Zinc Ribbon Anode

Zinc Ribbon Anode

The diamond shaped zinc ribbon anode conforms to the standard of ASTM-B418 (type 1/type2) and has good mechanical properties. Zinc ribbon anode is mainly used for pipeline inside the casing protection, temporary cathodic protection of pipeline, storage tank and pipeline protection, prevention of high voltage circuit of buried pipeline AC interference and the lightning interference .

Ribbon zinc anode are usually used in the medium with electrical resistivity below 2000Ω·cm. If the steel structure is protected by a good coating or in the case of soil moisture, it can be used in medium with electrical resistivity higher than 2000Ω·cm.

Implementing Standard

ASTM-B148

GB/T4950-2002

SY/T0019-97

Main Features

Good flexibility, simple installation, uniform current distribution, high current efficiency

Main Application

Mainly used for protection of high resistivity environment of soil and water, the narrow space of local situations, casing pipe, pipeline temporary cathodic protection, storage tank and pipeline protection, anti-electromagnetic interference of the grounding grid.

Product Performance

1. Good flexibility, easy to install, easy to make anodes in various length and shapes such as spiral shape and disc shape.

2. Uniform current distribution, high current efficiency, more than 95%

3. Can be adapted to environment with higher resistivity;

4. No need for external power supply, having a continous conductive core and less electric connection;

5. Can pass through the narrow local place and harsh environment, more flexible application;

6. Small ground resistance and large current per unit weight;

7. Zinc anode can be used in fresh water and sea water environment, as well as be used in underground structures.

8. Can be used to connect earth electrode, releasing exchanging and thunder and lightning to protect equipment and personal safety.
