SF6 CIRCUIT BREAKER• SF6 (sulphur-hexafluoride) gas possesses

a unique combination of properties, making it an excellent gas for use in circuit breakers. The properties are:

• High insulation strength• Excellent interrupting capability• Chemically stable even at high

temperature• Non-toxic• Non-flammable

Cont.

• Insulating capability is three times greater than that of air and at 3 bar (43.5 psi) it is even better than that of transformer oil
