SPA has developed a power supply unit for cathodic protection (CP) systems which is simple to operate, has web connectivity and is designed with thorough long term durability and reliability in mind. Importantly, it does not rely on any proprietary components, and this addresses one of the primary shortcomings of various proprietary power supply units which have been incorporated in CP systems in Australia.

One of the most important aspects of cathodic protection installations is achieving accurate monitoring and minimal maintenance of the CP components embedded in the concrete and soil. Reliable reference electrodes are essential for accurate monitoring and the adjustment of the CP system, leading to optimum protection of the structure.

Stainless steel, carbon steel and polyethylene casing spacers from Advance Products and Systems are the first choice in ensuring the integrity of a carrier pipe when installed in casing. When comparing wood skids to casing spacers, we find that wood skids’ liability is higher.

The original concept for the discrete anode was developed some 20 years ago. Since then many types of discrete anodes have been installed in a large number of concrete structures around the world. SPA’s discrete anodes are constructed using grade 1 Titanium conductor rods & conductor bars, and is manufactured under strict quality assurance procedures.
