    High voltage side: 15kva ( Low voltage side: 15kva (This is the high and low voltage rated current, if you are applying for electricity, you should consider how big your load is (1, how many kw, how much three-phase load, how much single-phase load, 2, after estimating the total load, but also consider the utilization rate of the load, for example:

    The total load of a unit equipment is 100kw, and the working system is two shifts, so the utilization rate is calculated, if there will be a situation where the equipment is opened, or even the equipment is fully open, the cable needs to be laid according to the utilization rate of 1 3, and the power factor should be considered) This is calculated according to the load of the existing equipment, the selection of cables should not only consider the economy, but also consider the safety, try not to overload the operation, if there is a possibility of increasing the load, the cable should also leave a margin.

    Fifteen kilowatt asynchronous motors.

    With a rated current of 30A, you can choose a 6 square copper cable. If you often run at full power, choose a 10 square one.

    Hello, dear <>

    The four-core 16-squared cable can carry about 25 or 38 kilowatts. The 16 square cable, calculated according to the power voltage of 380V, is the current carrying capacity of the aluminum core wire is 64A, and the carrying power is 64X380 1000=. The current carrying capacity of the copper core wire is 100A, and the carrying power is 100x380 1000=38KW.

    The greater the current through the line, the more electrical power is delivered. The current carrying capacity refers to the amount of current transmitted by the line wire. The maximum allowable ampacity of each type of wire is specified in the national specification.

    When in use, the maximum load current required for the load must be less than the long-term allowable current carrying capacity of the wire in the air. I hope my answer is helpful to you, and finally I wish you good health and a happy mood again! <>

    Dear, hello, I am glad to answer for you A 16 square copper cable can be with 51 kilowatt three-phase circuit. The 16 square copper core wire can carry about 51 kilowatts in a three-phase circuit. You can calculate according to the formula p=.

    The wheel height is 16 square meters, and the safe carrying current of the copper core electric combustion line is 91A, single-phase circuit. If a 16 square copper core wire is used in a single-phase circuit, it can carry about 20 kilowatts.

    Current 115 amps with 50 square cables.

    50 square level.

    The cable belt is 65 kilowatts, which is 115 amps. If it is a copper core three-phase four-wire system of 50 square liquid spring socks mm.

    The cable can be with kilowatts. According to the safe ampacity of the wire.

    50 copper cables can carry 106 kilowatts, and 50 square copper wires can carry the safety of the electric sensen which flow is 191a.

    The wire is also divided into copper wires, such as Lv wire: the current carrying capacity of aluminum wire per square millimeter is 3 to 5 amperes, so the maximum ampacities of 16 square aluminum wires can reach 80 amps, and if laid in a single-phase circuit, the voltage is 220 volts, which can reach kilowatts. in three-phase circuits.

    , the voltage is 380 volts, so it is able to withstand a power of 42 kilowatts.

    When buying aluminum wire, you first need to look at its packaging bag, which generally has a certificate, which will indicate what specifications it is and what its voltage is. Including the date of manufacture, as well as the manufacturer, etc., this information is very complete.

    Devices with a total power of 15kw require square copper core cables.

    Calculation of equipment current with a total power of 15kw: three-phase: p=

    p: power; u: voltage; i: The current is highly respected; COS: power factor, 1 for resistive load, 1 for inductive (such as motor) load;

    Root number 3=; i=p/(

    According to the relationship between wires and cables and safe current carrying capacity, it is known that equipment with a total power of 15kw requires a square copper core cable.

    To determine the required cable size, there are several factors to consider, such as current load, cable length, ambient temperature, heat dissipation and loss of the cable, etc. Generally speaking, the determination of cable size is based on the technical specifications and electrical design standards provided by the cable manufacturer.

    Assuming that you need to transmit three-phase electricity, and the operating voltage is 400 volts, and the power supply is 135 kilowatts, you can use the formula for the sliding surface to calculate the required cable cross-sectional area

    Cable cross-sectional area = 135,000 400

    Among them, is the coefficient of three-phase electricity, 400 is the working voltage, is the power factor, is the safety factor of the cable.

    According to the above formula, the required cable cross-sectional area is about 161 square millimeters. It is important to note that this is only a rough estimate and may be adjusted on a case-by-case basis. In addition, when installing cables, it is also necessary to consider the way the cables are laid, supported and protected measures.
