This Hua-style prefabricated substation handles photovoltaic boost duty, converting 35 kV down to 400 V. A switchgear/distribution compartment works alongside an externally mounted oil-immersed booster transformer, complete with radiator-fin cooling and an oil conservator, to deliver compact step-up capability for new-energy sites.
Photovoltaic power stations, energy-storage step-up applications, and new-energy collection and grid-connection projects.
Enclosure colour, capacity, voltage ratio, transformer type, and switchgear configuration are available on request.
Every unit is manufactured to order against the specification confirmed by the customer. Please provide the required capacity, voltage ratio, and application when enquiring.
The product images shown are illustrative marketing renders; the delivered unit is manufactured to the specification confirmed at order.
