Abstract

The results of studying the effect of thermal-treatment modes and finishing conditions on the rupture strength of woven-glass tapes and fiberglass fabrics and electrical insulation manufactured from them are reported. It is shown that the complete removal of the oiling agent “wax emulsion” from the surface of glass tapes is attained after stepwise thermal treatment at 250–400°C, but the rupture strength decreases by 80% in this case. The finishing of glass tapes with 3-glycidoxypropyltrimethoxysilane after the technical oiling agent is completely removed restores their rupture strength to the level of 35–40% of the initial value (before removing the wax-emulsion oiling agent) and makes it possible to create electrical insulation with water resistance to 1100 h at 23°C and to 7 h at 80°C.
