• All live parts are sealed or embedded in the epoxy resin and silicon rubber, fully insulated and wholly enclosed structure, safety protection level: IP67.
• Enhanced phase separation design, independent phase insulation to avoid the fault between phases.
• Switch working position of each phase could be observed independently, which improves operation safety.
• Applicable to low temperature areas, high altitude areas, high humidity areas, high corrosion areas, low-lying areas and explosion forbidden places.
• Standard modular design to facilitate circuit extension, modification and replacement.
• Feasible to any replacement in both circumstances of any unit in fault and according user needs.
• Smaller dimention makes it more convinient to be moved, transported or replaced.
• Epoxy resin is employed instead of SF6.
