Abstract RU 2091890 C1

FIELD: electrical engineering; instrumentation engineering; supporting rods of polymeric suspension insulators on power transmission lines. SUBSTANCE: glass-reinforced plastic insulation rod has slits and threaded hole along rod axis that receives stud. Threaded joint is locked by means of conical hole in bushing which embraces glass-reinforced plastic rod and is fitted onto it by means of nut. This prevents spontaneous loosening of nut.
