ZGS Series New Energy Combined Transformer for Photovoltaic and Wind Power Generation

With the rapid development of clean energy worldwide, photovoltaic and wind power generation systems require reliable and compact power distribution equipment. The ZGS series new energy combined transformer is a pad-mounted transformer specifically designed for renewable energy applications. It integrates the transformer body, oil-immersed load switch, oil-immersed fuse, high-voltage switchgear, and low-voltage power distribution equipment into a single compact unit.

The high-voltage chamber, low-voltage chamber, and transformer are arranged in a triangular structure, significantly reducing installation space while improving operational efficiency. The integrated design supports various configuration requirements including user energy metering, reactive power compensation, and low-voltage shunt distribution.

This combined transformer is suitable for terminal power supply systems of 35kV and below, with a capacity range from 500kVA to 5000kVA. The enclosure protection level can reach IP54 or higher, making it ideal for photovoltaic power plants and wind farms located on land, offshore platforms, and marine environments.
