What Is Sulphur Hexafluoride (SF₆) Gas?
Sulphur hexafluoride (SF₆) is an inert, non-flammable insulating gas widely used in electrical power systems due to its exceptional dielectric strength and arc-quenching properties.
It is commonly applied in:
- High-voltage switchgear (GIS systems)
- Circuit breakers
- Power transmission equipment
- Electrical substations
Its stability and insulation performance make it one of the most critical gases in modern power infrastructure.
SF₆ Gas Technical Specifications
- Purity Grades: 99.9% / 99.99% / 99.999% (UHP)
- Moisture Content: ≤ 2–5 ppm (high purity grade)
- Acidity (HF): Controlled within industrial standards
- Pressure Range: 50–200 bar (depending on cylinder type)
- Contamination Control: Oxygen & nitrogen strictly limited
Cylinder Surface Treatment Options
- Standard industrial cleaned cylinders
- High-polish internal surface (low contamination applications)
- Nickel-plated cylinders for ultra-high purity SF₆ storage
Correct cylinder selection is critical for maintaining SF₆ gas purity and performance stability.
