Forced current sacrifices the advantages of anodic cathodic protection technology

Forced current cathodic protection technology is in the circuit into a series of DC power supply, with the help of an auxiliary anode, direct current to the protected metal, and then the protected metal into a cathode, the implementation of protection. Advantages: 1: high driving voltage, can be flexibly controlled in a wide range of cathodic protection current output, used for a large protection range of occasions 2: the selection of insoluble or micro-soluble auxiliary anode, can be long-term cathodic protection 3: under the premise of severe erosion or high resistivity environment is also used 4: The protection range of each auxiliary anode bed is large. When the pipeline anticorrosive layer is of good quality, the protection range of a cathodic protection station can reach tens of kilometers.
