Type DR9
Center-Break, Gang-Operated
Outdoor Air Disconnect Switch
Three Phase
8.25 thru 420 kV Voltage
600-2000A
The DR9 switch is a three-pole, center-break disconnect switch rated for applications from 8.25 kV to 420 kV maximum voltage and 600A to 2000A.The three-pole units are gang-operated by a single motorized or manual drive system. The contacts of each pole of the DR9 switch meet in the middle. When a switch pole unit either opens or closes, the connecting rod between the insulator stacks rotates the stacks in opposite directions.  As the insulator stacks rotate, the blades, connected to the top of the insulator stacks, are simultaneously opened or closed.

A galvanized structural steel channel base supports the insulators and live parts. The mechanical parts and rotor bearings are designed for durability to withstand cantilever stresses, ensuring long-lasting service in all types of environments.  All parts have been designed to be uniform across the product line.  As a result, parts are easier to stock and are more readily available from the factory.
