Blazing a Trail, Rowing Toward the Future
As spring gives way to summer, Jinli Lightning Protection’s first-half team-building retreat kicked off right on schedule. The entire team headed to Lujiang to embark on a one-day outdoor adventure themed: "Blazing a Trail, Rowing Toward the Future." Leaving behind the hustle and fatigue of work, we set out with light hearts—ready to enjoy a truly joyful and exhilarating team journey! In the morning, we gathered at the outdoor grounds of the Lujiang Gotion Hotel. Beneath a clear, boundless sky, we teamed up to tackle a series of fun-filled challenges. The Roman Catapult team exerts its collective strength, aiming at the target with seamless coordination. Archery Tag: A high-octane clash—where the interplay of offense and defense reveals true responsibility. Moving the yoga ball requires unity of heart and perfect synchronization; only by maintaining a consistent pace can we advance steadily. Every task demands a division of labor and mutual support; everyone fulfills their respective duties and cooperates fully, and amidst laughter and cheers, we engrave the very essence of "team" into our actions. In the afternoon, we arrived at the picturesque Jintang Lake Wetland Park. The azure waters mirrored the blue sky; and although the wind and waves were strong, they could not dampen everyone's enthusiasm. Under the guidance of professional instructors, we received comprehensive onshore training—covering everything from paddle grip and steering to forward and backward maneuvering—enabling everyone to quickly master the basics and take to the water for practice. Although the wind and waves were significant, and a few colleagues inadvertently fell overboard, no one showed the slightest hesitation; instead, they met these mishaps with laughter. Upon returning to shore, they quickly regrouped—their fighting spirit undiminished—remaining fully energized and completely committed to the activity! The Great Crayfish Challenge: Teams navigate the lake in kayaks, putting their keen eyesight and speed to the test as they compete to catch the greatest number of crayfish—a contest brimming with surprises and fun! Canoe & Kayak Round-Trip Sprint: Each team fields two vessels, with the entire crew working in perfect unison to cut through the waves. Amidst the splashing spray, they challenge the record for the fastest round-trip time—a true showcase of both speed and passion. The entire event was filled with joy and laughter, and before anyone knew it, it had turned into a lively water fight party; with water splashing everywhere and laughter ringing out continuously, everyone had a thoroughly enjoyable and happy time. As the event drew to a close, the various groups gathered in circles to debrief. Unity, vitality, positivity, perseverance, giving one's all, embracing challenges, fulfilling one's role—these resonant keywords represent not only the takeaways from the day but, more importantly, the very essence of the team. We understand that a truly great team is on...

  • Industry Conference | Jointly Building a New Defense Line for Power Safety: Showcasing at the 2026 Petrochemical and Chemical Digital & Intelligent O&M Summit
    25/ March 2026
    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...
