General
UNFLN-36 series indoor SF6 load break switch is a three-phase AC 50-60Hz, rated voltage of 3.3kV, 6kV, 10kV, 11kV, 12.5kV, 13.8kV, 15kV, 17.5kV, 20kV and 24kV indoor switchgear, control and protection for industrial and mining enterprises, power plants and substations, electrical facilities, and for frequent operation place.
High quality breaker shell made by APG. full copper inside operating mechanism and low resistance on connection part.
Reliable operation mechanism uses for both incoming panel and feeder panel.
Visible window design can see inside mechanism of SF6 tank of break. High purity of SF6 guarantee insulation, double quality test for prevent gas leakage.
It works in XGN switchgear and UNARMU
Standard
All UNISUN Electric breaker are in conformity with IEC standards, and recommendations IEC60694、IEC6227-100. Breakers in conformity with specific country standards can also be supplied. (IEEE, GB).
