Sarjani Industries has installed facility to manufacture oil filled power and distribution transformers up to 5000 kva, 3 phase, 11 kv/22kv/33kv with OLTC & OFTC. (ONAN)

Our in-depth process knowledge as well as modern production facilities allow us to successfully meet the demands of Mitred Transformer Lamination. The technical expertise of our team allows us to manufacture these for a wide range of transformers ranging from 25 KVA to 75 MVA 'V' nothing and multi-holding as per customer requirements   Specifications :   Available with 'V' Notching & Holing Facilities Distribution and Power Transformer LaminaƟons in upto 15 MVA. Step Lap Laminations with Tip Cutting(both horizontal & vertical step lap) to give reduced losses. Stress relief annealed laminaƟons to give lower losses and lower current values

Toroidal Coresand Toroidal Ring Cores  offered by us have find usage in mains transformers and are wound from cold rolled grain oriented (CRGO) silicon steel strips to provide optimum performance. These toroidal cores and ring cores are wound by automatic core winding machine and are annealed in high vacuum furnace under protection atmosphere or in continuous tunnel furnace, which results in features like compact volume, light, low magnetic leakage and hum & high efficiency. Specifications :   Sizes upto 1000 mm OD 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

Sarjani Industries are manufacturing Automatic Voltage Controller (AVC) between 30 KVA to 5000 KVA with Microprocessor Based Technology. The prime purpose of AVC is to maintain the breakdown of electrical appliances and equipments due to high and low voltage. Voltage deviation is a common incident. The input voltage is generally less during day time and prominent during night hours.

We offer clients high performance  Transformer Cores, core frames, oriented core frame  assemblies that find application in meeting the specific application demands of industrial and commercial transformers. These  Core Frame Assemblies  are also duly assembled and tested for no load losses with turns, which assure clients of their flawless and consistent performance. The rectangular strips we offer are available in different specifications / finishes as per their specific application requirements in transformers. Our process expertise also allow us to deliver these rectangular strips in special type of HI-B grade material in loose conditions or assembled to customers requirements. We have with us cutting-edge technical expertise to meet the specific manufacturing demands of core frame assemblies. These are offered for a wide range of transformers starting from 25 KVA to 5 MVA. Further, the high quality standards followed during the production stage also ensure optimum service life standards for core frame assemblies. Specifications :   Miltered Lamination core frame assemblies  upto 5 MVA with facilities to test no load losses off power analysis of our works.

We manufacture CRGO slit coils and CRNGO Slit Coils to customers specification from the required grade of materials. It is well known that handling and processing of Grain Oriented Electrical Steel (CRGO) can create undesirable stresses within the metal internal structure and at the cut edge. These stresses are a result of distortion of the crystal structure caused by the shearing process and result in increase of the hysteresis and decrease of permeability.
