RV (RV, RVO, RVF) series indoor disconnectors
RV(Z), RVO(Z), RVF(Z) series indoor disconnectors are designed for closing and opening electrically dead high-voltage electric circuit sections as well as for grounding deenergized sections by using stationary grounding blades.
Climatic category is N(U) according to GOST 15150; placement category is 2 according to GOST 15543.1 for the disconnectors of IP00 protection rating according to GOST 14254-96.
RV(Z) series indoor disconnectors and RVF(Z) series indoor disconnectors with bushing insulators are made in three-pole design.
RVO(Z) series indoor disconnectors are made in single-pole version.
Examples of the designation of the disconnectors when placing an order and in the documents of other products are as follows:
- “Disconnector RVZ-2-0.25-10/630 N2 according to TSh 64-002122883-007:2007”;
- “Disconnector RVZ-2-0.25-10/630 N2, export, according to TSh 64-002122883-007:2007”.
The embodiment of the disconnectors is as follows:
- disconnectors have no grounding blades;
- disconnectors with one grounding blade on the fixed contact side;
- disconnectors with one grounding blade on the post insulator side;
- disconnectors with one grounding blade on the movable contact side;
- disconnectors with one grounding blade on the bushing side;
- disconnectors with two grounding blades;
- according to the location of the drives.

The insulation of each pole consists of two insulators. RV(Z), RVO(Z), and RVF(Z) series disconnectors are made with porcelain and polymer insulators.
The disconnectors 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 64-00212883-007:2007.
The products have been certified by the National Certification System of the Republic of Uzbekistan and Certification System of the Russian Federation (GOST-R).
