As the “major arteries” for interregional power transmission, transmission lines—due to their extensive coverage and considerable length—are constantly exposed to external threats such as unauthorized operations by construction machinery. At present, incidents of circuit tripping and tower collapses caused by large equipment like cranes and excavators striking conductors have become increasingly frequent, making them the primary risk to the safe operation of the power grid.
Technology-Driven Safety: Millimeter-Wave Radar Builds a Collision-Prevention “Shield” for Bridges
Between 2024 and 2026, 70% of China’s key high-grade inland waterways will undergo digital upgrading and transformation, with intelligent sensing devices such as millimeter-wave radar becoming an indispensable component of bridge safety monitoring.
3D Millimeter Wave Radar Helps State Grid Prevent External Damage in Transmission Corridors
External damage incidents to transmission lines have become a major threat to the reliability and safety of the power grid.There is an urgent need for technological innovations in detection capabilities, application strategies, and management models to enhance the precision, timeliness, and effectiveness of monitoring construction machinery hazards. This will fundamentally eliminate potential risks and ensure the safe operation of transmission lines.
Successful Application Case of Millimeter Wave Radar in Lock Gate Systems
Common anti-entrapment and traffic efficiency solutions: visual cameras, infrared beams, LiDAR, etc. Considering performance, reliability, and cost, MMW radar + vision offers the best cost-efficiency. 70% reduction in gate collisions/entrapments, saving >8 million CNY in repairs. 25% higher traffic efficiency: Average transit time shortened from 40 to 30 minutes. 50% fewer manual inspections, cutting O&M costs by 20%.
