Calculated load = add up the power of each type of equipment KW. Multiply the required coefficient. The required coefficient Kd. Cold processing machine tool set 0.3 Water pump fan air compressor long-term operation 0.7~0.8 Heat treatment furnace set 0.7~0.8 plus the development of each workshop department to calculate the accumulation. = Total calculation load Or what type of enterprise has a table to check. The total demand coefficient is generally (0.3~0.4 industrial manufacturing plant) The power of each equipment is added to about 200 KW. Estimated to use 125~160 kVA transformer (plus development and choose a larger one) according to relevant national regulations ：Oil-immersed transformer overload capacity and time: 10% overload, continuous operation of the transformer for 180 minutes, 20% overload, continuous operation of the transformer for 150 minutes, 30% overload, continuous operation of the transformer for 120 minutes, 60% overload, and continuous operation of the transformer for 45 minutes, 75% overload Can run continuously for 15 minutes
