Eco Transformer

Transformers replace mineral oil produced from crude oil with flame retardant/environmentally friendly synthetic ester oil or natural ester oil. The ignition point is higher than 300°C, and the risk of fire is low, and the high biodegradation rate reduces the risk of environmental pollution in case of insulating oil leakage.
DPRS, TPRS Transformer

As the demand for measures to prevent explosions and fires in hydroelectric power plants and densely populated areas increases due to the tightening of environmental regulations, we have developed Explosion Proof design. A new and economic technology called Dynamic Resistanct System(DPRS) is taking the lead in responding to environmental regulations and is applied to DPRS delivered to the electric utilities in the United States.
High-Efficiency/Low Noise Transformer

Installed in urban areas with high sensitity to noise, this transformer focuses on minimizing the size and weight to increase the efficiency in transportation, installation and operation. In addition, carbon reduction can be realized with lower power loss compared to existing ones.
Gas Insulated Transformer

SF₆ gas transformers are suitable for applications that are vulnerable to fire, have limited space, and have installation load limitations, such as underground substations near urban centers. We have domestic and overseas performances based on design technology for water/air cooling.
SVC Transformer

SVC which controls the power through the electric system to maintain the system voltage, and is connected to the system must be designed and manufactured in consideration of insulation and the harmonics of the mangetic flux.
Phase Shift Transformer

Phase shifting transformers are mainly installed between countries with power exchange to control the power flow considering the current power supply and demand. Depending on the voltage, capacity, and system requirements, it can be configured as Dual Core or SIngle Core design and customized to customer needs.
HVDC Converter Transformer

It connects HVDC (High Voltage Direct Current Transmission) to existing grids.
Trackside Transformer

It is used as a scott connection method for feeding electric railways.
Furnace Transformer

It is a transformer used in blast furnace and prevent it from being overheated due to high current.
Marine Transformer

It is a transformer used for offshore substations and platforms and is equipped with vibration reduction and flame-retardant functions, enabling stable power supply.
Mobile Transformer

Mobile transformers are installed in areas in urgent need of electricity. Based on our performances, compact design is available with customer requirements satisfied.
