-CORE
The core is manufactured from cold-rolled grain oriented, (CRGO) silicon steel. The steel sheets are cut into required dimensions on automated machines thereby ensuring reduced air gap, low exciting current and low noise. Each lamination is insulated from each other to ensure a long trouble-free lifetime of the core. Using 45° stepping all leaning lamination way to laminate. So the no-load current are reduced efficiently.
1. Low loss, low noise, low partial discharge.
2. Strong anti-short circuit capability and high anti-lightning impact level.1. KEMA Test Report for Oil immersed Transformer
