Use of enameled copper wires for creation of gap in ferrite cores
2003
WE ARE ONE OF THE LEADING MANUFACTURERS OF FERRITE TRANSFORMERS , ADAPTERS & TORROIDS IN FERRITE TRANSFORMERS. WE ARE FINDING IT VERY DIFFICULT TO ACHIEVE THE REQUIRED INDUCTANCE IN UNGAPPED CORES .
WHEN WE USE ENAMELED COPPER WIRE FOR THE GAPPING BETWEEN THE CORES
, WE ARE ABLE TO EASILY ACHIEVE THE REQUIRED INDUCTANCE MY QUESTION IS , IS THIS A STANDARD PRACTICE ? , IS THERE ANY PROBLEMS BY DOING THIS .
CAN ANY ONE PLEASE HELP US OUT , IT WILL INCREASE OUR PRODUCTIVITY BY 80 %.

The use of a conductive material in the gap may give heating problems due to eddy current effects if the flux is high or the area of the copper is significant. The usual trick is to use hollow glass microspheres of the correct diameter for the gap in an epoxy mix.
