SEL S.p.A. products

The TPR6 24 by SEL is a gas-insulated ring main unit designed for secondary distribution networks, handling voltage levels of up to 24kV. Engineered for both safety and reliability, it integrates all essential switching operations required across voltage lines of 7.2kV, 12kV, 17.5kV, and 24kV, ensuring service continuity even in fault conditions. Its construction is notable for a 'sealed for life' design, encased within a stainless steel tank that isolates all live components and switching mechanisms from external elements, thus warranting enhanced operational reliability and personnel safety. The unit adeptly manages electrodynamic stresses during operation, with user interfaces such as operating mechanisms, movable mimics, and voltage signaling lamps located on the front panel. Spring-operated mechanisms facilitate switch operations, while fuses and cable compartments are accessible via an interlocked front door, offering additional safety features. The auxiliary low voltage compartment is conveniently positioned above the main unit, enhancing overall functionality.
