Advanced materials have become a cornerstone of high-performance grounding systems. Copper-clad steel and graphite-based grounding electrodes dominate in corrosive environments such as coastal areas and chemical plants across Europe and North America, accounting for over 60% of installations in these regions. These materials combine the mechanical strength of steel (tensile strength ≥600N/mm) with the superior conductivity of copper (resistivity ≤0.1Ω·mm), offering a 40% cost reduction compared to pure copper systems while extending service life to over 50 years. Conductive polymer grounding strips, capable of withstanding 5,000 bending cycles without performance degradation, are increasingly adopted in wind farms and data centers where installation space is limited.
Nanomodified ZnO varistors have revolutionized SPD technology, enhancing response speed and service life to support the proliferation of intelligent SPDs. These materials enable SPDs to operate reliably in extreme temperature ranges, reducing failure rates to 0.18‰ per year in harsh environments.
2.2 Intelligent Transformation: IoT and AI Empower Proactive Protection
Internet of Things (IoT) integration has become a key trend, with real-time monitoring systems collecting data on grounding resistance, leakage current, and temperature for remote alerting and predictive maintenance. The global lightning IoT market is growing at a CAGR of 12.5%, driven by demand from renewable energy and data center sectors. AI-powered prediction models, combining lightning location network data with meteorological forecasts, enable risk classification and dynamic optimization of protection strategies, significantly improving the effectiveness of LPG systems.
Modular and hot-swappable SPDs have emerged as essential solutions for data centers and 5G edge nodes, allowing maintenance without system shutdowns. These compact devices, some achieving three-level protection in a 50mm³ space, support the 24/7 operational requirements of digital infrastructure.
