3 Phase Power Cable Size

What is the minimum cable size to be used.

3 phase power cable size.

The total cable length is about 130m. Three phase electric power is a common method of alternating current electric power generation transmission and distribution. For motors it is recommended to multiply the nameplate fla by 1 25 for wire sizing. Ignore the neutral and earth conductor in three phase cables.

3 phase 5 wire to be taken. Sir we need 70kva power for our office. What is the aluminum cable sizing for a 150 kw three phase load 415 volt 0 8 power factor and 6 voltage drop. Generally there are two phases single phase or three phase.

The motor power rate is 55kw 3 phase 380volt. There are several factors that must be considered before determining the proper size wire to select for an application. Select a cable size or select auto. I have a motor of pump to be installed at site.

40 x 1 25 14 3 50 14 3 67 amps. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. Formulas used in calculator. Items you must consider are.

Thanks and best regards rachmad buchari. 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.

Three pumps of a pump station 30 10 and 1 horsepower are connected to the power source of 460 volts 3 phase. Calculate another variables used things that need to be taken into consideration before computing the cable size and voltage drop. A three wire three phase circuit is usually more economical than an equivalent two wire. Auto will automatically select the smallest cable that meets the three criteria for current rating voltage drop and fault current rating.

I have an issue with cable sizing. From table 430 150 they draw 40 amps 14 amps and 3 amps respectively. Amperes enter the maximum current in amps that will flow through the circuit. The type of insulation.

It is also used to power large motors and other heavy loads. The number of cores in the cable. Single phase voltages are usually 115v or 120v while three phase voltages are typically 208v 230v or 480v.

Phase selection the first thing you want is the type of circuit phase you are going to use.
