Jay Bee Laminations Limited specializes in manufacturing and supplying electrical laminations, slit coils, and assembled cores made from Cold Rolled Grain Oriented (CRGO) Silicon Steel and Cold-Rolled Non-Grain-Oriented (CRNGO) Steel. These products are essential components for transformers, UPS, and inverters used in the power industry.

Their manufacturing facilities, covering 10,878 square meters, are fully equipped with in-house capabilities for slitting, cutting, assembling, and testing CRGO and CRNGO electrical steel cores. They also have an in-house laboratory for testing raw materials and finished goods, as well as a tooling division for blade sharpening. Their production processes focus on meeting the stringent quality standards required for power and distribution transformers, capable of serving transformer manufacturers up to the 220 kV class. As of March 31, 2024, they utilized 83% of their installed capacity.

Their company primarily supplies CRGO electrical steel cores to transformer manufacturers, a material that requires specialized expertise in manufacturing and handling due to its sensitivity to physical stresses. To ensure the safety and quality of transformers, all transformer core materials must adhere to the Bureau of Indian Standards (BIS) regulations.

Their clientele includes manufacturers of transformers ranging from 11 kV to 220 kV classes, focusing on power and distribution transformers. The CRGO steel core is a critical component, accounting for 25-30% of a transformer’s total cost and playing a vital role in reducing transmission and distribution losses in the electricity supply infrastructure, underscoring its importance in power distribution.
