Hua-Type Compact Prefabricated Substation up to 35 kV

The Hua-type compact prefabricated substation combines voltage transformation with protection and operating functions in a compact outdoor arrangement. It is intended for wind power, solar PV, energy storage and urban distribution applications where the layout must accommodate both electrical capacity and available site space.

The range supports several low-voltage options, allowing the transformer configuration to be matched to the connected equipment and the project’s collection or distribution scheme. Step-up or step-down service is determined by the application and the specified voltage ratio.

Condition monitoring, data acquisition and remote operation can be incorporated into the configuration. For coastal or exposed locations, enclosure protection, corrosion protection and environmental design limits should be specified against the actual installation conditions. These requirements should be reviewed alongside capacity and voltage selection.
