This
Poletop SF6 Gas Puffer Switches are designed for
load interrupting switching or sectionalizing of overhead distribution 27Kv,
400A and are also designed for eliminating the weight, potential hazards, fires,
explosions and maintenance cost often associated with oil-filled equipments
or air swithches.
