Can the 220 watt motor aluminum core cable 3 240 1 be brought up

220 watt motor?? It should be a 220 kilowatt motor! The current is about 440A, and it cannot be brought up for aluminum core and specification 3 240 + 1 120 cables.

Because: 3 240+1 120 aluminum-core XLPE insulated PVC sheathed power cable, laid in air, long-term allowable current carrying capacity: 356 amperes.

3 240+1 120 aluminum-core PVC insulated PVC sheathed power cable, laid in air, long-term allowable current carrying capacity: 299 amps.

It can be seen that the current carrying capacity cannot be satisfied.

Requires 3 240+1 120 copper core XLPE insulated PVC sheathed power cable, or.

3 300 + 1 150 copper core PVC insulated PVC sheathed power cable can meet the requirements.

The 3*50+1 aluminum core cable can drive the three-phase motor (motor 45 kW) started by the star delta

The 3*50+1 aluminium core cable allows a continuous current carrying capacity of 90A to 120A45 kW motor current I 45

Star triangle start is possible.

It should be a 220 kilowatt motor! Aluminum core cable 3x240 +1 can be brought up! However, it is best that the line is no more than 300 meters away from the transformer.

When choosing a cable, you need to consider factors such as the rated bridge lap of the cable, the rated voltage of the sensitive hole and the material of the cable. If the rated current and rated voltage of the cable meet the requirements of the motor, then it is possible to use a 240 square millimeter aluminum core cable before trembling. Specifically, if your 200 kW motor is rated at 380V, then the required cable cross-sectional area can be calculated based on the relationship between the rated current of the motor and the resistance of the cable wire.

In general, the cable cross-sectional area should be greater than or equal to the calculated required cable cross-sectional area to ensure that the cable can withstand the required current load. It should be noted that the resistance of aluminum core cable is greater than that of copper core cable, so when using aluminum core cable, it is necessary to choose the appropriate cable cross-sectional area to ensure that the cable has sufficient conductivity and safety performance. At the same time, it is also necessary to pay attention to the connection and maintenance of the aluminum core cable to ensure the normal use and safety of the cable.

。According to the three-phase phase current calculation formula P=i U, the maximum safe ampacity of 240 square aluminum core wire is 260A, and the data of Minting Hall with Yu macro input data I=260A, U=380V, COS = square aluminum core can withstand the maximum load P=260 380, so the 240 square aluminum core cable three-phase four-wire can load kilowatts.

240 aluminum core cable is a common power transmission line and one of the commonly used low-voltage cables. It has a rated voltage and the conductor is composed of an aluminum core and polyethylene insulation. Depending on the power used by the wire and cable, the 240 aluminum core cable is capable of transmitting multiple kilowatts of electrical energy.

Generally speaking, 240 aluminum core cable is usually used for low-power power transmission lines, with a rated current of 225A, which means that the electrical power it can transmit will not exceed 225KW. If we need to transmit more electrical power, we need to use larger size cables, such as 400 aluminum core cables, 630 aluminum core cables, etc.

It should be noted that compared with copper core cables, aluminum core cables need to have a larger cross-sectional area due to low conductivity, resulting in larger and heavier wire and cable volumes, resulting in greater space for wires and cables, but also cheaper. Therefore, when choosing to use wires and cables, it is necessary to choose the appropriate specifications according to the actual needs, and the relevant norms and standards need to be followed in installation, repair and maintenance.

To sum up, 240 aluminum core cable has a wide range of applications in low-power power transmission occasions, it can transmit a certain amount of electrical power, but it is necessary to pay attention to the actual needs and appropriate specification selection when using. We should improve our understanding of wires and cables, and correctly select the right wires and cables to ensure the normal use and safe operation of the power system.

Kw. When we use wires, we must take into account the power of the electrical appliances we use, and try to choose those high-power wires. Because you can't use high-power appliances now, it doesn't mean that you won't be able to use them in the future.

And the use of high-power wires is also very reassuring, so that the use of electrical appliances will cause a short circuit or power failure, some people still do not understand such a truth, thinking that the wires are the same, anyway, they can be lit. Such a notion is very wrong and needs to be corrected.

The reasons why 240 aluminum wire can bring kilowatts are as follows:

It can be calculated directly through the calculation formula of the email, we know that the voltage and the rated current of the code can be calculated directly, the maximum current occupation of the 240 median aluminum wire is 260 amps, the power factor is, and the voltage is 380 volts, and the three data can be multiplied directly.

The power that 240 aluminum wire can bring is also relatively large, but it must be lower than the kilowatt in the process of use, so as to ensure the safety of the circuit and not be prone to safety hazards. <>
