Single-pole indoor disconnectors RVO-10/400 are designed to switch on and off energized sections of a high-voltage electrical circuit in the absence of load current and to change the connection diagram; to ensure safe work in the disconnected area; for turning on and off charging currents of overhead and cable lines, no-load current of transformers and currents of small loads. By design, single-pole disconnectors of the RVO series are of vertical cutting type and consist of a base, support insulators and a contact system. The base serves as the basis for installing insulators and attaching the disconnector to the support. There is a grounding bolt on it.
Disconnectors are manufactured in the UHL category 1 version for operation at altitudes up to 1000 m above sea level; It is recommended to install in rooms where fluctuations in temperature and humidity do not differ significantly from fluctuations in the open air and there is relatively free access to outside air, for example in tents, bodies, trailers, metal rooms without thermal insulation, as well as in the casing of a complete device or under a canopy, in order to avoid direct impact and precipitation on products. Temperature range from -60 °C to +40°C.
