Abstract
An electrical insulating paper having 40-80 wt % of aramid fibrid, 10-50 wt % of aramid pulp, and 10-50 wt % of aramid short-cut. The aramid pulp is para-aramid pulp with a length of 0.5-6 mm and has a Schopper Riegler value of 15-85; the aramid fibrid is para-aramid fibrid; and the aramid short-cut is para-aramid short-cut. The paper shows a high dielectric strength and tensile index. A method for manufacturing the paper and an insulated conductor that includes the paper.
