RGP-35 series horizontal rotary ac disconnector for 35 kV
The outdoor horizontal rotary AC disconnector of type RGP-35/1000 (2000) NF1 with drives of PR10, PR11, PR12, PR20, PR-K, PD and PDS series is designed for closing and opening electrically dead high-voltage electric circuit sections of 35 kV as well as for grounding deenergized sections by using stationary grounding blades, which will ensure safe operation at the deenergized section. Climatic category is UKhL (temperate and cold weather) according to GOST 15150 (NF according to IEC), placement category 1 according to GOST 15543.1 for disconnectors with protection rating IP00 according to GOST 14254-96.

RGP-35 series disconnectors are manufactured in single-pole, two-pole and three-pole versions, in the form of separate poles or assembled on the frame.
RGP-35 series disconnectors are manufactured in the following versions:
- RGPZ-1a-35/1000(2000) NF1 with one grounding blade on the part of stationary column;
- RGPZ-1b-35/1000(2000) NF1 with one grounding blade on the part of rotating column;
- RGPZ-2-35/1000(2000) NF1 with two grounding blades;
- RGP-35/1000(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.
They are manufactured based on the drawings and technology developed by the “Electroschield TM-Samara” Group of Companies.
Made in accordance with the Technical Specifications TSh 64-00212883-43:2012. The product has been certified by the National Certification System of the Republic of Uzbekistan and Certification System of the Russian Federation (GOST-R).
