Our transformers are designed and manufactured through verification from the design stage using design program, electromagnetic field analysis program, and structural analysis program.
I. Dielectric Strength
Our transformers guarantee dielectric strength to withstand impulse voltage thanks to high-technology design which ensures low capacitance between winding and the ground and proper coordination of insulating material and solves creepage problem.
III. Mechanical Strength
Reliability of transformers manufactured by us is excellent because of winding and tank design which distributes mechanical force evenly in case of short circuit and supports short-circuit strength effectively.
01 Windings
Windings are composed of two parts, namely, a conductor and insulation material. For the conductor, we use high grade electrolytic copper or aluminium. Our Oil Immersed Transformers obtain high thermal capacity with the use of Epoxy coated Insuldur Kraft Paper, which has higher short time overload capacity than any other Kraft paper type.
02 Core
Core design is essential because it determines the transformer's efficiency and noise level. For high dimensional accuracy, the core cutting processing of us is controlled by a computerized system. By Step-Lap core stacking, Our Oil Immersed Transformers attain to optimal characteristics for each customer.
03 Winding Support System
Coils are sized and clamped by being pressed with a special hydraulic fixture after assembly with the core. With Axial and Radial direction, we reinforce the winding support system. This secure structure helps withstand harsh short circuit forces.
04 Radiator
The transformer will be furnished with panel or corrugated radiators assuring that the temperature rise of the windings or oil will not exceed their specified limit when the transformer continuously operates at the rated full load.
