Transformer Substations

Craftsmanship combined with decades of experience and innovative technology


Prefab transformer substations are our primary expertise. Alfen Elkamo built its very first transformer substation over 20 years ago, and we have been working hard to equip them with the latest technological developments and innovative solutions ever since. Alfen transformer substations are tailored solutions, ensuring they provide matching answers to every situation and user profile. We take pride in the fact that we have delivered thousands of stations to grid operators, industrial corporations and the horticultural industry.
