초록

The resistance of insulating pieces made of fiberglass reinforced plastics against the decay products of SF6, such as occur within sealed high-voltage switching devices is unexpectedly enhanced by the use of a reinforcing fiberglass made of a low-alkali silicate glass containing neither boron nor boron-compounds.

대표
청구항

A fiberglass-reinforced plastic electric-insulating member which is subject to mechanical forces and in contact with decomposition products of SF6 gas which comprises a fiberglass reinforcement made of a low alkali glass containing neither boron nor boron-containing compounds, said glass having the following composition in percentages by weight: 50-65% SiO2 20-30% Al2O2 5-20% MgO 2-10% CaO the sum of the weight percentages of CaO and MgO lying in the range of 15 to 25%, the ratio of the weight percentage of SiO2 to that of Al2O3 being at least 2 and at t...
