Power Distribution Transformers
Our Power Distribution Transformers are a critical component for
stepping up and stepping down voltage within the transmission network,
making them ideal for renewable solar applications and receiving
substations.

Key Features:
Robust Construction: |
Transformer tanks are designed for safe lifting and transportation and are effectively sealed against oil leakage. |
High Dielectric Insulation: |
Features the highest dielectric insulation property to withstand lightning Designed for better aesthetics and enhanced safety with a tamper-proof construction. |
Optimised for Efficiency: |
Includes step-lap designed CRGO laminations for lower losses and excitation current. |
Enhanced Coil Quality: |
Coils undergo pre-heating under vacuum to achieve the desired compression height and utilise Perma wood clamping rings for uniform compression of primary & secondary winding. |
Thermal Management: |
Adequate ducts between layers, coils, and discs ensure maximum oil flow and reduced hot spot temperature. |
