1. Introduction of flexible polymer anode cable, also known as the anode, the anode is made of conductive polymer cable, stable performance of the modified polymer made of graphite as a conductive material, as a current core copper cable wire, do a cable-like anode flexibility, resistance to mechanical damage ability, good chemical stability. Cable outer diameter 12.7mm, the sectional area of ??the internal copper core wire 11.4mm2, so the resistance per unit length R 'is 2mΩ.m-1. Mainly used for flexible anode cathodic protection of buried pipes and bottom of the tank, its development mainly to resolve overlay ① ② aging old pipe intricate network storage tank bottom wall ③ ④ long distance, small spacing parallel pipeline ⑤ high Resistivity environment; generally flexible anode has the following components: copper, conductive polymer anode materials, coke residue, knitted and woven fabrics. 2, installation instructions similar flexible anode laying cables and pipes parallel to dig a ditch anode, fill in the trench half coke powder, the anode is as flexible, then covered half the coke powder, then use the original soil (fine soil, if rock should be for soil) cover the real, a lot can be backfilled.
