Anhui Jinli has officially become a member of the Anhui Fusion Industry Association

On July 30, 2026, the Second Member Representative Conference of the First Session of the Anhui Fusion Industry Association was held in Hefei; Anhui Jinli Electric was awarded a membership plaque, officially joining the Anhui fusion industry ecosystem. Anhui Province stands as a national hub for innovation in the field of controlled nuclear fusion, boasting a robust foundation in scientific research and a well-developed ecosystem for industrial growth. The Anhui Fusion Industry Alliance (AFIA) brings together research institutes, key enterprises, and supply chain partners to create an industry platform that facilitates resource sharing, collaborative technology development, and the commercialization of research findings. The Alliance is dedicated to bridging the gap between cutting-edge technology and industrial application, optimizing the full fusion energy industry chain, and helping Anhui establish itself as a national leader in fusion innovation and industrial development. As massive, high-end scientific research facilities, controllable nuclear fusion devices feature complex system architectures and are subject to stringent standards regarding power supply stability, DC electrical safety, and protection against lightning and transient surges. Any overvoltage or lightning-induced fault in the electrical system can compromise the device's stable operation; consequently, electrical safety protection is an indispensable and critical supporting component of fusion engineering. Anhui Jinli has long specialized in the field of electrical safety and protection. As a member of various national technical committees for standardization—including those focused on surge arresters and lightning protection—the company serves sectors such as electric power, new energy, and rail transit, while accumulating extensive experience in customizing comprehensive lightning and overvoltage protection solutions for complex operating environments. Joining the association marks a new opportunity for the company's development.

Anhui Jinli's Smart Lightning Protection System Implemented at a Xinjiang Chemical Plant's 110kV Substation
Traditional lightning protection at chemical plant substations faces challenges such as the difficulty of predicting lightning strike risks, hidden corrosion in grounding grids, a lack of early warnings for lightning arrester degradation, hazards associated with manual high-altitude inspections, and the inability to retain O&M data. Leveraging IoT technology, LoRa wireless transmission, and a digital monitoring platform, Anhui Jinli Electric has developed a comprehensive smart lightning protection solution tailored for high-risk operating environments. This solution has been implemented at a 110kV substation of a chemical enterprise in Xinjiang, enabling 24-hour intelligent, proactive management and control of lightning protection equipment. 1. Focusing on two critical lightning protection points—substation grounding down-conductors and main incoming line surge arresters—Jinli Electric employs a light weight deployment solution featuring multiple terminals and wireless networking, balancing ease of installation with comprehensive monitoring capabilities. 1. Grounding resistance monitoring terminal: Powered by an explosion-proof lithium battery, eliminating the need for wiring or excavation; ensures stable outdoor operation across a wide temperature range and significantly shortens the retrofit schedule. 2. Surge arrester online monitoring terminal: Real-time acquisition of total current, resistive current, temperature, and lightning strike counts; enables early detection of insulation aging and moisture-related faults, preventing damage to main transformers caused by lightning strikes. 3. Wireless transmission + visualization platform: Field devices transmit data via long-range LoRa wireless technology, with an explosion-proof aggregation unit collecting and uploading data to a central control server. Includes a web-based (B/S) visualization monitoring platform supporting real-time parameter viewing, historical trend logging, pop-up fault alarms, and tiered access control. 2. Three Core Product Advantages 1. Explosion-proof and Corrosion-resistant: Complies with national standards for the petrochemical and hazardous chemical industries (e.g., GB50650, GB3836); suitable for facilities involving combustible dust, corrosive environments, and extreme temperatures. 2. Efficient and Cost-effective Retrofitting: Wireless terminals significantly reduce cabling and civil engineering work; eliminates the need for prolonged power outages during upgrades, thereby lowering labor and material costs. 3. Unattended O&M: Provides continuous 24/7 monitoring, replacing manual inspections at heights; delivers precise fault alerts, reducing the resources required for operations and maintenance. 3. Closed-Loop Digital Lightning Protection Management Moving away from the reactive model of emergency repairs following lightning damage, this approach establishes a comprehensive digital system—featuring front-end sensing, wireless transmission, central...
