Suspension glass insulators type are used for isolating and fixing the wires to the overhead power lines, power distribution facilities and substations of AC voltage over 1000 V and a frequency up to 100 Hz. Operated at an ambient temperature of -60 to +50oC.
Insulator has the special aerodynamic profile isolating assembly parts. Its distinguish specifications are increased diameter of glass cap and no under ribs. This profile is effective in desert areas. (Examples: E1-E4).
It is possible to use glass part of bigger diameter as an “umbrella” and to protect a string from atmospherical condensation and pollution.
