RGP-220 series outdoor horizontal rotary disconnector for 220 kV
The outdoor horizontal rotary AC disconnector of RGP-220/1250(1600, 2000) NF1 series with SRCJ2 and SRCS type drives is designed for closing and opening electrically dead high-voltage electric circuit sections as well as for interruption of open-circuit currents of transformers and charging currents of air and cable lines.
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.
Single-pole, two-pole and three-pole versions of RGP-220 series disconnectors are manufactured with longitudinal arrangement of the poles (keel-type).
The following versions of RGP-220 series disconnectors are manufactured:
- RGPZ-1-220/1600 NF1, with one grounding blade on the master column side;
- RGPZ-2-220/1600 NF1, with two grounding blades;
- RGP-220/1600 NF1, without grounding blades.
The insulation of each pole consists of two insulators. Depending on the disconnector version, insulators of various insulation degrees are used. Upon customer’s request, disconnectors can be supplied with other types of insulators.
Made in accordance with Corporate Standard Ts 18726720-012:2014.
