Design Concept of ourTransformer
Ourtransformers are designed and manufactured through verification from the design stage using design program, electromagnetic field analysis program, and structural analysis programDielectric Strength Ourtransformers 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.Thermal Capability Heat generated from coils which form electric circuit inside the transformer and heat from iron cores form magnetic circuit and is transmitted to insulating oil. Heat transmitted to insulating oil radiates to the air through the cooler. Cooling effect is very important as it is directly linked to insulation life and the capacity of the transformer.Our transformers lay emphasis on improving cooling performance and regulating temperature of the hottest spots by using an effective cooling system.Mechanical Strength Reliability of transformers manufactured byus is excellent because of winding and tank design which distributes mechanical force evenly in case of short circuit and supports short-circuit strength effectively.
Manufacture Procedure
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.
