10MVA Three Phase Substation Transformer Product Description

10MVA Three Phase Substation Transformer Oil Type Step Down 22.9KV To 4160V IEC60076 Standard

ZTELEC YUGUANG offers a complete line of liquidfilled distribution transformers that meet current applicble ANSI, IEEE, CSA, AS, DOE standards. With high voltages up to 44 kV and ratings up to 20 MVA.

The substation transformers designed by WINLEY Electric are based on IEC60076 standard. They absorb and utilize advanced domestic and foreign technologies to optimize the transformer core, coil, body, lead wire, oil tank and other components. They have the characteristics of low partial discharge, low loss, low noise, light weight and long service life.
