Good Safety Performance

If internal arcing occurs, the housing has an internal structure weak point, it will be rushed to open, followed by the cabinet above the shutter release arc red open air overpressure stream-oriented outside the cabinet, ensure that the switch cabinet security checks.
High Security and Reliability

Load break switch sets closing, opening, earthing three at one, filled with SF6 gas encapsulated in epoxy resin housing, three-position interlock, have compact structure.
Other Advantages

Small size, light weight, maintenance-free, easy and safe to operate.
