Safety
Sealing of the charging unit reduces accidents.
High Reliability
Perfectly-sealed structure and excellent insulation material reduces the risk of accidents due to dielectric breakdown.
The live parts are perfectly sealed to eliminate short circuit and ground accidents and contamination of the parts.
Reliably manufactured by using a fixed frame for assembly
Easy Maintenance
Super-high pressure device is vacuumed and closed using the SF6 gas; providing easy maintainability due to low deterioration and abrasion levels. Socket-type epoxy holder allows easy socket replacement from the outside.
Cost Effectiveness
Compact structure reduces the installation area by 84 percent.
Smaller electricity room reduces the building costs.
