CRGO Core Laminations

Working Principle

CRGO Core Lamination is made of highly permeable silicon steel sheets, which are stacked to form the iron core and mainly take two core roles:

Efficient magnetic conductivity: in the alternating magnetic field (after the transformer primary side coil is energized), the high magnetic permeability of silicon steel sheet can let the magnetic lines of force pass through efficiently, forming a closed magnetic circuit, realizing the electromagnetic induction between the primary side and the secondary side coil, and completing the voltage transformation.

Suppressing eddy current: The silicon steel sheet itself is very thin (0.23~0.5mm) and the surface is coated with an insulating coating, which can limit the eddy current to a very small range of a single piece, greatly reducing eddy current loss, avoiding overheating of the iron core, and improving the efficiency of the equipment.

Product Feature

Low Loss Design

Silicon steel sheet + insulation coating, greatly reducing eddy current loss and hysteresis loss, more energy efficient than the whole core, long-term operation can significantly reduce the cost of electricity.

Flexible Size

Can be cut to any length, width, hole position and shape according to customer's requirements, perfectly matching the design of transformers of different capacities and voltage levels.

Material selection

Support non-oriented / oriented silicon steel, amorphous alloy and other materials, can be energy-saving projects, special working conditions, such as high temperature and high humidity environment, to do targeted selection.

High material utilization

Precision shearing process reduces the waste of trimmings and lowers the cost of raw materials.

Short production cycle

Faster processing of semi-finished products compared to complete cores, shortening the customer's production lead time

High structural strength

Precise size + fastening hole design, good mechanical stability of the core after stacking, anti-vibration, anti-shock, suitable for outdoor, vehicle and other harsh environments.
