HORIZONTALLY ROTATING TYPE OF РДЗ SERIES

The disconnect switch is designed for switching on and off the de-energized sections of the high-voltage electrical circuit, as well as grounding the disconnected sections with the groundwires that are integral with the disconnect switch.  The climatic version is УХЛ, placement category is 1 according to GOST15150.  The disconnect switch is made in a single-pole or three-pole version. Insulator columns are made of cylindrical post  insulators in compliance with GOST 25073, GOST 9984, GOST 13873, GOST 28856.  The creepage distance according to GOST 9920 (IEC 815-86, IEC 694-80) for the category of external insulation I -1,6, II * is 2.25.

The weight of the disconnect switch with the drives is determined when ordering.

 The disconnect switch and their drive(s)  comply with the following reliability indices: 

— mechanical wear resistance, cycle.          — 2000

— Mechanical resource, cycle.                             — 10000

— MTBF  (mean time between failures), cycle.                                — 2000

— average service life, years                            — 30

— – average service life up to the first medium repair provided that the mechanical resource is not used, years, minimum  – 10.

The disconnect switch shall comply with the GOST 689 requirements, these specifications and documentation for the disconnect switch and drive.
