Business Areas


established in January 2000 and is a specialized company in the design
and engineering of "High Voltage Underground Transmission System".

It is a mature company that provides "Total Solution" for construction and operation of high voltage transmission field.

In February 2006, we established a company-affiliated research institute and conducted research on construction management. Since 2015, we have started to develop underground distribution accessories and have begun full-scale manufacturing. We are also engaged in research activities on materials, manufacturing, design, analysis and analysis related to the manufacturing of connection materials and parts for power equipment.


Organization and work

EPE's R & D center is developing the electric power equipment products that are suitable for the future trend with the goal of developing the world’s best product that is the goal of the CEO.
In recent years, in response to a change from a power grid network, which is a unidirectional power grid, to a micro grid grid, which is an interactive power grid, there is a need for products that meet the changing trends of environment
friendly, high performance, and compact devices.
In a changing environment, EPE R & D center is constantly researching on the development and manufacturing of power equipment and parts with the world's best competitiveness in order to meet the demands of our customers continuously.
Major research fields of EPE R & D center focus on MV / HV cable accessories, switchboards, lightning arresters. In addition, we are involved in design technologies such as insulation management, metal characteristics, productivity improvement, product analysis, and material analysis.
