1. Necessity for Oil Filter Unit

Currently, the importance of electric transformers is being more recognized in proportion with the increased demand for electricity.  However, frequent failures of the OLTC of transformers have caused unstable operation and short life span, incurring enormous damage.

With Chong-Ho  OLTC oil filter units, the organic acids, micro metallic powder, sludge, carbon, bubbles and moisture adversely affecting the major components in the OLTC are totally removed.  This in turn prevents waste of time and manpower by extending the regular OLTC inspection cycles and minimizes serious accidents that might be caused from insufficient inspection. The oil filter units also prevents rapid contamination of the inside the OLTC and mechanically and electrically prolongs the life of parts.  These oil filter units are therefore essential for the protection of expensive equipment.

2. Product features

Chong-Ho has succeeded in developing oil filter units that are far more advanced in terms of performance than those of the U.S., Japan, Europe and other advanced countries.  Chong-Ho superior performance has been proved in the nation, providing excellent quality, which is now causing all existing filters mounted on traditional electric transformers to be replaced by Chong-Ho  oil filter units.

① Low-noise, low-vibration and high flow are provided.

② Bubble-free, high-performance and extra-precision filters are used.

③ Use of oil heaters improves filtration performance and enables stable operation even during winter season.

④ Organic acids, micro metallic powder, sludge, carbon, bubbles and moisture are totally removed.

⑤ The application of permanent magnets removes even micro metallic powder contained in sludge.
