CRGO Core Assembly

The CRGO (Cold Rolled Grain Oriented) Core Assembly is an essential part of a transformer, crafted from high-grade CRGO magnetic silicon steel. These cores are made up of thin CRGO sheets, also known as laminations, that are designed to optimize the flow of magnetic flux and minimize air gaps between the sheets.

We specialize in the precision assembly of core coils, ensuring optimal performance and reliability. Our expertise lies in crafting transformer components that form the backbone of electrical distribution systems worldwide.

Role of Mother Coils:

  • Improved Efficiency: Enhances transformer performance by minimizing energy losses.
  • Durability: High-grade materials ensure long-lasting operation and reliability.
  • Energy Savings: Optimized design contributes to significant energy savings.

CRGO Core Assembly FAQs

What is the purpose of CRGO Core Assembly in a transformer ?
The CRGO Core Assembly forms the core of a transformer, which is responsible for ensuring the efficient flow of magnetic flux and minimising air gaps between laminations.
How is CRGO Core Assembly manufactured ?
Required CRGO Cut lamination, Frame part, insulation paper, tie rod, and core bolt for core assembly manufacturing, it is done by Manual process. The core assembler sets the dimensions as per design and starts core building by maintaining window height, leg centre, etc The CRGO Core Assembly is typically manufactured using high-grade CRGO magnetic silicon steel, which is coated with carlite to ensure optimum losses and efficient working of the transformer. The core is annealed to restore the magnetic properties and relieve stress, ensuring lower eddy current losses.
