1. The heat sink of the ZGS series new energy (wind/photovoltaic) combined transformer is exposed outside the box transformer, which is beneficial for transformer heat dissipation and meets the operating requirements of full load and overload.

2. Beautiful appearance, compact structure, small volume, flexible disassembly and assembly, convenient, fully sealed, high and low pressure components separated and placed in the box, only equivalent to 1/5 to 1/3 of the volume of similar box type transformers.

3. The box adopts a fully sealed design, unique anti‑corrosion design and special painting treatment, which can be widely used in various harsh environmental conditions, effectively ensuring the safe and reliable operation of electrical equipment and achieving maintenance‑free operation.

4. The high‑voltage load switch is installed in the transformer oil tank. The switch has a small volume, can be switched freely, and can safely and reliably break the load current. It is easy to use and has high power supply reliability.

5. Due to the small size and compact structure of the combined transformer, it integrates the transformer, low‑voltage equipment, metering and measurement into one, without the need for a distribution room. The incoming line is introduced from the cable trench and directly installed in the load center. The cable plug can be plugged and unplugged with power when necessary, making the connection convenient. Reduced the investment cost of the substation, resulting in less initial investment and lower installation costs.
