Power covers are specialized supporting components used in electrical engineering projects. They are primarily made of concrete, with some types incorporating steel reinforcement cages. Manufactured to national standard specifications, they are suitable for State Grid cable trenches, utility manholes (electricity wells), power distribution boxes, and similar facilities. They exhibit compressive strength, wear resistance, corrosion resistance, weather resistance, and anti-slip stability. They effectively protect underground power lines, prevent external damage and rainwater leakage, while also allowing easy access for line inspection and repair. These products come in a full range of sizes, are easy to install, meet the standardized construction requirements of State Grid power engineering projects, and are widely used in urban and rural power grids, municipal power supporting facilities, and other scenarios.
