Flexible anode (polymer cable anode) Polymer cable anode is made of conductive, stable performance modified polymer, graphite powder as conductive material. The life of the aggregate cable anode is not determined by its mechanical stability, but by its electrical efficiency. When the current density is about 0.7A·m-2. If petroleum coke powder is used as filler, the allowable current density can be raised to 2M &.m-1. If the maximum current output per meter of cable anode is about 20mA, the service life is 10 years. The lover. The outer diameter of the cable anode is 12.7mm, and the cross-sectional area of the internal copper core wire is 11.4m㎡, so the unit length of the resistance copper cable core is used as a current conductor. The cable-shaped anode has good flexibility, strong resistance to mechanical damage and high chemical stability. This process depends on the local current density and therefore on the resistivity of the soil. A reaction similar to equations (7-3) and (7-4) occurs at the flexible anode. As a result, graphite is consumed over time, and at these points the polymer cable anode is made from a conductive, stable modified polymer, with graphite powder as the conductive material. If there is no petroleum coke back filler, the anodic reaction is carried out according to equations (7-1) and (7-2), followed only at the cable anode.
