Properties:
Sulphur hexafluoride is liquid under normal temperature and pressure. It’s a colorless, odorless, non-toxic and non-corrosive gas. Its melting point is -50℃, boiling point is -63.8℃, and the density is 6.12g/L(20℃ 0.1MPS). It is an excellent electrical insulator.
Application:
Sulphur hexafluoride is an excellent insert insulating gas widely used in high-voltage electric equipments and ground cables, mainly including electronic equipments, radar, particle accelerator, transformer, lightning arresters, refrigerant etc.
Storage:
In cool, dry and ventilated warehouse.
Transport:
With symbols indicated in GB19-73. The coefficient of the filling cylinders should not be higher than 1.33kg/L.
Packing:
In seamless steel cylinder(40L, 12.5L, 10L, 8L, 4L)(Normally, the pressure is 15MPa, the filling coefficient<1.37kg/L).
