RGP-110 series horizontal rotary disconnector for 110 kV

The outdoor horizontal rotary AC disconnector of RGP-110/1250 (2000) NF1 series with drives of PR-K, PR-M, PD, PDS and more types is designed for closing and opening electrically dead high-voltage electric circuit sections as well as for grounding deenergized sections by using stationary grounding blades, which ensures safe operation at the deenergized section. Climatic category is UKhL (temperate and cold weather) according to GOST 15150 (NF according to IEC); placement category is 1 according to GOST 15543.1 for disconnectors with protection rating of IP00 according to GOST 14254-96.

RGP-110 series horizontal rotary disconnector for 110 kV

RGP-110 series disconnectors are manufactured in single-pole, two-pole, and three-pole versions with longitudinal arrangement of the poles (keel-type).

The following versions of RGP-110 series disconnectors are manufactured:

  1. RGPZ-1-110/1250(2000) NF1, with one grounding blade on the master column side;
  2. RGPZ-2-110/1250(2000) NF1, with two grounding blades;
  3. RGP-110/1250(2000) NF1, without grounding blades.

The insulation of each pole consists of two insulators. Depending on the disconnector version, insulators of various degrees of insulation are used. Upon customer’s request, disconnectors can be supplied with other types of insulators.

The horizontal rotary disconnectors are manufactured based on the drawings and technology developed by the “Electroschield TM-Samara” Group of Companies.

Made in accordance with the Corporate Standard Ts 18726720-012:2014.

The product has been certified by the National Certification System of the Republic of Uzbekistan and

Certification System of the Russian Federation (GOST-R).
