Disconnectors RDM, RDMZ

Outdoor two-column disconnectors RDMZ-LE series are designed for deenergized circuit HV section switching and switch off sections earting by means of eathing devises

 

Applications

Disconnectors RDMZ-35-LE are used in distribution transformer substations of 35 kV

Disconnectors are produced for rated currents 1000 and 2000 A with normal or reinforced insulation
