How big a wire is used for a power of 35KW?

The rated current of 35kw electrical equipment i=p 3 u cos =35. (Voltage U = Power Factor Cos Press.)

Choose 3 16 + 1 10 copper core cable (safe ampacity : 68a) or 3 25 + 1 16 aluminum core cable (safe current carrying capacity 71a).

Use rubber insulated wire: copper wire 10mm??(safe ampacities 69a), aluminum wire 16mm (safe ampacities 69a).

3000W should be used wire grid is within 100 meters, the starting current is considered by double, 35kW single load, 16mm copper core cable should be selected.

35kw 25kw 15kw equipment need how big wires and switches: this can be according to the formula; Power = voltage 3 times the root number multiplied by current multiplied by power factor.

I don't know what device you are, the power factor is calculated as 1. 35*1000/（

35 kilowatts use 25 square aluminum wire, 25 kilowatts and 15 kilowatts use 16 square aluminum wire switch.

1.It is enough to use a load cable, there is no need to use an armored power cable; 35kw can be used 25 square, 22kw can be used 16 square, 11kw can be used 6 square, each 3kw can be used or 4 square, (all refer to the motor connection line).

2.How much should a 35kw, a 22kw, an 11kw, and three 3kw motors be selected? Is it OK to have a 400a? (There are two cases: simultaneous operation and non-simultaneous operation).

Answer: If it is running at the same time, the total operating power is 87kw, if it is a motor, the total current should be about 180A, considering that it will not be started at the same time (that is, at the same time), the total load air switch has 250A is enough, there is no need to use 400A, but each motor should have a separate starting and control circuit. This refers to the total load side, and if it is a total power control, it is also possible to use 400A.

The total power of electricity is 35 kilowatts, and 380v should be selected as 16 square metersCablesand Empty Open.

Three-phase current = power, voltage, power factor.

Generally left and right).

That is, the current = 35000 380 or so to tell and know.

Copper wire cables of 16 square meters or more can be selected.

Safe ampacity.

Generally, the safe ampacity of copper conductor is determined according to the allowable maximum temperature of the core, cooling conditions and laying conditions. Generally, the safe current carrying capacity of copper wire is 5 8a mm, and the safe current carrying capacity of aluminum wire is 3 5a mm.

Key points》The safe ampacity of the general copper wire is 5 8a mm, and the safe current carrying capacity of the aluminum wire is 3 5a mm. Such as: mm socks elimination bvv copper wire shed slag safe current carrying value recommended value, 4mm bvv copper wire safe current carrying value 4 8a mm = 32a.

35 kW 220 volts with square copper wire. 35000 watts 220 volt amps.

The carrying current of 1 square copper wire is 5 amperes.

Amps 5 amps squared.

In order to make the alternating current have a very convenient power conversion function, usually the power transmission is in the form of three phases and four wires, the three ends of the three-phase electricity are called phase wires, and the three tails of three-phase electricity are connected together and called neutral wires, also called neutral wires. The reason why it is called the zero line is that there is no current passing through the neutral line at the time of three-phase equilibrium, and then it is directly or indirectly connected to the earth, and the voltage difference between it and the earth is close to zero.

The earth is a good conductor, and the ground wire is short-circuited to the earth through a deeply buried electrode. The transmission of mains power is in a three-phase way, and there is a neutral wire, the current of the neutral wire is zero when the three-phase balance, commonly known as the neutral line, another feature of the neutral line is that it is short-circuited with the ground wire in the total distribution input of the system, and the voltage difference is close to zero. The three phase wires of three-phase electricity have a voltage of 220 with the neutral wire, which will produce an electric shock to people, commonly known as the live wire.

Just take this power voltage as current.

35000 220 = 159A current.

You can use copper core wire of 50 square meters or more.

Summary. Hello.

If it is a voltage of 380, two cables of 240 are connected in parallel, and if it is 660, two cables of 185 are connected in parallel, both are copper wires.

How much cable is used for 440kw electric power.

Hello, I'm sorting out the answers to your questions, please wait a while Okay! Cables are laid in the ground, within 100 meters.

Hello, the three-phase 380 volt 440 kW should be used in parallel with 4 VV22 aluminum core cables of 3x120+1x35mm.

I want to use copper core cable, how many square meters?

Hello. If it is a voltage of 380, two cables of 240 are connected in parallel, and if it is 660, two cables of 185 are connected in parallel, both are copper wires.

For 300kw load, at least 240 square copper core cables and 360 square aluminum core cables should be selected.

Calculation steps: p=, i=p (

p: power; u: voltage; i: current; COS: Power factor, 1 for resistive load, and 1 for inductive (such as motor) load.

For 300kw load, at least 240 square meters of copper core wire should be selected, and the safe interception flow of 240 square copper core wire open wire is about 570A.

Usually people need to install wires of different power according to the electricity needs of different locations when designing lines, today I want to share with you how big wires are used for 15kw380v and how to choose household wires, friends who want to know may wish to take a look at it together!

1. How big wire is used for 15kW380V.

15kW380V with 25mm aluminum cable, 16mm copper cable. The calculation of three-phase current is: current = power voltage voltage phase load power factor.

Second, how to choose household wires.

1. Look at the packaging.

When choosing wires, the first thing to see is whether the wire reel type is neat, whether the packaging is complete and good, whether the certificate is closed, whether the trademark, factory name, factory address, specifications, cross-section, and printing are clear. Try to choose the wires produced by large manufacturers, because the production of large manufacturers is produced in accordance with the relevant national standards, so the quality is also guaranteed.

2. Compare the cores.

You can open the package, look at the wire core inside, compare the wire core of different car brands, and pull the wire skin with your hands, if it is not easy to tear, it means that it is the national standard.

3. Burn with fire.

The insulating material is ignited, and the fire is extinguished within 5 seconds, if there is a certain flame retardant function, it will help the national standard line.

4. Look at the inner core.

Looking at the copper material of the inner core of the wire, the brighter and softer the copper quality, the better. Usually, the inner core required by the national standard must be made of pure copper.

5. Look at the online printing.

Usually the wires specified by the state will be printed with relevant logos, including: product model, unit name, etc., and the maximum interval between the logos will not exceed 50 cm, while the printing is clear, the interval is symmetrical, and the national standard line produced by large manufacturers meets these conditions.

Summary: The above is for you to share 15kw 380v with how big the wire and how to choose household wires, I believe you have a corresponding understanding after reading the above sharing, I hope the above sharing can help you, if you need to learn more about relevant information, please continue to pay attention to Qeeka Home**, will answer for you one by one.
