3 Phase Power Cable Size

Auto will automatically select the smallest cable that meets the three criteria for current rating voltage drop and fault current rating.

3 phase power cable size.

Voltage enter the voltage at the source of the circuit. 1 phase kva volts x amps 1000 1 phase amps kva volts x 1000 3 phase kva volts x amps x 1 732 1000 3 phase amps kva volts 1 732 x 1000. Wire sizing selection tables. Sir we need 70kva power for our office.

40 x 1 25 14 3 50 14 3 67 amps. Items you must consider are. The motor power rate is 55kw 3 phase 380volt. Amperes enter the maximum current in amps that will flow through the circuit.

Select a cable size or select auto. What is the aluminum cable sizing for a 150 kw three phase load 415 volt 0 8 power factor and 6 voltage drop. Three pumps of a pump station 30 10 and 1 horsepower are connected to the power source of 460 volts 3 phase. Single phase voltages are usually 115v or 120v while three phase voltages are typically 208v 230v or 480v.

Thanks and best regards rachmad buchari. Three phase electric power is a common method of alternating current electric power generation transmission and distribution. I have an issue with cable sizing. The number of cores in the cable.

Formulas used in calculator. From table 430 150 they draw 40 amps 14 amps and 3 amps respectively. The type of insulation. I have a motor of pump to be installed at site.

Ignore the neutral and earth conductor in three phase cables. There are several factors that must be considered before determining the proper size wire to select for an application. Single phase 230 volts 230 1 60 three phase 208 volts 208 3 60 three phase 230 volts 230 3 60 three phase 460 volts 460 3 60 warning. 3 phase 5 wire to be taken.

The total cable length is about 130m. Generally there are two phases single phase or three phase. Calculate another variables used things that need to be taken into consideration before computing the cable size and voltage drop. Phase selection the first thing you want is the type of circuit phase you are going to use.

It is also used to power large motors and other heavy loads. A three wire three phase circuit is usually more economical than an equivalent two wire.
