Chinese-style (Hybrid) Box-type Substation

Combining the best of European and American designs, the Chinese-style substation integrates HV switchgear, LV distribution panel and oil-immersed transformer in a weatherproof enclosure. The transformer is mounted outside the switchgear compartments for efficient cooling. Optimized for PV and wind power, it supports large capacities and meets the latest energy efficiency standards.

Four-part structure — HV switchgear, LV panel, transformer and housing, factory-assembled
External transformer — radiators exposed for natural cooling; forced ventilation available
Five-prevention protection — complete control, protection, live-display and lighting systems
New-energy ready — up to 12000 kVA
