For underground cable CU cable, for 350KW, 6.6 KV. Current derating. Amperes - Enter the maximum current in amps that will flow through the circuit. Now we have to discuss the main topic that’s how to calculate the cable size for motors? M. Maestro. If many cables are grouped together, they will all heat up. Table: Cable Grouping Factor (No of Tray Factor), K2 = 0.68 (for 3 trays having 9 cable each), Let’s select 1.1 KV, 3 core, 240 Sq.mm, Aluminum, XLPE, Armored cable for single run, Technical Details For 1.1 KV, 3 Core, Aluminum/Copper Conductor, XLPE Insulated, Armored Cables, Current capacity of 240 Sq.mm XLPE Armored aluminum cable in Air is 402 Amp, Total derating current of 240 Sq.mm Cable = 402×0.5984 = 240.55 Amp, Resistance = 0.162 Ω / Km and Reactance = 0.072 Ω / Km, Voltage drop, V2 = 0.3 Volts/Km/Amp    (as per Havell’s brochure), Terminal voltage at Motor, V2 = 415 -13 = 402 V, To decide 240 Sq.mm cable, cable selection condition should be checked, Related Post: Servo Motor – Types, Construction, Working, Controlling & Applications. its also depends on the availability of supply voltage,i.e. In most cases 1mm should be fine but depends on how many lights are on the circuit and how long the cable run is. Thus, actual Voltage drop in Volts would be V2 = 0.3*230*200/1000 = 13.8 Volts. Based on the electrician 15kw would be divided by 240volts to give you 62.5amps. The cost of labor for laying of higher size cable will also be higher compared to respective lower size cable. Voltage drop, V2 = 0.3 Volts/Km/Amp (as per Havell’s brochure) = 0.3x217x200/1000 = 13 V I thinks this is wrong, because sysatem voltage is 415v not 217v, So: V2=0.3x415x200/1000 = 24.9v Is that true Sir? MotSize motor databases are frequently updated to always offer the latest available motors. Full technical support available. Load Current = P / (1.732 x V x Pf x Eff)       —>     (P = √3 x Vx I CosΦ = for three phase circuits). Now, here cable length is 200 mtr., so it is divided by 1000 to convert the 200 mtr. Consider these points for calculating 3-phase 15 KW motor at supply voltage of 415V and at 0.8 p.f. Your cable requirements are also unique. The Cable sizes for domestic lighting circuits is usually 1mm or 1.5mm twin and earth cable (aka two core and earth). Determine the minimum size of cable with the reference to IEER 2. Hence nearest higher size 300 sq mm is required. Let’s select 6.6 KV, 3 core, 300 Sq.mm, Aluminum, XLPE, Armored cable for single run, Cable Grouping Factor (No of Tray Factor), K2 = 0.68 (for 3 trays having 9 cable each), Total derating factor = K1 x K2   = 0.88 x 0.68 = 0.5984, Current capacity of 300 Sq.mm XLPE Armored aluminum cable in Air is 450 Amp, Total derating current of 300 Sq.mm Cable = 450×0.5984 = 269.28 Amp, Voltage drop = 0.26 Volts / Km / Amp    (as per Havell’s brochure), Terminal voltage at Motor, V2 = 6600 – 2.132 = 6597.868 V, To decide 300 Sq.mm cable, cable selection condition should be checked. Reply Score 1 for Off Topic: Tornado. High Voltage) or low torque and high torque respectively describe the whole story itself. NO guarantee as to the accuracy of these values is given.
