Disconnector type RDZ-220/2000

1501000
Outdoor disconnectors of the RDZ-220/1000 UHL1, RDZ-220/2000 UHL1, RDZ-220/3150 UHL1 series are designed to switch on and off de-energized sections of a high voltage circuit under voltage, as well as to ground the de-energized sections using stationary grounding devices.

The disconnectors are manufactured by the company in a single-pole version, partially disassembled for transportation, and are supplied (depending on the order) for installation of a single-pole, two-pole or three-pole device, which is connected to the drive at the installation site.

The disconnector is controlled by an electric motor drive of the PD-5UHL 1 or PDG-5UHL1 or PDG-8UHL1 type. The earthing switches are manually controlled by the actuator type PD-5UHL1 or PDG-5UHL1. Details
