3 Phase Power Cable Size

What is the aluminum cable sizing for a 150 kw three phase load 415 volt 0 8 power factor and 6 voltage drop.

3 phase power cable size. Formulas used in calculator. 40 x 1 25 14 3 50 14 3 67 amps. Select a cable size or select auto. There are several factors that must be considered before determining the proper size wire to select for an application.

Sir i have lode 132 kw three phase witch size mm cable proper work. Voltage enter the voltage at the source of the circuit. Items you must consider are. 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.

Auto will automatically select the smallest cable that meets the three criteria for current rating voltage drop and fault current rating. Amperes enter the maximum current in amps that will flow through the circuit. I have an issue with cable sizing. Three phase electric power is a common method of alternating current electric power generation transmission and distribution.

Wire sizing selection tables. The figure we would plug into the calculator would be. Phase selection the first thing you want is the type of circuit phase you are going to use. Thanks and best regards rachmad buchari.

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. The total cable length is about 130m. What is the minimum cable size to be used.

Three pumps of a pump station 30 10 and 1 horsepower are connected to the power source of 460 volts 3 phase. 3 phase 5 wire to be taken. A three wire three phase circuit is usually more economical than an equivalent two wire. From table 430 150 they draw 40 amps 14 amps and 3 amps respectively.

Sir we need 70kva power for our office. The type of insulation. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. I have a motor of pump to be installed at site.

The number of cores in the cable. The motor power rate is 55kw 3 phase 380volt. Ignore the neutral and earth conductor in three phase cables. Single phase voltages are usually 115v or 120v while three phase voltages are typically 208v 230v or 480v.

For motors it is recommended to multiply the nameplate fla by 1 25 for wire sizing.
