Feature of Fixed AC Metal Enclosed Switchgear

Modular design. Each unit module can be combined and extended arbitrarily, which is an easy to scheme combination, with a wide applicable range.
The armored structure is used for the cabinet. And each compartment is separated from the other one by metal partition board.
The corrosion resistant metal is used for the operating mechanism, and bearings of rotating parts are all self-lubricating bearings. The product will not be affected by the environment, thus exempting it from regular maintenance.
In order to adapt to the power grid automation and improve the reliability of power distribution, the electric drive mechanism, control terminal unit of power distribution network and other equipment can be added. Thus, it possesses telemetering, remote signaling, and remote-control systems.
The cabinet is compact in design, using three- a three-position rotary load switch, which effectively reduces the number of components and parts, and realizes the five-preventions interlocking.
The simulated single-line diagram of the primary circuit and analog display can display the internal conditions of the switch so that the operation can be simple, correct, and safe.
