RASQUINHA Transcore Electricals pvt Ltd . Rabale, Navi Mumbai, Maharashtra

transformer stampings The technical expertise of our team allows us to manufacture these for a wide range of transformers ranging from 5 KVA to 5000 KVA 'V' nothing and multi-holing as per customer requirements.

Random tests are conducted on sample of the CRGOCRNGO Raw Material. The CRGOCRNGO Lamination are packed on the wooden pallets and covered by the water proof cloth duly strapped in order to avoid damage to the core edges. Lamination for measurement of losses, insulation resistance, bend test, burr level.

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.

The silted coil are sheared in the treadle shearing machine at an angle of 45 degrees & in case of mitered core and 90 degrees in case of rectangular core. Utmost care is taken in grinding of the blades at specific interval of time in order to minimize the burr level not exceeding more than 10 micron.

The CRGO steel is received in the form of coil and can be silted in the minimum width of 10 mm and multiples of 5 mm. The cutters are frequently grinded to control the burr level.

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) .
