Удельное сопротивление этого стекла составл ет 10 0м-см. Наиболее близким к предлагаемо по составу вл етс электроизол ц , вюпючающее, вес онное стекло 52-58 SiO 8-10 1,5-2 5-7 8-10,5 8-13 2,5- -20,1-0,5 Указанное стекло имеет следующ диэлектрические характеристики:. 2 дельное сопротивление, оМ-см: ю объемное поверхноЫО-1 , стное Тангенс угла диэлектричес2- -4 ,5 ких потерь Пробивной градиент , кВ эфф/мм 20 Цель изобретени - улучшение ктроизол ционных характеристик. Указанна цель достигаетс , что электроизол ционное стек- включающее SiOj,,Al20a СаО, , Na20, КоО ,окисел марганца, ержит в качестве окисла марганМп О- при следующем соотношении понентов, мас.%: 69,5-70,3 Si О, «,0-5,0 А1 7,5-8,3 3,0-3,5 10,0-П ,0 ,0-3,7 . 0,5-1,0 Стекло синтезируют при НбО-Т+УО С ырабатывают при 1250-12бО°С. Составы стекол и результаты изуи их основных технологических, ико-механических и электрических йств приведены в таблице. The invention relates to electrification, namely, to the technique of electrically insulating materials, and can be used in insulator production plants. Electrically insulating glass l is known, comprising, in wt.%; Si 025.6-5b, 2 6.3-6.6 Sab12.3-12.7 MdO3.8-6.5 MnOj1i, 0-19.0 NajO3.8-5 For the production of the specified Steel, use a non-deficient cleanup sand, chalk, dolomite, etc. The resistivity of this glass is 10 m-cm. The closest to the proposed composition is electrical insulation, wypuyuchayuschuyu, weight onnogo glass 52-58 SiO 8-10 1.5-2 5-7 8-10.5 8-13 2.5- -20.1-0, 5 The indicated glass has the following dielectric characteristics: 2 practical resistance, OM-cm: 10-D volume surface-1, external Tangent of dielectric angle 2-4, 5 losses Loss of penetration gradient, kV eff / mm 20 The purpose of the invention is to improve thermal insulation characteristics. This goal is achieved that the electrically insulating glass-including SiOj ,, Al20a CaO, Na20, CoO, manganese oxide, as MarganMn O- as the oxide in the following ratio of ponents, wt.%: 69.5-70.3 Si O, “0-5.0 A1 7.5-8.3 3.0-3.5 10.0-P, 0, 0-3.7. 0.5-1.0 Glass is synthesized at NbO-T + PP. It is produced at 1250-12 ° C. The compositions of the glasses and the results of their main technological, iko-mechanical and electrical properties are given in the table.
