Step-lap cores, oxygen-free copper windings and vacuum oil filling give our transformers low losses, low noise and exceptional thermal life. Every unit is routine-tested per IEC 60076 before it leaves the factory.
Cores are cut on CNC lines and windings wound on automated machines with vacuum drying and oil filling. Every unit passes full routine tests per IEC 60076 in our CNAS-accredited laboratory; type tests are witnessed at KEMA / CESI.
Utility distribution networks, commercial buildings, industrial plants, renewable energy plants, mining and infrastructure — from pole-top units to 240 MVA power transformers.
