Extra High Voltage Transformer

Development of low loss, high efficiency extra high voltage transformer through endless research.

First Korean SME to Develop KEPCO 154kV Extra High Voltage Transformer and Acquire KERI Certificate
KOC Electric successfully developed KEPCO 154kV extra high voltage transformer for the first time as a Korean SME. After the acquisition of KERI certificate, the transformer is registered at KEPCO.
Based on KEPCO registration, we started to enter 154kV transformer private market in earnest and become an electric power total solution that supplies 154kV class electrical infrastructure system with the latest facilities.
By satisfying international technical stands such as IEC, ANSI, NEMA, BS, JIS, and JEC as well as domestic technical standards, we have secured the ability to design, manufacture, and test according to each country’s standards and become a global transformer manufacturer.

• Adopted Frequency Transition Device as 154kV Test Equipment for the First Time in Korea
• Implemented Auto-calculation & Auto-setting of Condenser Bank for the First Time in Korea
• Activated Minimum Value of Surrounding Noise
• Installed Vapor Phase Dry oven(VPD) with Kerosene Vacuum Drying Method
