Many manufacturers fail energy efficiency tests and lose bids. The root cause is often substandard CRGO cutting. If the slitting burr size exceeds 0.02mm, short circuits between laminations occur, causing core loss to jump by up to 15%.
To maximize magnetic flux, we utilize 45-degree fully oblique step-lap joints and 23Z110/27Z120 high-permeability silicon steel. This strictly limits no-load loss to ≤ 0.85 W/kg depending on the specific design. This rigorous parameter control is exactly why TBEA relies on our transformer cores, and it has successfully eliminated localized overheating issues in our recent Vietnam project deployments.
Question: What is the maximum no-load loss tolerance for your current 1250kVA or 2500kVA design? Let’s check the core data.
