A: Initial investment cost is low, and maintenance fees are generally not required during operation.

B: High utilization of current protection, no over-protection occurs.

C: No interference to adjacent underground metal facilities, suitable for industrial areas, long-distance pipelines without power supply, and protection of small-scale scattered pipelines.

D: Provides both grounding and protective functions.

E: Construction techniques are simple, requiring no special maintenance or management on a daily basis.

In the anti-corrosion applications of grounding equipment, sacrificial anode protection technology is superior to impressed current protection technology. This is because the sacrificial anode is directly connected to the grounded equipment, without the need for a power source and requires no maintenance. It not only provides anti-corrosion protection but also aids in reducing the grounding resistance, hence its recognition and widespread use.

2)强制电流阴极保护 technology

Forced current cathodic protection involves串联 a direct current power supply in the circuit, utilizing an auxiliary anode to direct the direct current towards the metal to be protected, thereby turning it into a cathode and implementing the protective measures.

High driving voltage, allowing flexible control of cathodic protection current output over a wide range, suitable for larger protection areas.

Also suitable under harsh corrosive conditions or high resistivity environments.

When using insoluble or slightly soluble auxiliary anodes, long-term cathodic protection can be achieved.

D: Each auxiliary anode bed has a broad protection range. When the pipeline anti-corrosion coating quality is good, the protection range of a cathodic protection station can reach dozens of kilometers.

E: Even pipes with poor anticorrosion coating quality can achieve complete cathodic protection.

To achieve maintenance-free objectives, it is advisable to use sacrificial anodes for the anti-corrosion of the line grounding device. The reason is that the anode is buried underground and requires no maintenance. Another significant factor is that the anode filling material has a noticeable effect of reducing resistance.
