The choice of materials for the main body, roof, and walls of a steel structure substation significantly affects its strength, longevity, and performance.
Weather resistance
Weather resistance is a pivotal feature of steel structure substations. The thin layer of zinc coating on galvanized steel protects the structure from rust and corrosion caused by rain, moisture, and even snow. This makes it ideal for operation in severe climates and exposed environments. Furthermore, contemporary coatings, such as polymer-based or weathering steel, enhance even more the resistance of the structure to the harsh elements.
Corrosion resistance
Corrosion is a critical durability concern for steel structures. Steel is treated with galvanization or other anti-corrosive coatings to ensure its durability. Advanced polymer coatings and sacrificial anodes are sometimes used to enhance corrosion protection. These treatments ensure that even after extended use, the structure maintains its strength and ability to support heavy equipment.
Steel of high strength
The primary material used to construct substations is high-strength steel. Steel has a high tensile strength, which makes it capable of supporting the heavy electrical appliances. Steel frames are much lighter than concrete, making them simpler to install. This, in turn, reduces the time and costs involved in construction.
Earthquake and impact resistance
Steel structure substations are primarily designed to withstand seismic activities and other impacts. Steel's inherent malleability enables it to absorb and dissipate energy during earthquakes or sudden impacts. This property makes them ide for use in high-seismic zones. They are also fitted with dampers and base isolators to enhance the overall durability of the structure.
Hybrid construction materials for enhancement of durability
Hybrid steel structure substations incorporate both steel and concrete elements to capitalize on the benefits of each material. While the steel frames provide flexibility and strength, the concrete foundations offer excellent stability and rigidity. This combination improves the substation's durability, enabling it to withstand higher loads, seismic activities, and adverse weather conditions.
Urban and rural areas power distribution
Steel structure substations efficiently manage electrical distribution in both urban and rural settings. In densely populated city areas, the compact design allows space-saving installations.
