The cores

* Stacking-type Core:
- Cores are made of cold-rolled, grain-oriented magnetic steel sheets of the highest quality. The sheets are cut accurately and stably by an automatic cut-to-length machine, driven by computer. The cutting angle is 450. Sheets are staggered on legs and yokes by step-lap technology. These factors reduce the values of no-load losses and no-load currents as well as of the noise and increase the mechanical solidity.

* Wound Core:

 

 

Cores of single-phase transformers and small three-phare transformers are produced with wound core technology. They are automatically cut and wound by automatic machine. The core with their step-lap joints are annealed to form shapes and reduce no-load losses.
