Support clamps, type AA
Support clamps, type AA provides fastening of a single hollow aluminum, steel-aluminum or copper conductor on the post insulators as a part of busbar insulation of outdoor switchgear at high voltage substations. During clamp installation busbar supports should be placed so that the mount holes of post insulators and a clamp are pairwise symmetric about the conductor’s
centerline. Support clamps, type AA meet the requirements of TU U 31.2-30255335-002:2006.
