The ZGS13 series wind and solar power dedicated step-up transformer is an integrated compact substation-type transformer unit designed for renewable energy generation systems.

It combines the following components into one compact structure:

• Transformer core and winding
• Switchgear
• Fuses
• Tap changer
• Auxiliary equipment

The unit uses transformer insulating oil as both insulation and cooling medium, ensuring high efficiency and stable operation.

It is designed to convert generated power from:
👉 0.69kV (0.27–1.14kV)
into
👉 10kV or 35kV medium voltage level

for grid transmission via underground cables or overhead lines.
