CRGO
"BIS CERTIFIED CRGO"

“Elite Transformers & Switchgears, Jalandhar, only use BIS Certified CRGO (Laminations)”. Transformers CRGO (lamination) shall be made of BIS standard steel sheet and strip in accordance with certain Indian Standard (IS) specifications. BIS certification for CRGO (Cold Rolled Grain Oriented) steel signifies that the product meets the standards set by the Indian government for quality, safety, and performance. CRGO steel is widely used in electrical transformer cores due to its superior magnetic properties.

Winding

All windings are made from electrolytic grade copper or aluminium as per customer requirements. Aluminium or copper is procured from Hindalco & Nalco. The conductor is in the form of triple or double paper covered insulated strips and wire. The insulating paper is kraft paper from BILT (Ballarpur Industries Ltd.).

The type of windings commonly used is single or multi conductor spiral or crossover and disc type. The types adopted also depend on the rated current and voltage levels. For voltage above 11 KV, Disc Winding is adopted generally.

 

 

 

The solid insulation used in the windings is either in the form of rectangular spacers or common blocks assembled from pre-compressed high-density pressboard procured from high quality Indian manufacturers like RAMAN, SANAPATTI Mysore. It is this component of winding which imparts the desired mechanical strength. Besides optimum design, the quality of raw material plays a vital role in the reliability of a transformer under fault conditions. Hard pressboard blocks insulate the end transformer winding each other and the layers are insulated from each other by interlayer insulations.
