yes.

Hello dear, how big cable is used for 210 kilowatts 210 kilowatts of power, and in the three-phase circuit, the voltage is 380 volts, and the configuration of the cable specification must reach 240 square copper wires to meet the needs of such a large power. Therefore, without sail, we can directly pass the power and voltage, and get its safe current carrying capacity is about 375 amperes, and if it is a copper wire, it is necessary to choose such a large specification. If the configuration is an aluminum cable, yes.

The length is 260 meters and is buried in the soil.

Yes, dear, I hope I can help you.

210 kilowatts with 150 square copper cable, i=p ( 210 (according to the three-phase mains calculation of slow commotion, power disturbance rate factor check the following cable ampacity table, it can be seen that the 150 square copper cable corresponding to the safe ampacity (in the air) is 399a, so the three-core copper cable of 150 square brigade can be selected. You look at this algorithm, right.

Yes, that's right. That's like me, the length of 260 meters buried in the soil 380V cable is more suitable.

Yes, dear, I hope I can help you.

Summary. 120 square copper wire can be used. The 120 square copper wire cable can withstand the maximum rated current of 720 amperes, the maximum power that can withstand is kilowatts, and the maximum power that the three-phase can withstand is kilowatts, which is far greater than the rated power of the motor of 210 kilowatts, which can ensure the normal use of the motor and ensure that the power consumption of the circuit will not be overloaded.

120 square copper wire can be used. The copper wire cable of 120 Ping Xun Burning Fang, the maximum rated current that it can withstand is 720 amperes, the maximum power that can withstand is kilowatts, and the maximum power that can be withstood by three-phase is kilowatts, and the rated power of Yuanzhen Changpi is much greater than the rated power of the motor of 210 kilowatts, which can ensure the normal use of the motor and ensure that the power consumption of the royal circuit will not be overloaded.

The length is 260 meters and is buried in the soil.

Copper wire? Yes, with a 4+1 cable.

260 is OK.

Copper wire withstands better.

Could you please help me calculate how big the cable and empty it is.

210 kilowatts with 150 square copper cable, i=p ( 210 (which difference core = 375a (calculated according to the three-phase mains, the power is calculated by the number of rounds Check the following cable ampacity table, you can know that the safe ampacity (in the air) corresponding to the 150 square copper cable is 399a, because Li Di can choose 150 square three-core copper cable.
