Steel Lamination

We offer customers Cold Rolled Grain Oriented Steel (CRGO) based electrical transformer lamination products. With basic basic material used for manufacturing both laminations & wound cores being cold rolled grain oriented steel (CRGO) steel, which are imported from reputed overseas mills in various grades of different permeability, we ensure optimum functionality standards of equipment these are used in.

 

Features:

• Basically, there are many types of CRGO steel including M-3, M-4, M-5 and M-6 grade and hi-b material
• These basic material are imported in forms of coils having standard width of 750/1100 mm or in form of slits
• CRGO material has least figure of maximum core loss in rolling directions (With increased shearing angle to rolling direction, core loss at any particular flux density goes up & becomes generally highest in transverse direction due to which it is possible to use CRGO in static electrical machines including all types of power transformers, distribution transformers, reactors, audio transformers and others)
• Manufacturing mills of CRGO steel guarantee core loss figure at flux density of 1. 5 tesla for conventional grain oriented steel at 1. 7 tesla in cases of hi-b and hi-b-ls steel
• The grades of material popularly used are m-3, m-4, m-5 and m-6
• We also use, for special requirements of the customers, hi-b material designated as moh, tran-cor, h, zh, zdkh, zdmh
