SZ11 35KV Class Three Phase Oil-Immersed Distribution Transformer

The SZ11 35KV on-load tap-changing power transformer is a specialized type of transformer designed for use in high-voltage power distribution networks. It has several distinct features that make it suitable for a range of applications, particularly where voltage regulation under load conditions is required.

S11, SZ11 series of oi-immersed power transformers are more advanced in design.The material , the structure and process has been improved greatly.Having beautiful appearance, reliable operation, low loss and low noise.the transformers reach the advanced level compared with similar foreign products.

The SZ11 series can adjust voltagemanually, electrically or automatically in a side with the help of OLTC on the voltage regulating range , so as to ensure the stability of the output voltage.
