For high-voltage systems from 3.3kV to 24kV, AEC's
metal-clad and metal-enclosed switchgear provide centralized
circuit control . A complete line of functional units
is available for control and protection of motors, transformers,
generators, distribution lines, rectifiers, M-G sets,
and similar power equipment. Each standard self-contained
unit utilizes basic world reliable components including
vacuum circuit breakers, magnetic blast breakers, instruments,
relays, meters, instrument transformers, and control
devices.
Convenient access to all components and use of vertical
lift horizontal drawout breakers shortens the times
necessary for inspection and maintenance.
