Product Description

 

Product Description

Overview

S11 series is advanced designed to upgrade the former transformers in performance.

It has compact structure which requires a much smaller space to install. Its noise has been lowed down and capacity of overloading has been enhanced.

Comparing to S9 series, S11 series product decreased the loss of No-load by 30%. And current of no-load declined to 45-80%.

We have S11,S13, S20, S22 Serie transformers



Features

Low loss and small current in no-load condition. Low noise.
No oil conservator, space-saving for installation
New Oil Guage design makes sure it runs safely
Corrugated oil tank, good cooling performance and flexible in shaping change while its heating.
Cost-save, Long lasting service, Easy to maintain
