The amplitude of electricshaft-frequency electric field by modulating the current of ICCP system is 10 times greater than that of corrosion current.
调制阴极保护电流而产生的轴频电场最大的幅值比调制腐蚀电流所产生的电场大10倍之多。

In addition, as the shaft is vertical the electric generator can be installed on one end above the water-without any need of waterproof boxes.
此外，由于轴是垂直的，发电机可以被安装在水面以上的一端——从而无需任何防水箱。

In addition, since the shaft is vertical, the electric generator can be installed at the top, above the water-so there is no need for any waterproof boxes.
