TPR6 HP PLUS for primary distribution systems has been developed after many years of experience in the secondary distribution with TPR6 series.
Compared to TPR6, TPR6 HP PLUS is characterized by higher performances; its short-time withstand current is up to 31.5kA and rated current up to 2000A . TPR6 HP PLUS is particularly suitable for power plants with high performances.

Construction Characteristics

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.
Gas work is not required, neither for installation at site nor for extension of the switchgear.
The operating mechanisms of the vacuum circuit-breaker, three-position switch-disconnector and three-position disconnector are located outside the gas compartment and are therefore accessible at any time.
Current and voltage transformers are usually located outside the gas compartment.
Cables are connected from the front. They are arranged at one level side-by-side and at a user-friendly mounting height.
