Anchor Shaft Corrosion Cathodic Protection Systems

To protect your guyed tower, we recommend an anchor shaft excavation inspection for all guyed towers which are more than a few years old if they have not had a corrosion cathodic protection system. (CPS). Since 99% of anchor shaft corrosion & shaft failures normally occurs in the lowest 1′ of the anchor shaft, it is prudent to carefully excavate & inspect the entire length of each anchor shaft. Installing our high quality Cathodic Protection System (CPS) ensures the safety, security & life expectancy to your guy wire tower structures. Our cathodic protection systems have proven they can last over 30 years when used in conjunction with a resilient anchor shaft protective coating.

SKU Product Price Qty

Each of our high potential magnesium anodes has the following physical properties:

    - Backfill material in each anode package: 75% Gypsum, 20% Bentonite, 5% Sodium Sulfate.

    - Connecting core wire is 20′ long, 8 gauge stranded copper, heavily jacketed with HMWPE coating.

    17 lb Magnesium anode “core”. Material consists of:

    - Magnesium / High quality 98.839 %.

    - Aluminum 0.01 % maximum.

    - Manganese 1.0 % maximum.

    - Silicon 0.05 % maximum.

    - Iron 0.03 % maximum.

    - Nickel 0.01 % maximum.

The following is our procedure for measuring a CPS / cathodic protection system at each anchor fan plate location:

Temporarily disconnect the anode wire connection clamp from the guy wire anchor shaft or its fan plate, Using a volt meter, test for the DC voltage present between the anchor fan plate & the anode wire connector. Finding a DC voltage reading between the anode wire & the anchor in excess of -1.15 volts is a good sacrificial CPS. A DC voltage reading of less then -.90VDC is too low & may be a sign of a dormant, disconnected or depleted CPS which requires additional high quality anodes added to the anode bed to bolster the DC voltage until voltage achieved is upwards of -1.15VDC or higher. Contact us for additional anodes since low anode voltages may not be preventing anchor shaft corrosion or if you have questions.
