On January 28, the main motor of the extrusion granulation system for the 450,000-ton/year polypropylene unit in the second phase of the 1.2 million tons/year ethylene project at Dushanbe Petrochemical Company, which is under the responsibility of the Tarim Polypropylene Project Department of Jilin Chemical Construction’s Fourth Branch, successfully completed its individual testing run, laying a crucial foundation for the further progress of the project. It is reported that the rated power of this main motor amounts to 16,500 kilowatts. It is not only the most powerful and crucial device among the 155 motors in the entire polypropylene production facility, but it also serves as the sole power source for the production line capable of producing 450,000 tons of polypropylene per year through extrusion and granulation. The equipment uses a single 35 kVA transformer to step down the voltage to 10 kV for power supply, and its weight is 29 tons. During the testing phase, the motor operated continuously and smoothly for 4 hours; key operational parameters such as current, speed, and temperature remained within normal ranges, and all performance metrics met the design requirements, indicating that the equipment’s mechanical installation and electrical insulation systems were fully ready.
