Insulation in Oil-Immersed Transformers The most common insulation today for high-voltage windings in a transformer is an enamel coating on the wire, with kraft paper used between layers. Low-voltage strips can be bare with paper insulation between layers. The use of paper wrapping on strap conductor is slowly being...
AC Needs More Insulation Than DC for the Same Working Voltage Level For the same working voltage, the potential stress on the insulation is less than in the case of a DC system than...
WHY CABLES ARE INSULATED? An INTRODUCTION With the exception of power transmission cables that are on electric poles, almost all the cables that are in use today are insulated. The level or degree of insulation...
