In order to meet the various electrical requirements of the clients, we have been engaged in offering our clients an optimum quality EI Lamination Core. The offered core is manufactured using the finest quality metals and modern technology at our advanced production unit. This core is available in both small and big sizes and is used in transformer making. Apart from this, EI Lamination Core is tested on several parameters in order to eradicate all possible flaws of production.

We manufacture all kinds of E & I laminations as per customers specifications as well as Standard Types which are used widely in CRGO grades M4, M5 and M6 and CRNGO Grades M45, M47 or as per customers specified grade.

These type CRGO Transformer E & I Lamination are used in control transformer, Instrument Transformers and Iron core chokes, Ballast, And variety of electromagnetic application.

Our customer can avail from us a qualitative range of CRGO Sheet, which are fabricated from high grade of raw materials. This range is available with us in various dimensions, sizes and lengths. The product range offers utmost efficiency, easy installation and removal and trouble free operations to our clients.

We hold expertise in the manufacturing, retailing, supplying and exporting of the wide range of CRGO Sheets, which is widely used in telecommunications industry, steel industry, iron industry and power supplies companies.

We can provide CRGO mother coils and CRGO Slit Coils, also known as Metal Coils, to customers specification from the required grade of materials.

Slitting :

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. The Slitting is done from CRGO Mother coils available from leading Coil manufacturers in the market.

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 hysterisis and decrease of permeability

We can provide CRNGO mother coils and CRNGO Slit Coils, also known as Metal Coils, to customers specification from the required grade of materials.

It is well known that handling and processing of Non 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 hysterisis and decrease of permeability.

Toroidal inductors and transformers are passive electronic components, typically consisting of a circular ring-shaped magnetic core of high magnetic permeability material such as iron powder or ferrite, around which wire is coiled to make an inductor. Toroidal coils are used in a broad range of applications in AC electronic circuits, such as high-frequency coils and transformers.

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)

Toroidal Tech Data Toroidal cores can be supplied for use in the manufacture of current transformers, instrument transformers, etc. Typically, such cores are manufactured from grainoriented steel and fully stress relief annealed. Cores are tested to all agreed-upon technical requirements and customer specification flux density. Dimensional the feasibility of any particular combination of dimensions will be verified at the time of an enquiry. Toroidal Cores: Options Shape Round Coating (a) Epoxy edge bonding to fix shape and retain best performance (Recommended for large diameter). (b) Epoxy powder coated to a nominal thickness of 0.025(Maximum core weight = 5Kg

Material used in these cores are prime CRGO electrical steel in grades. M3, M4, M5, MOH, TCH-0, TCH-1, ZDKH. as per customers requirement while ordering specify the inside and outside diameter and strip width in mm.
