KMT sf6 switchgear maintenance Analysis

Apr 28, 2008 · One estimate has put the annual cost of this maintenance as 9% of the equipment value - that is 45% over the first five years. This does not include any other safety and insurance costs involved. At transmission voltages, the relatively low number of circuit-breakers means that a small specialist team can carry out maintenance on SF6 equipment.
