Substation Steel Structure Support

Customized according to drawings
Substation steel supports are specialized steel structures used to centrally support and secure various electrical equipment (such as circuit breakers, disconnectors, current/voltage transformers, lightning arresters, and coupling capacitors), busbars (including flexible and tubular busbars), and disconnector operating mechanism boxes within the substation. Their core function is to provide safe, stable, and rigid support that meets electrical insulation distance requirements for live conductors throughout the station. This structural system primarily consists of equipment supports, busbar beams, center columns, and various embedded components for equipment foundations. It is typically constructed from hot-rolled or cold-formed steel (such as H-beams, square steel tubes, and channel steel) and assembled using high-strength bolts or welding. The primary steel is typically graded Q235B or Q355B and treated with hot-dip galvanizing or heavy-duty anti-corrosion coatings to ensure long-term weather and corrosion resistance. Its design needs to comprehensively consider complex working conditions such as static loads on the equipment, dynamic operating forces (such as the opening and closing torque of the disconnector), wind loads, snow loads and earthquake effects, and strictly follow the "Code for Loads on Building Structures" (GB 50009) and the "Design Standard for Steel Structures" (GB 50017) to perform strength, stiffness and stability calculations. The ultimate goal is to ensure the absolute position accuracy and structural safety of all electrical equipment in the substation during operation. It is a key structure for achieving compact, modular and reliable operation of substations.
