2 The Main performance of ribbon zinc alloy sacrificial anode

Good flexibility, easy installation, flexible, even current distribution, high current efficiency.

3 The scope of application

It is mainly used in the soil and fresh water in high resistivity environment, the local occasions with narrow space, the protection of the pipeline in the casing, the temporary cathodic protection of the pipeline, the protection of the storage tank and the pipe network, and the grounding against strong electrical interference.

4 The product features

The diamond-shaped zinc strip anode is compounded with ASTM-B418 (Type 1 / Type 2) standards, and has good mechanical properties. The strip-shaped zinc anode is mainly used for the protection of the pipeline in the casing, the temporary cathodic protection of the pipeline, the protection of the storage tank and the pipe network, and prevents the AC interference and lightning interference of the buried pipeline from the strong current line. Strip-shaped zinc anodes are usually used in media with a resistivity lower than 2000Ω.cm. If the protected steel structure has a good coating or when the soil is wet, it can be used in media with a resistivity higher than 2000Ω.cm.

5 The Product performance of zinc strip anode

1) Good flexibility, easy installation, and easy to make various anode lengths and shapes, such as spiral and disc.

2) Uniform current distribution, high current efficiency, greater than 95%;

3) Can adapt to higher resistivity environment;

4) No need for external power supply, strip-shaped continuous conductive core, less electrical connection;

5) It can pass through narrow local occasions and difficult environments, and the application is more flexible;

6) Low resistance to ground per unit weight and high current;

7) The zinc strip anode can be used in freshwater and seawater environments, and can also be used in buried structures;

8) It can be used as a ground electrode to release AC, lightning, and protect equipment and personal safety.
