It is a product made by applying insulation 
                            varnish to a cold-worked flat copper wire and winding multiple
                            strands of conductors, and then covering them with insulation
                            and other insulating materials.
                            
                            By handling the conductor pre-winding process in our winding 
production stage prior to the
                            coil production process, we increase transformer productivity,
 reduce load losses due to
                            multiple potentials in the conductors, and reduce insulation paper usage after winding.
                            
                            Contributing significantly to improved cooling efficiency.
                        


Insulation paper is wound around 
                            each wire to improve the wire's durability against
                            moisture and other environmental factors.
                        
The flat wires are coated with an insulation
                            varnish to prevent corona discharges that can occur during
                            transmission, distribution, and transformation.
                        


By coating the wire with insulation varnish,
                            the wire is durable enough to withstand high voltage and
                            high current to minimize power loss.
