Transformer Accessories

Our in-depth process knowledge as well as modern production facilities allow us to successfully meet the demands of mitred transformer amination. The technical expertise of our team allows us to manufacture these for a wide range of transformers ranging from 5 KVA to 000KVA 'V' nothing and multi-holing as per customer requirements. We manufacture transformer core laminations for power and distribution ransformers from CRGO electrical steel in Grades M3(0.23), M4(0.27), M5(0.30), M6(0.35), MOH, ZDKH, ZDMH, TCH-0, TCH-1 as per the Customer's Specifications, rades and Drawings. Transformer lamination can be availed in various designs. Some of them are as follows: V-Notches, 45° Mitred esignRectangular design, Single or Multiple holes, Step lap design with vertical or horizontal step lap and Built up transformer core assembly.

Toroidal round cores offered by us find usage in low tension and high tension transformers and are wound from cold rolled grain oriented (CRGO) silicon steel strips ranging from 10mm to 100mm single slit and we offer core sizes from 15mm ID to 1000mm OD.To provide optimum performance.these toroidal cores are wound by automatic core winding machine and are annealed in high vacuum furnace under protection of nitrogen atmosphere or in continuous tunnel furnace, which results in features like compact volume, light, low magnetic leakage and hum & high efficiency. In CRGO grades required by customer, duly wound and annealed in inert atmosphere.Guaranteed No load current (AT /Cm) as per B-H Curve of particular grade In house testing facilities and 100% testing done on all Toroidal Cores at flux densities specified by customers. Annealing in controlled Nitrogen atmosphere for 18 to 24 hours (at 800° C) Testing for electrical values and issue of test certificates Painting or impregnation (if required).

Small magnetic hysterisis at higher induction, smaller apparent power, high permeability, low weight and small space volume and quick assembly-decreased labour cost. While ordering specify windows, stack and width of the strip in mm Material used in these cores are prime CRGO electrical steel in grades. M3, M4, M5, MOH, TCH-0, TCH-1, Z DKH. as per customers requirement while ordering specify the inside and outside diameter and strip width in mm.
