Can 2 x 120 70 copper conductor cable with 320 kW heater? 10 meters away! 40

There is no problem with the pressure drop of 10 meters between the lines. And what voltage level does your 320 kW heater use? In terms of 320 kilowatts of power.

Single-phase 220V is 1440A current, two-phase 380V is 800A current, three-phase 380V is 480A current, if the design is reasonable, you should use three-phase 380V power supply.

2 x 120*70 copper core cables: "How big are these two cables?" OK, if it is two 120 square copper core cables, its safe current carrying capacity is about 600A, and the heater can be loaded.

If it is two 70 square copper core cables, its safe current carrying capacity is about 475A, so that the load without leaving a margin is barely enough, and the cable cross-sectional area should be increased for safety reasons.

If it is a 120 plus a 70 copper core cable, its safe current carrying capacity is about 537A, which can load the heater.

Mine, are you still satisfied?

3x70 plus 1x35 copper cable, 100 meters distance, how many kilowatts can be driven at most.

Can the 3x70+1x35 square cable aluminum orange rubber wire come out of the special transformer with a length of about 90 meters (overhead) and a three-phase balanced load (all motors) with 150kw? A: No, you cannot.

Analysis: 1. The overhead volt-round 3x70 ten 2x35 square aluminum core cable can theoretically carry 90 kilowatts. 75kw is appropriate.

2. YJLV22 3X70+2X35 25 when the soil laying current carrying capacity is 175A, and it can be 110KW at this time; At 25 hours, the current carrying capacity of air laying is 155a, and 95kw can be carried at this time. Wire and cable: Wire and cable are wire products that transmit electrical energy, electrical signals and realize electromagnetic energy conversion.

Cables usually consist of a core that transmits electricity or signals and a sheath that protects and insulates them. Cables that contain only one core and are thinner in diameter are often referred to as wires. There are also wires that are not insulated and are called bare wires.

The core in the cable is made of a metal material with good conductivity, usually copper (good conductivity) or aluminum (less costly). Wires and cables in a broad sense are also referred to as cables, and cables in a narrow sense refer to insulated cables. It can be defined as a collection of the following parts:

one or more insulated cores, and the packages that each of them may have.

Hello dear! Glad for your question! 3 times 50 plus 1 by 25 copper core cable 100 meters long can carry how many 220 volt electrical kilowatts:

The length of 3*50+1*25 copper core cable with a length of 225 meters can band 87kW and the current is 155A. Check the following table, it can be found that the safe flow rate of 3*50+1*25 copper core cable when laying and removing oranges is 155a. Copper cable voltage loss:

Distance: l 225m Copper wire resistivity:

The cable has no good cross-sectional area: s=50mm. Resistance of the cable:

r l s = the voltage drop of the cable is: u ir = the voltage loss rate of the cable: 12 380 = the urban distribution network planning and design code stipulates that the voltage fluctuation requirements of 380V are between +5% and -7%.

The voltage loss is within the requirements of the specification, and the power can be calculated according to the current of 155A: p = calculated according to the three-phase mains, and the power factor is taken.

Summary. Hello, I am glad to answer for you, your question How many kilowatts can 3*25+1*16 copper core cable carry from 200 meters The answer is: the answer is 3x25 ten|The copper core cable of X16 can carry kilowatts, and the safe current of each square is 5A for more than 10 square meters and less than 50 square meters, and 5A times 25 to get 125A

How many kilowatts can be carried by 3*25+1*16 copper core cable at a distance of 200 meters.

Hello, I am glad to answer for you, your question How many kilowatts can 3*25+1*16 copper core cable carry from 200 meters The answer is: the answer is 3x25 ten|The copper core cable of X16 can be rolled into the belt kilowatts, and the safety current of each square meter above 10 square meters and below 50 square meters is 5A, and 5A is multiplied by 25 to obtain 125A

The safety current of the line should be 2 times the load current, 125A divided by 2, according to the formula, the power is equal to the root 3 times the voltage 380V times the current multiplied by the coefficient of the power and the rate coefficient of Sakura and 31250 watts, 31250 watts is equal to kilowatts, so 3 25 ten ridge traces 1x16 copper core cable can be with kilowatts.

It is recommended to use it within the safe range of electricity consumption.

Each phase can drive thousands of buckets to open the empty silver tile, the three-phase combination next to the reed meter is kilowatts, and the voltage drop when fully loaded is volts.

Estimated by the empirical formula for kilometre square amperes: 50

How many kilowatts can a 3*120+2*70 copper core cable carry.

Hello, 3 x 120mm and 2 x 70mm copper core cables can withstand 165,000 watts or 165 kW of electrical power. First, you need to calculate the total cross-sectional area of the copper core cable. Assuming that the 120mm and 70mm copper core cables have the same virtual length, they can be calculated as follows:

Total cross-sectional area = 3 x 120mm +2 x 70mm =360mm +140mm =500mm Next, you need to know the current rating of the cable to calculate the power it can withstand. Normally, cable specifications and current ratings can be read from cable markings, but if there are no markings, the following formula can be used to estimate: current rating = total cross-sectional area x therefore, current rating = 500mm x = 750 amps.

Finally, the following formula can be used to convert the current to the power it is withheld: Power = Current x Voltage x Power FactorAssuming that the power factor of the cable is 1 (which means that the power factor is 1 and there is no power loss), then the following formula can be used: Power = Current x Voltage If the voltage is 220 volts, then the work coarse reputation rate = 750A x 220V = 165,000 watts Therefore, 3 x 120mm and 2 x 70mm copper core cables can withstand 165, 000 watts or 165 kilowatts of electrical power.

Summary. *35+1*16 copper core cable, can carry a load of about 60 kilowatts. 2. Take copper wire as an example: check the rated ampacities of the current carrying capacity meter to know that the rated ampacities of 35 square cables are about about per square meter.

4 How many kilowatts can a 35 copper core cable carry when it is 200 meters away.

*35+1*16 copper core cable, can carry a load of about 60 kilowatts. 2. Take the copper nuclear hand early line potato wheel as an example: check the rated ampacities of the 35 square cables, and the rated ampacities per square are changed from left to right.

How many kilowatts can be carried by dividing into 3 220V?

Through the calculation, you can get 220 volts of rubber base, which can carry 5500 watts, and even 8000 watts, of course, the lowest can support 1600 watts.
