Corrugated Transformer
Corrugated Transformers are oil-filled distribution or small power transformers featuring corrugated tank walls that serve as integral cooling surfaces. Designed for compactness and improved thermal efficiency, these transformers are widely used in residential, commercial, and utility networks. With ratings up to 6 MVA and voltage class up to 33 kV, they offer reliable performance with low maintenance.
Assured Features
- Highest dielectric insulation property to withstand Lightening Impulse.
- Mechanical design to withstand short circuit forces arising during faults.
- Optimum oven heating under vacuum as to achieve desired compression height and maximum insulation resistance (IR) to windings.
- Adequate ducts between layers, coils, discs for maximum oil flow and reduced hot spot temperature.
- Step-lap designed CRGO laminations for lower losses and excitation current.
- Pre compressed Insulation material for minimal moisture absorption.
