POLYMERIC INSULATOR MANUFACTURING PROCESS Russian patent published in 1999 - IPC

Abstract RU 2143147 C1

FIELD: high-voltage polymeric insulators. SUBSTANCE: siloxane elastoplastic filled shells are produced by molding. Insulator pin is placed inside split mold, metered portion of insulating material is injected under pressure, and curing is effected in two stages; novelty is that insulating material is subjected to shearing pre-strain at definite shearing speed and straining time chosen from expression μ•γ•t•10^-3≃ 80, where μ is least viscosity of material, MPa . s; γ is shearing speed, s^-1; t is treatment time, s. EFFECT: improved capacity. 3 tbl, 3 ex
