10kv, 35kv Three Phase on Load Tap Changer Transformer

Posted by zjybelectric on May 7th, 2017

1. Brief Description
SZ11 series on-load-tap-changing oil-immersed transformer is an upgraded product developed based on S11 series oil-immersed transformer. The voltage fluctuation and load change of power grid lead to fluctuation of output voltage of transformer during the running. If the voltage is too high or too low, the electric equipment will fail to work normally and even be burnt, and the insulation and efficiency of the transformer will be influenced. To ensure the variation of the output voltage within a reasonable range, voltage regulation is necessary. The product may operate the on-load tap changer manually or automatically to regulate the voltage when it is loaded, or realize remote voltage control through a controller.
