Description
Изобретение относитс к составу стекла дл высоковольтных линейных подвесных изол торов. Известно стекло, включающее Si02, AliOa, CaO, MgO, BaO, , KzO, FegOg, SO,,. Предлагаемое стекло обладает высокими электроизол ционными свойствами за счет того, что оно содержит указанные компоненты в следующих количествах (в вес. %): ЗЮг68-73 АЬОз2-6 СаО6-8 MgO2-4 ВаО0,4-4 NasO6-9,5 KsO4-5,5 РегОз0,1-0,5 ЗОз0,2-0,4 Усиление в стекле нейтрализационного эфКаО фекта при соотнощении KjO + NaaO - 0,4 позвол ет получать диэлектрик с повышенным удельным объемным сопротивлением и пониженным тангенсом угла диэлектрических потерь. В качестве примера может быть указан следующий состав стекла (в вес. %): 0,3ВаО2 ,6 MgO3,8 NaaO9,4 KsO4,6 SOs0,4 РегОз0,1 Это стекло предназначено дл изол торов, игодных как дл переменного, так и дл сто нного тока, а также с возможностью боты в услови х тропического климата. Сравнительные данные по свойствам стекла ивод тс ниже. Предмет изобретени This invention relates to a glass composition for high voltage linear suspension insulators. Known glass, including Si02, AliOa, CaO, MgO, BaO, KzO, FegOg, SO ,,. The proposed glass has high electrical insulation properties due to the fact that it contains these components in the following amounts (in wt.%): Zyug68-73 ALOz2-6 CaO6-8 MgO2-4 BaO0,4-4 NasO6-9,5 KsO4- 5.5 RegOz0.1-0.5 ZOz0.2-0.4 Strengthening the neutralizing effect of the effect in glass at the ratio KjO + NaaO - 0.4 allows to obtain a dielectric with an increased specific volume resistance and a reduced dielectric loss tangent. As an example, the following glass composition (in wt.%) Can be specified: 0.3BaO2, 6 MgO3.8 NaaO9.4 KsO4.6 SOs0.4 RegOz0.1 This glass is intended for insulators that are suitable for both alternating and for standing, as well as with the possibility of bots in a tropical climate. Comparative data on the properties of glass are given below. Subject invention
