BUSHING REINFORCED INSULATORS
The bushing insulators are produced for switchgears of both indoor and outdoor installation. The insulators are intended for an insulation and mounting of the current-carrying parts in electrical devices, switchgears of power stations and substations, packaged switchgears, compounds with outdoor switchgears or transmission lines of alternating voltage from 6 to 35 kV with a frequency up to 100 Hz. The insulators are reinforced with flanges made of cast iron or aluminum alloy using portland cement. The busbars are made of aluminum.
