COMPARATIVE PERFORMANCE OF CONVENTIONAL 220 KV INSULATOR STRINGS AND MULTI-CHAMBER INSULATOR-ARRESTERS STRINGS UNDER SPECIFIC ICE CONDITIONS OF RUSSIA
Multi-Chamber Insulators-Arresters (MCIA) combine characteristics of insulators and arresters. A prototype of 220 kV voltage class MCIA String is intended for use in different environments including iced environments. The results of ice tests showed that multi-chamber system (MCS) installed at the insulators do not reduce the electrical strength of insulator strings under ice conditions defined as thickness 30 mm on the rotating rod and 100 uS/cm of applied water conductivity.
