Marine Sulfur Hexafluoride (SF6) gas systems are used in marine applications for electrical insulation and arc quenching in high-voltage equipment. These systems ensure safe and efficient operation of switchgear and circuit breakers onboard ships. SF6 is preferred for its high dielectric strength and thermal stability in harsh marine environments.

Size: Typically stored in high-pressure cylinders (e.g., 10L, 40L, or 50L) or bulk gas systems.

Grade: High-purity (99.9% or higher) sulfur hexafluoride (SF6) for marine applications.

Viscosity: Low viscosity gas, approximately 15.6 μPa·s at 25°C.

Buoyancy: Denser than air (5.1 times heavier), providing excellent insulation properties.

Material: Cylinders and systems made from stainless steel or carbon steel with corrosion-resistant coatings.

Pressure: Stored at high pressures (up to 3000 psi or 207 bar) in gas cylinders.

Thermal Conductivity: Low thermal conductivity (0.013 W/m·K at 25°C).

Dielectric Strength: High dielectric strength (2.5 times that of air).

Chemical Stability: Inert and non-flammable under normal conditions.

Environmental Impact: High global warming potential (GWP), requiring controlled handling.
