TPR6 Plus is a maintenance-free, factory-assembled and type-tested medium-voltage switchgear. It is three-pole metal-enclosed and SF6-insulated. Vacuum circuit-breaker, switch-disconnector and disconnector modules are available.
The core of the switchgear consists of hermetically welded containers made of corrosion-resistant stainless steel, accommodating the primary devices (circuit-breaker and three-position switch). The switchgear is sealed for life. The switchgear modules are interconnected by solid-insulated busbars outside the gas compartments.
