Based in Hanzhong Economic Development Zone, Shaanxi Province, SEC is a professional integrated enterprise specializing in the research, development and manufacturing of power transmission and transformation equipment. Possessing complete production qualifications and strong technical delivery capabilities, the company’s business scope covers customized R&D, intelligent manufacturing, on-site installation guidance and full-life-cycle services for power transformers, rectifier transformers and various special transformers. With profound technical accumulation and solid industry reputation in power transmission, industrial smelting and new energy grid integration fields, SEC has consistently provided high-quality and reliable equipment support for key major engineering projects across China.
Recently, SEC has successfully manufactured and delivered core power equipment for the industrial demonstration project of collaborative enhanced smelting of lead-based polymetallic solid waste and comprehensive zinc resource utilization. As a key industrial demonstration project under Henan Jinlijin New Industry Co., Ltd., the initiative imposes extremely stringent requirements on the stability, precision and professionalism of core power supply equipment. Customized and ordered by Henan Jinbo Electric Co., Ltd., two sets of ZHSFPT-68500/110 on-load tap-changing rectifier transformers were independently designed and produced by SEC, serving as the core "power heart" that guarantees stable power conversion and continuous operational efficiency for the entire smelting demonstration project.
The customized 110kV on-load tap-changing rectifier transformers act as the pivotal hub of the project’s power supply system, undertaking the critical function of precisely converting high-voltage power and stably transmitting electric energy to the professional smelting production line. Serving as the vital link connecting grid power supply and industrial production, the equipment undertakes 110kV high-voltage grid access and provides stable power drive for downstream smelting facilities. Its product quality, operational stability and working reliability directly determine the project’s commissioning schedule, production efficiency and long-term full-load stable operation.
Throughout the whole project cycle ranging from contract signing, precision manufacturing and factory testing to on-site installation guidance and after-sales support, SEC implemented strict full-process quality control and standardized technical management. By adhering to rigorous production standards and professional service concepts, the company firmly guaranteed the smooth advancement and successful commissioning of the key industrial project. Transforming stable and powerful electric energy into efficient industrial productivity, SEC continuously empowers the high-quality and sustainable development of modern industrial manufacturing industries with reliable power equipment solutions.
