This 630kVA pad mounted transformer (ZGS American compact substation) is an integrated outdoor distribution equipment widely adopted for urban underground power grid. It combines high voltage switch compartment, protection fuses, hermetic oil immersed transformer and low voltage distribution panel within one compact enclosure.Available in radial feed / loop feed, dead-front and live-front configurations to meet North American and global distribution standards. Mainly applied in residential subdivisions, commercial plazas, municipal roads, parks and industrial zones. Factory pre-assembled design minimizes civil work and onsite installation workload.
