ENhanced TECnology

General Features Pad mount switchgear is designed for distribution automation system with combination of circuit breaker, load break switch and direct circuit. Multiple selection of load break switches and circuit breakers make the end user distribution line `s system more flexible. SF6 gas insulated switchgear and Solid insulated switchgear will provide full support with various choice of controls in order to complete distribution line system.
