Cathodic Protection Sacrificial Zinc Anode

          In the cathodic protection system, solid state de-coupler as dc isolation and AC coupling device is not only used to prevent the cathodic protection current from reaching a predetermined threshold voltage, but also can conduct inductive alternating current.

• Product features:

1. Stable performance: it is conductive to the coupled AC current on the pipeline, which can effectively reduce the induced AC interference voltage.
2. Able to withstand the expected large impact: in the case of induced lightning or single-phase short circuit fault of power lines, it can withstand the expected large impact or fault current, and the fault state is short circuit mode.
3. Wide range of application: adapt to field environmental conditions, meet the requirements of easy installation and maintenance on site.
4. Long life: Reasonable use, service life can exceed 20 years.

• Product application:

1. Transient, transient and long-term overvoltage protection.
2. Solid state de-coupler can be used in electrified railway, high voltage AC transmission and distribution, substation, power plant and other AC interference sources to alleviate the ac interference of buried steel pipeline.
3. Ac grounding and DC isolation of electrical equipment in the cathodic protection system.
