Industry Conference | Jointly Building a New Defense Line for Power Safety: Showcasing at the 2026 Petrochemical and Chemical Digital & Intelligent O&M Summit
Anhui Jinli has been invited to attend the 2026 Conference on Safety, Digital, and Intelligent O&M Technologies for New Power Systems in the Petrochemical and Chemical Industries. Joining industry leaders, the company will discuss opportunities for building new power systems, leveraging its smart lightning protection technologies to empower the high-quality and safe development of the petrochemical and chemical sectors. Centered on the theme "Intelligent Control of New Power, Securing the Cornerstone," this conference brings together leading enterprises—including Sinopec, CNPC, and CNOOC—alongside authoritative institutions such as industry design institutes and research organizations. The event features in-depth discussions spanning 22 core topics, ranging from trends in new power systems and digitalized O&M solutions to key technologies for overvoltage protection. It serves as a premier professional platform within the petrochemical and chemical sectors for exploring issues related to power safety and digital transformation. Deepening Expertise in Lightning Protection Technology: Fortifying the Safety Barrier for the Petrochemical Industry Addressing the inherent characteristics of the petrochemical and chemical industries—such as the presence of flammable and explosive materials, continuous production processes, and complex operating environments—Anhui Jinli has developed a Smart Lightning Protection System. This system facilitates a dual transformation: shifting from "passive protection" to "active defense," and from "decentralized protection" to "fully intelligent protection." Integrating three core modules—lightning early warning, intelligent SPD monitoring, and online grounding resistance monitoring—the system leverages IoT technology to perform real-time data acquisition, analysis, and storage, alongside functions such as multi-level early warning and service life prediction. By establishing a multi-dimensional, full-lifecycle framework for lightning protection and operations & maintenance management, the system effectively safeguards tank farms, plant clusters, electrical equipment, and precision control systems (such as DCS and PLC), thereby mitigating major risks such as fires, explosions, and production stoppages caused by lightning strikes. Integrating Digital and Intelligent Technologies to Empower Industry Security Transformation Currently, the petrochemical and chemical industries are accelerating the development of new-type power systems, with digital and intelligent transformation—alongside the upgrading of safety and operations—emerging as core priorities. Leveraging its proprietary "Nine-Grid Three-Dimensional Protection Technology" as a foundation, Anhui Jinli has deeply integrated lightning protection technologies with the Internet of Things (IoT), big data, and artificial intelligence to craft customized solutions specifically tailored to petrochemical environments. During the conference, the company engag...
