WebHigh silver content brush for propeller shaft grounding. The CA20 range of silver brushes are designed to provide the best combination of conductivity and wear resistance. The … WebOur shaft grounding (shaft earthing) systems drain any current sent out by the anodes. This prevents corrosion and premature failure of vital parts of the propulsion train. Generally … WebA propeller shaft and propeller become electrically insulated from a vessel by lubricating oil film from the tail shaft bearings. This causes an electrical potential between the vessel shaft and the rest of the ship which accelerates corrosion, this will happen even if the vessel has cathodic protection or an impressed current system. blacksmith handles
