    In earlier systems, the Oil circuit Breakers are used. But later they were replaced by the SF6 filled Circuit Breakers. The special reason to use this type of breakers is, the high arc quenching property and insulation property of SF 6 gas under high pressure. The breakers which are placed in 220kV switchyard at Pannipitiya are rated as 245kV.
