For 100kw which cable size is good and how to find out cable size?

100 kw is the power drawn by the load. to calculate the cable size you need to know the voltage. From that you can calculate the current. this decides the cable size. for example if the voltage is 400Volts then the current flowing in the circuit when the load is 100 KW will be 250 amps. (100,000/400). for 250 amps to flow with out causing excessive heating of the cable the cross sectional area of the copper cable should be 150 sq mm.for a round cross section the diameter will be roughly 15mm.


What is the internal resistance 6.6 kw load?

You need to know the voltage and the power factor in order to answer the question.


Can a 400 kw generator handle a 460 kw load?

Since the breaker that is installed on the generator set will be sized to the output of the 30 kW generator, the load will stay connected until the thermal trip of the breaker trips the load off line. This will be in the matter of seconds before it happens. To handle a 75 kW load and depending if it is an inductive or a resistive load you will need at least a 80 to 100 kW generator.


For 225 kw motor what is the amps star and delte and what is the cable size required?

Need to know what the voltage of the motor is.


What is the cable size of 110 KW motor?

The cable size depends on a few factors, such as the supply voltage, the method of starting the motor, (direct-on-line, or star delta) and the length of cable required to compensate for voltage drop. Also, if the cable is copper or aluminum.110 kW motor has a rated current of 200 amps at 415 volts, so the correct copper cable size would have a cross-sectional area of 75 square mm., if the motor is started direct-on-line.At 660 volts, the rated current would be 118 volts and the cable size would be 35 square mm.

When using an external resistive load bank to test an engine driven generator do you load it to kVA or KW?

It does not matter, when testing a generator with a resistive load bank, if you load it to kVA or KW. For a resitive load, i.e. non-reactive load, the power factor is one, so kVA and kW are the same.

How many alternator generator turbines will it take to run a full household?

It depends on the total connected load (KW) of the house. If the total connected load is about 20 KW the alternator generator should be designed to meet peak 20 kw load


What is the cable size to take a load of 95kw?

It depends on the voltage, which was not specified. Please restate the question, giving the voltage. The reason for this is that cable size is a function of current, not power.AnswerThe size of a cable depends on the material from which the conductor is made, the number of cores, the type of insulation, whether it is armoured or unarmoured, and how it is installed. So, even if you know the relevant voltage, the only way in which you can determine the correct cable size is the use the tables provided in your country's wiring regulations, which take these factors into account. Incidentally, the symbol for 'kilowatt' is kW, not 'kw'.

How thick is the cable to conduct 22.5 kw of power?

Cable doesn't conduct power, it conducts current. Either the voltage and load must be known or the amperage the cable will need to conduct to determine the size of the cable. Once the amperage is known, there are multiple tables online that have cable size and amperage. Do a Google search for "conductor amperage" for examples.
