    With a power of 120 kilowatts and a voltage of 380 volts, a cable with a cross-sectional area of 76 square is required.

    According to the inscription, it can be known:

    The working current is about: 228A

    Wire selection area: s=228 3=76

    According to the cable specifications, copper cables should be selected: 3*95+1*70.

    Division calculations:The product of several numbers is divided by a number to divide any factor in the product by that number and then multiply by the other factors. For example: 8 72 x 4 9=72 9 8 4=256.

    The sum of several numbers divided by a number allows each additive number to be divided by this number separately, and then the quotient is added. For example: (24+32+16) 4=24 4+32 4+16 4=18.

    The rated current of 120kw i=p ampere.

    If it is in close proximity (within a few tens of meters), the copper cable is 50 square millimeters and the aluminum cable is 90 square millimeters.

    If it is a long distance (more than 100 meters), the copper cable is 90 square millimeters, and the aluminum cable is 150 square millimeters.

    If it is between close distance and long distance, the copper cable is 70 square millimeters and the aluminum cable is 120 square millimeters.

    The power is 120 kilowatts, the voltage is 380 volts, and the operating current is approximately: 228A

    Wire selection area: s = 228 3 = 76 square millimeters of copper wire.

    According to the cable specifications, copper cables should be selected: 3*95+1*70.

    The power is 120 kilowatts, the voltage is 380 volts, and the operating current is approximately: 228A

    Wire selection area: 3 * 95 + 1 * 50 copper core cable.

    If it is farther, increase a specification: 3*120+1*70 copper core cable.

    Or the copper wire can be, if it is far away, it is recommended to use a square of a certain brand socket, a meter eight wire, with a wire can bring 2200w.

    The total power of three-phase four-wire is 300kw, how many square cables do you need to use?

    Hello dear, the total power of three-phase four-wire is 300kw, how many square cables do you need to use? 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: slag rate; u:

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

    According to the wire current comparison table, at least 240 square meters of copper core wire should be selected for 300kw load. The 240 square copper core wire is laid with a safe interception flow of about 570a. I hope mine can help you like that; Once again, I wish you good health and a happy mood! 

    The total power is 380kw, Q: How big square of cable to use.

    Hello dear, 380 kilowatt motor needs 150 square meters of copper wire single-phase three-phase? Three-phase, 380x1000 3 10000 = amps. That is, you can use square copper wire to field shirts.

    3*150+1*70 The safe current carrying capacity of the large cross-section copper core wire per square is about, and the wire cross-section is required: S 1368 3 456 (square), and the cable specification can be selected

    3*150+1*70。The safe current carrying capacity of the copper core cable is slightly larger than that of the aluminum core, and the selection of the cable can be one size smaller than the aluminum core cable, and the line loss is generally not considered, and the starting current of high-power electrical appliances should be considered. If all the 130kw total power is used at the peak, and there is a high-power electrical appliance with a cavity, you may wish to consider a larger cable, and the starting current of the general motor is 3-5 times of the current in normal use.

    Glad to be able to your questions. Need 3*150 square town tour + 1 70 square four-core cable. Current of 380kW load (in COS):

    I p large cross-section copper core wire per flat Yu hidden pin side of the safe current carrying crack, wire cross-section: S 1368 3 456 (square) cable specifications can be selected: 3 * 150 + 1 * 70

    The electrical equipment is 220V, using three-phase four-wire power supply, with a total power of 120 kilowatts, and how big a cable is needed.

    The electrical equipment is 220V, using three-phase four-wire power supply, with a total power of 120 kilowatts. Hello, happy to answer your <>

    Pro: 120 kW to use 2 square wires and 500 mA air switch. If the load is single-phase 220 volts, YJV or YJLV series copper wire uses 240 square [current carrying capacity 587 amps], aluminum wire uses 300 square [current carrying capacity 527 amps].

    1. Three-phase electricity: power = (root number 3) voltage power factor current [the calculation result is about 380A, choose the air opening of 400A]. 2. Two-phase electricity:

    Power = voltage and current [the calculation result is about 910A, select 1000A air opening]. Extended Information: Air Switch Operating Conditions:

    Ambient Air Temperature: +40 for the upper limit of ambient air temperature; Lower limit of ambient air temperature -5 ; The average value of the ambient air temperature for 24h does not exceed +35. Altitude:

    The altitude of the installation site does not exceed 2000m. Atmospheric conditions: The relative humidity of the atmosphere does not exceed 50% at the ambient air temperature of +40; It can have a higher relative humidity at a lower temperature; The average monthly maximum relative humidity of the wettest month is 90%, while the monthly average minimum temperature for that month is +25, taking into account condensation on the product surface due to temperature changes.

    Hope mine can help you <>
