Description

The substations can be used for the power supply of the underground current collectors from the surface through the boreholes. The substations ensure protection of the outgoing lines of the low voltage from the short-circuit currents and from the carth leakage.

The substations are connected to the high-voltage network via the cables or overhead transmission lines.
