The high rated current of 1250A allows it to distribute high levels of electrical power from the generation sources within the power plant.
The SF6 gas provides excellent insulation, heat dissipation and arc quenching properties to safely handle high currents and voltages.
The metal enclosed cabinet provides protection against environmental factors like dust, moisture, pollution and weather.
The compact design optimizes the space utilized within the power plant and allows for easy installation• The GIS technology results in components inside the cabinet being placed very close together without risk of electrical faults.
The insulation properties of SF6 gas remain constant under all operating conditions, ensuring reliability of the distribution cabinet.
The livings parts inside the cabinet - like busbars and switchgear - are safely shrouded to prevent accidental contact during work.
The zero maintenance insulating medium and sealed-for-life design extend the service life of the distribution cabinet.
Monitoring systems constantly supervise critical parameters like SF6 gas pressure, temperature and humidity within safe operational limits.
The lack of any organic material and free air inside the cabinet makes it immune to corrosion and contamination.
