9077 high voltage DC and DC-DC blocks
The HUBER+SUHNER DC Block product line includes DC blocks (inner conductor disconnected) and DC-DC blocks (inner and outer conductor disconnected) for galvanic isolation up to 15 kV. They block high-amplitude and low frequency surge voltages e.g. occurring during regular electric railway operation along railway lines. They provide sufficient safety even in the event of the overhead high voltage lines falling to the ground.
