Reliable 6.6MVA Containerised Substation for Medium Voltage Power Distribution

The 6600kVA Containerised Substation is a fully integrated power distribution solution combining medium-voltage switchgear, a 6600kVA oil-immersed transformer, low-voltage distribution equipment, and intelligent monitoring systems within a robust IP54 container enclosure.

Designed in accordance with IEC 60076, the substation features a 20kV ±2×2.5% / 0.8kV-0.8kV transformer, ONAN cooling, Dy11-y11 vector group, and high-reliability protection devices. The factory-assembled design significantly reduces installation time, civil construction costs, and commissioning efforts.

Suitable for solar power plants, wind farms, industrial facilities, mining operations, utilities, and infrastructure projects, this compact substation delivers safe, efficient, and reliable power distribution in demanding environments.
