Solar Application Transformers (Multi Winding)

What Are Solar Transformers ?

Transformers Are critical Components in solar energy production and distribution. Historically ,Transformers have "stepped-up or "stepped-down" energy from non reliable sources. There are different types of solar transformers including distribution ,substation , pad mounted and grounding .

All Solar Transformers have specialized that need impact costs. Normally these types of transformers are accommodated by device that measure heat related volume variations . Gas Cushion is used to compensate the volume variation due to heat. Normally the gas is nitrogen. this gas is thermally uncoupled from the dielectric liquid.

Solar Applications

On Utility Scale solar energy facilities , voltages are transformed after the inverter for delivery to the utility grod voltage. A Transformer on a solar power facilities is primarily used to step-up the voltage to deliver the renewable energy to the utility grid.

Our Solar Range Transformer range starts from 750 KVA - up to 6 MVA , Feeding to central inverters of 3 MVA Each , Both in 11 KV And 33 KV.

At Present We Are Manufacturing 2 MVA , 2.5 MVA And 3 MVA , 11KV and 33KV Feeding to Central Inverters.
