A transmission steel pole, also known as a steel transmission tower, is a crucial infrastructure for electric power transmission. Constructed from high-strength steel, it features a robust framework to support overhead power lines, enabling long-distance electricity delivery. Its design ensures stability against harsh weather like wind, snow, and earthquakes. These poles vary in height and structure based on voltage levels and terrain, often with multiple cross-arms to hold conductors. Easy to install and maintain, they balance durability with cost-effectiveness, playing a vital role in global power grids to safely transmit electricity to homes and industries.
