Isolator

Atlas engineering company a discussion on constructional features of Double Break Isolators. These have three stacks of post insulators as shown in the figure. The central post insulator carries a tubular or flat male contact which can be rotated horizontally with rotation of central post insulator. This rod type contact is also called moving contact
Atlas engineering company make Center rotating type triple Pole outdoor on load disconnecting switches for higher line current breaking capacity for line Isolators. Earth switch can be easily installed on each pole at either end and interlocked mechanically the main switch. the auxiliary switches can be provided for man as well as for earth switch. Electrical interlock can be provided, Electrical motor drive mechanism complete with reduction gear and torque limiting safety features can also be provided, Air Break Switch Disconnectors are part of any overhead line network, providing crucial points of isolation.
