Influence of the Fines on the Dielectric and Tensile Breakdown of Oil-Impregnated Paper

Masao Murata; Kojiro Nakata

The ideal composition of fibers for insulating paper has been clarified by investigating the influence of the shape of fines on dielectric and tensile breakdown of oil-impregnated Kraft paper for oil filled (OF) cable at 105N/M oil. Furthermore, the pulp refining methods for producing such insulating paper have been investigated.

Quantitative estimation of paper formation and its effect on oil-impregnated paper

Masao Murata; Kojiro Nakata; Akiharu Yokoyama

It is generally considered that paper formation, if it is good, will have little effect on the dielectric breakdown strength of oil-impregnated Kraft paper for oF cable. However, little is known about defining good formation quantitatively.
