SILICONE THROUGH INSULATOR AND METHOD FOR ITS PRODUCTION Russian patent published in 2012 - IPC H01B17/26 

FIELD: electricity.

SUBSTANCE: silicone through insulator includes current lead and bearing sleeve with metal flange, which envelops current lead so that a cavity is formed, which is fully filled with insulation layer of silicone rubber - vulcanised polymeric compound on basis of liquid synthetic rubbers the oligomers of which contain end functional groups. Compound has specific mechanical strength σ_r. Bearing sleeve is L_sl long and made from dielectric material with specific mechanical strength σ_sl and it speads throughout the length of insulating layer, and flange is provided with collars enclosing the bearing sleeve and spreading along it through length L_f. At that, the following ratios are met: σ_r<σ_sl; 1<L_sl/L_f<σ_sl/σ_r.

EFFECT: improving protection reliability of insulating body and areas adjacent to it against damage, partial or complete destruction or depressurisation, and increasing electrical and mechanical strength of through insulator as a whole.
