Equipments and Production

Core Production:

Transformer magnetic cores are produced of high quality silicon grain oriented electric steel with low and extra low specific loss including steel with laser treatment Electric steel length cutting is carried out on George automatic slitting lines.

Core-plates are cut on GEORG (Germany) high-precision automatic CNC cross-cutting lines equipped with hard-alloy tools and V-dies. The sector of automatic line of cross cut electro steel cutting Georg with Pressing and packing of finished E-core is responsible for automated cutting and assembling of transformers' core. It is automatic core slitting and cutting machine and its core assembly lifting platform capacity 150 MT.

Automatic core Slitting machine with de-burring attachment for burr-free laminations– from Georg GmbH, Germany Automatic core cutting machine with v-notch cutting, hole piercing, step-lap joints and stacking facilities - from Georg GmbH, Germany with dedicated 10 MT EOT Crane.


Facilities including Brockhaus test system from Germany for testing magnetic characteristics and insulation resistance of CRGO steel sheets.
