Successful primary power supply to the substation of China Coal Yulin Polyolefin Plant

Thread Content

On March 27, the 35kV substation of the Spherizone polypropylene plant in the China Coal Yulin Coal Deep Processing Base project, which is under the general contracting of Hualu Company of China Chemical Engineering, successfully received its power supply for the first time. The completion of this milestone marks the successful establishment of the key energy transmission pathway for the project’s facilities. To ensure a successful power connection on the first attempt, the company’s project team carried out thorough planning and careful coordination. They worked together with the client and the supervision unit to conduct in-depth safety and technical briefings, strictly implemented the responsibilities assigned to each position, thoroughly checked the condition of the equipment, and systematically practiced the procedures for power connection. The technical personnel, in accordance with the established plan, carefully checked each key parameter such as the insulation performance of the electrical equipment circuits and the protection settings within the station, thoroughly investigating and eliminating all types of safety hazards to provide solid safety and technical support for power reception operations. During the formal power reception phase, the main transformer, busbars, and high-voltage distribution equipment in the station successfully passed the impulse testing and phase verification tests. The equipment operated stably under load, with all parameters such as voltage, current, and protection responses meeting the requirements specified in the design standards; all operational indicators fulfilled the design requirements. The successful completion of this power supply operation provided a stable and reliable power supply for the individual testing of key equipment such as compressors, pumps, and instrument control systems. Next, the project team will take this as an opportunity to focus on the key aspects of the labor competition, systematically plan and proceed in an orderly manner with all subsequent construction tasks. With a strong sense of responsibility and efficient execution capabilities, they will overcome challenges and fulfill their duties thoroughly, thereby laying a solid foundation for the successful completion of the project and its subsequent operation, and delivering satisfactory results to the company and the clients.
