A choice of anodes
Cathelco offer a choice of anodes according to the requirements of different types of wind turbines. Stand-off disc anodes are typically used for monopile structures where the bracket can be mounted on the transition piece. As the anode is at a distance from the structure the need for a di-electric shield is eliminated. In other cases linear surface mounted anodes can be used where the backing shield provides di-electric protection.
Stand-off anodes are circular with current emitting faces made from mixed metal oxide on a titanium substrate. The surface mounted anodes are made with tubular elements mounted on an ABS plastic backing sheet. They are all rated to a depth of 140 metres.
