We are renowned in the market for manufacturing, supplying, and exporting of premium quality Transformer Coils . Our Transformer Coils are assembled under the Slitting Process, which is the first and foremost manufacturing process in order to obtain any type of cut lamination. Indeed, it is the heart of the whole manufacturing process and to ensure it continuous beats, it should be tuned with fine accuracy and high quality standard. Slitting process is the origin where quality standard starts, and subsequently it is maintained by the different types of cutting process. Quality of the material is always on top priority, and thus we stress more on slitting process for better quality in every single process. We have the facilities to cut strips from the entire range of CRGO coils used by the Electrical Steel Industry, with high permeability in thickness ranging from 0.18 to 0.35mm. We have set up essential quality check-points during slitting process to ensure that the burr level of material is well within the tolerance. The precise slitting process can undoubtedly slit the material without any generation of scrap. (I.e. slitting of a coil of 120 mm in two different 60 mm coils is promising task).

We are considered as one of the leading Manufacturers, Suppliers, and Exporters of Toroidal Core Transformer . Our Toroidal Transformer Core is fabricated under the guidance of experts to ensure its premium quality and dimensional accuracy. We conduct a special process with high degree of precision to manufacture Toroidal Transformer Core to meet the diverse needs of Reactors, Chokes and so on. Manufacturing process The manufacturing of strips wound cores is a specialized process, which requires a high degree of precision. These cores are manufactured from selected coils of crgo electrical steel to yield closely controlled electro-magnetic characteristics and dimensional accuracy. Cores are wound after slitting is done as per the required shape, on the core winding machine. The winding machine automatically stops when the pre-decided dimension is reached. The start and finish ends are firmly spot welded. After winding, the cores are stress-relief annealed to restore the magnetic properties. The cores are bonded where necessary, to provide increased firmness. All cores are spray painted or varnished (as required by customers) and are tested for magnetic properties. Testing Strip wound cores, unlike strip lamination, constitute a complete product and every core must meet the specified performance requirement. Consequently, quality control in the manufacturing of wound cores is vitally important at every stage of process. Dimensional tolerances The coils of crgo steel from which the cores are manufactured are carefully selected on the basis of tests carried in our laboratories to ensure that the correct grade of steel is used. Strict checks are made at every stage from winding to the final stage of spray painting & varnishing to ensure that the finished product is of a high quality. Moreover, each core is subject to inspection and electrical tests at BSP to make certain that our customers are provided with the specified performance requirement. Apart from being fully equipped to meet the exacting standards of testing required, BSP possesses the technical knowhow, the research facilities and the necessary raw-materials.
