Compatibility of liquids and polymers in mixed EHV dielectrics

摘要

In a laminated, composite dielectric of polymer and paper, the paper-faced film of polymer behaves like a paper tape mechanically, while the cellulose protects the polymer against the direct effects of discharges which may occur in liquid filled cavities such as the butt spaces. The paper ply also facilitates initial impregnation and its maintenance under thermal cycling.
