Abstract (en)
[origin: US4375527A] 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.
Abstract (de)
Die Widerstandsfähigkeit von glasfaserarmierten Kunststoffisolierkörpern (5,6) gegen die Abbauprodukte des SF6, wie sie in gekapselten Hochspannungs-Schaltanlagen auftreten, wird unerwartet gesteigert, wenn Verstärkungsglasfasern aus einem von Bor und Borverbindungen freien und alkaliarmen siliziumhaltigen Glas vorgesehen sind.
