CSR is what? Chambers prefabricated single-sided servicing: models

CSR is a device that is designed forreception of the electric power. Models work in an alternating current network. Its frequency should be 50 Hz. In a two-phase current network, devices can not be operated. To date, models are available with a different nominal voltage parameter. Some configurations are designed exclusively for operation at distribution substations.

Also there are devices for maintenanceunderground. Separately, there are a number of models for receiving electricity from transformer substations. The development of CSR abroad is very active. In order to understand this issue in more detail, it is necessary to consider specific modifications.
