Transformer core lamination for Power & Distribution transformers is manufactured from various grades of Cold Rolled Grain Oriented ( CRGO ) steel. Lamination in various shapes & sizes are slit and cut to required accurate geometrical shapes with 90° & 45° cutting systems. The manufacturing of Cold Rolled Grain Oriented CRGO Quality Lamination involves a high degree precision engineering.

Transformer lamination can be of various sizes for single or three-phase transformers, made with overlap joints or step lap joints (Cross/Longitudinal). They are cut, punched and V-notched in order to fit in a particular transformer by CNC - cut to length line. Cutting, Punching and Notching of different shapes of sheets are possible in width up to 1000 mm and length up to 5500 mm. VSPL, with its integrated software to convert conventional design to Step lap design, insists transformer manufacturers to opt for Step lap design. Step lap core design enables easier path for flux to travel at the joints and therefore reducing No Load Losses of transformer core by 5 to 8%. VSPL team also assists in core assembly if required.

In addition to the cutting of the CRGO lamination, VSPL offers built core, assembled core (Overlap/Steplap joints).

Advantages CRGO Cold Rolled Grain Oriented steel product

• At VSPL, as we have full installed capacity and expertise for processing CRGO lamination, it has become possible for us to respond to the clients' orders with more speed and integrity. With adequacy of the inventory and supporting staff, the processing cycle has been cut short and thus, customers get the output faster.
• Because of the efficiency and integrity in production, VSPL has earned ISO 9001 Certification which is significant because very few companies in Lamination industry have got the certification which speaks for itself.
• The aspect of materials handling has been dealt with specific involvement as both the raw materials and finished products are highly sensitive.

Lamination Quality Check

Lamination quality control checks are carried out frequently right through the starting of manufacturing process on machine to the dispatch. All the records are maintained separately for each drawing so the tracking of particular job can easily be available on our finger tips. As a final step of process, delivery inspector conducts the required inspections of CRGO lamination and releases it for the dispatch
