shallow MMO anodes
Certification:
Application area
Shallow MMO titanium anodes are appropriate for high aggressive soil. Poorly soluble anodes can be installed horizontally in trenches or vertically in holes.
Technical details
Shallow anode is MMO titanium electrode with corrosion resistant connecting cable 2 m long.
Working element is a tubular electrode made of mixed metallic oxide. Contact with the cable is inside the electrode. For isolation of contact joining a specially developed chemically resistant solution on the basis of polymeric compound is used. An additional isolation of the place of cable outlet is made with thermocontracting couplers.
Quantity of anodes in a grounding, distance between them, type of disposition of anodes are determined by the project of cathodic protection.
Grounbeds are assembled into the electric circuit. Connection to the feeding cable of CP Station is made through the control equipment by means of main cable. Joining of an anodic cable to the main cable is carried out by using thermit welding or cord fasteners. We use thermocontracting couplers for isolation of cable joinings.
The hollow space around the anode should be filled with a coke-mineral activator (KMA) produced by Chemservice in order to reduce spreading resistance of anodic current and to slow down anodic dissolution.
