Small Power Transformers

Medium voltage power transmission and distribution

Optimum power distribution for medium voltage ranges up to 100 MVA and beyond

Small power transformers (also known as substation transformers) are critical components in the electric grid—responsible for stepping up or down voltage levels to ensure the safe, efficient transmission of power. They are used across a wide variety of industry applications from renewable energy to transportation, data centers and much more.

Our small power transformers are designed to handle low to medium voltage ranges and power levels up to 100 MVA and beyond, with the capacity to operate under harsh industrial conditions and the flexibility to adapt to specific technical requirements. Our transformers provide smooth operation of industrial equipment, contributing to optimized performance and reduced operational costs. The compact size allows for easy integration into various systems and our reputation for robust construction ensures durability and minimal maintenance.
