Excellent short-circuit resistance.

Satisfies the various load conditions required by customers.

Low-loss step lap laminated core.

Uses latest insulation material with high short-circuit strength to realize high thermal capacity.

Cold steel sheet is used for radiating pipe to ensure a sufficient cooling effect and aesthetic exterior.

Compact, light, and low-noise transformer with standard efficiency and noise level which can be easily installed even in a small indoor or outdoor area.

Radiating Structure

Manufactured with the thin, cold-rolled steel sheets containing a vertical oil path, where insulation oil can circulate; each radiating pipe is constructed of two cole-rolled steel sheets, which are parallel and have equal length.

The length of the radiating pipe is determined by the tank's height. It is divided into a separate or all-in-one type depending on the welding method used.

Customized design is available by combining the radiating sheet in a variety of ways; the radiator can be separated for transportation.

General Cast Resin Transformer

Self-extinguishing characteristics of epoxy significantly reduces the spread and effect of a fire and the possibility of explosion is nearly non- existent.

Easy transportation and installation with simple structure.

No toxic substance (oil or gas) discharged.

Adopts a higher class epoxy resin.

Epoxy Resin; uses H class epoxy resin, which is higher than the standard F class, as the main insulation material of the mold transformer to control thermal aging and extend the overall lifetime of the transformer by three-folds.

Winding structure: when the radial build (RB) of the high-pressure winding is large, the temperature difference between the center and the surface of the winding gets higher, then crack in the winding may cause a partial discharge. Therefore, when the RB is large, an air duct is inserted making the RB thinner, then the temperature difference between the center and the surface is reduced and cracking is prevented.

When the air duct is inserted, the electric field distribution of the high-pressure winding becomes stable and the withstanding voltage becomes more resilient against external surge.

Casting process quality management: By strengthening quality management and interim examination of the casting by batch is checked (*Testing is required for checking how high the temperature is required to be for transiting from the solid glass-like elasticity of the solid polymer to the flexible rubber-like elasticity as well as checking the chemical combination status of the epoxy resin and process stability.).

By adopting the latest analysis technique, the transformer can be operated under severe conditions.

Satisfies the customers by resolving various failures and anomalies, which may occur in operation on site, through technical analysis and visiting the site when customers request after-service.

Common and public facilities: Condominiums, hotels, studio apartments, shopping malls, hospitals, and other public facilities.

Manufacturing factories: Automobile factories, semiconductor factories, and chemical factories.

Special areas: Power plants(nucler, water, fire, wind, and tidal), airports, subways, container cranes, and tunnel excavation work.

High Efficiency Cast Resin Transformer

Improves the noise level by 8~11dB or more compared to the KS standard.

More advantageous to use special loads by securing harmonic characteristics.

Secures about 15% of continuous overload capability.

30% of electricity charge is saved per year, compared to the general cast resin transformers, thus reducing costs over the long run.
