Abstract (en)
[origin: WO7900737A1] Utilization as electrical insulator (16) of a glass-ceramic material made from blast furnace slag. The material has a content of a CaO which exceeds or is equal to 10 per cent by weight preferably amounting to approximately 22 per cent by weight, and contains also substances with the approximative values in per cent by weight stated hereinafter: 57 % SiO 6 % Al<u2>uO<u3>u 2,6% MgO 0,2% FeO 0,05% MnO 0,1% TiO<u2>u 0,2% S 0,01% P<u2>uO<u5>u 1,7% Na<u2>uO 5,0% K<u2>uO The electrical insulator constitutes a pin insulator (16) in a gas-insulated tube cable or tube capsule (10, 12) intended for high voltage.

Utilisation d'un materiau de verre-ceramique comme isolateur electrique (16) fabrique a partir de scories de haut fourneau. Le materiau a une teneur de CaO qui depasse ou est egale a 10 pourcent en poids, de preference environ 22 pourcent, et contient aussi des substances dont les valeurs en pourcentages en poids sont les suivantes: 57 % SiO 6 % Al2O3 2,6% MgO 0,2% FeO 0,05% MnO 0,1% TiO2 0,2% S 0,01% P2O5 1,7% Na2O 5,0% K2O L'isolateur electrique constitue un porte-isolateur (16) place, dans un cable ou capsule tubulaire isolee au gaz (10, 12) et destines aux courants de haute tension.
