220kV and Below Prefabricated Smart Electrical Series

Advanced Manufacturing Machine

• Corrosion Resistance: The steel components are galvanized and coated with epoxy primer to ensure a corrosion-free lifespan of 40 years, with an additional anti-corrosion coating for harsh environments (e.g., coastal regions).

• Fire Resistance & Insulation: Double-layer steel plate with polyurethane and rock wool insulation (thermal conductivity ≤0.05 W/(m·℃)), ensuring fire resistance (fire rating: Class II, fire resistance limit: 3 hours).

• Steel Structure: The substation features a welded steel frame with H-section steel for the main structure and galvanized steel for the base, providing excellent impact resistance and structural rigidity.

• Electromagnetic Shielding: Uses full-metal housing to reduce electromagnetic interference (EMI).

• Sealing & Protection: Sealed with silicon rubber or EPDM gaskets, ensuring high airtightness (IP54). Equipped with anti-dust, anti-moisture, and anti-condensation features.

• Door & Window Design: Doors feature a double-layer steel plate with thermal insulation and fireproof materials, ensuring excellent insulation properties.

• Seismic & Wind Resistance: Rated to withstand seismic forces of up to level 8 and designed to endure strong winds.

• Integrated Systems: Pre-configured with power distribution, HVAC, fire detection, security systems, and intelligent monitoring (such as SF₆/O₂ sensors, temperature monitoring, etc.).
