The present invention pertains to an electrical insulating paper comprising 40-80 wt.% of aramid fibrid， 10-50 wt.% of aramid pulp， and 10-50 wt.% of aramid short-cut， the aramid pulp being para-aramid pulp with a length of 0.5-6 mm and a Schopper Riegler of 15-85. Preferably， the fibrid is para-aramid fibrid and/or the shortcut is para-aramid shortcut. More preferably， the fibrid is para-aramid fibrid， and the shortcut is para-aramid shortcut. It has been found that a paper meeting the above requirements shows an increased value for the product of the dielectric strength (expressed in kV/mm) and the tensile index (expressed in Nm/g)， as compared to systems comprising only two of the cited components， or less than 40 wt.% of aramid fibrid. The paper is relatively easy to manufacture， and has good tear strength. The paper is particularly suitable for use in insulated conductors.
