CRGO Strip Wound Cores

 

Grain Oriented Silicon Steel also call GOSS or CRGO play a vital role in the generation, transmission, distribution and use of electrical power and are one of the most important magnetic materials produced today.

 

The cold rolled grain oriented steel used in the production of G.O.S.S.'s toroidal cores consists of 3% silicon-iron alloy. Manufactured with a grain orientation facilitates very low power loss ideal for high efficiency transformers.  

 

 1. Up to 30% more flux for the same magnetizing force.

 

  2. Increased rating for a given size of transformer.

 

 3. Better regulation.

 

 4. Reduction in size and weight.

 

5. Reduced assembly time, storage and handling costs.

Limits of Tolerance

Inside diameter  ±0.8mm

Outside diameter  ±0.8mm up to 150mm

                              ±1.2mm up to 200mm

Height  -0+0.8mm for cores up to 60mm.

            -0+1.2mm for cores over 65mm

Performance Guarantee

Non-Impregnated toroidal cores are normally offered with the following standard guarantee:

0.3mm Grade M4 50Hz 1.0 Tesla limit: 19.0 A/M

Magnetic Degradation

Occurs when toroidal cores are impregnated with varnish or epoxy coated.

Light impregnated varnish +15%

Epoxy coated +40%

 

Toroidal ring core application:

Power transformer

Inductor

Instrument transformer

Audio transformer

Voltage regulators

Ballast

The advantage of ring core (Compare with EI core):

  1. Smaller size
  2. Lighter weight
  3. Less magnetic leakage
  4. Better over-load capacity
  5. Low temperature rise
  6. Easier design and mount
  7. High maximum flux density
  8. Low core losses
  9. High permeability
