Our Product Range

Toroidal Cores and 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 pit furnace under protection atmosphere, which results in features like compact volume, light, low magnetic leakage and hum & high efficiency.

Our in-depth process knowledge as well as modern production facilities allow us to successfully meet the demands of Transformer Lamination. The technical expertise of our team allows us to manufacture these for a wide range of transformers ranging from 5 VA to 50 MVA various cutting arrangments as per customer requirements. ESPI manufactures of transformer laminations using Cold Rolled Grain Oriented (CRGO). We process laminations o up to 50000 kVA in varies shapes and sizes as like 90°- 45° & 135 Basically we receive design from our customer we study and check design dimensions no load loss and suitable grade as per customer requirement and as per the design we take out EPSTEIN Samples from mother coils if the no load loss is match with the customer requirement the same coil converted into process of slitting / cutting / “V” Noching and Punching as per customer requirement.

Basically assembled core we manufacturing based on customer requirement as per specification provided by customer. Our range of Core assembling from 500kVA to 25MVA with full fledged facilities ex: Jiggs, fixtures, Core assembly Table with proper handling equipments. We are skilled knowledge in all type of core assembling as like SOD,GOD, & Various type cutting Arrangements (Overlap & Step-lap)

We have wide range of Slitting facility in CRGO and CRNGO with Fully automatic CNC Slitting Line with attached tungsten carbide blades to maintain Burr Level, Our Slitting range of Width 7mm to 1200mm. Slitting capacity in thickness 0.23mm to 0.35mm Thickness. We have installed 4 slitting lines. Our Slitting Capacity 10000 MTPA.

We are renowned as one of the supreme Core Assembling Manufacturers & Exporters from India. The unmatched quality and unsurpassable performance has attracted various national as well as international clients to place repeated orders.

The manufacturing of 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.
