Abstract

A carbon sliding strip for a collector has a rupture control device, comprising a pressure line (9) incorporated directly in the carbon strip (1), a device (13) for producing increased pressure in the pressure line and a pressure detector (15), which detects the sudden drop in pressure which occurs if the channel begins to leak. Since at least part of pressure line wall is made directly from the carbon material, the pressure control device responds even to small cracks in the carbon and immediately shows wear and rupture.
