BHA-10/630-20 U3 loading switches
Switches of loading are intended for inclusion and shutdown
under loading of sites of a chain of alternating three-phase
current of the industrial frequency of 50 Hz, with a rated voltage
up to 10 kV, and also grounding of the disconnected sites by means
of grounding conductors.
Switches are intended (together with the drive) for work in cases of the complete distributing devices (CDD), cameras of the national teams of unilateral service (KSO), cases of the complete transformer substations (CTS) and other electric devices of internal installation on tension class to 10 kV of three-phase alternating current of the frequency of 50 Hz for systems with the grounded and isolated neutral.
