Zinc grounded battery

Type:Auxiliary materials

Features:in the ac interference and lightning area, to prevent damage caused by strong electric impact, not damage to the protected structures.

Release DATE:2021-06-22

The zinc grounding battery is composed of a pair or four zinc alloy sacrificial anode rods which are parallel to each other, separated by an insulating pad in the middle, and then packed together in a cotton bag with packing material. In order to prevent damage to the insulation joints and flanges caused by high-voltage surge in the process station or pipeline side, the grounding battery should be installed near the insulation device of the pipeline. The cable is welded on both sides of the insulation device (insulation joint or flange) to prevent damage caused by strong electric impact, and the grounded battery can also protect the pipeline in daily situations.

       Product type: Zinc grounded battery

  Execution standard: ASTM-B418 / GB/T4950-2002

  Main performance:

  the cathodic protection does not affect the structure itself; Building cathodic protection does not cause galvanic corrosion due to grounding.

  Scope of application:

  in the ac interference and lightning area, to prevent damage caused by strong electric impact, not damage to the protected structures.

  Detailed introduction:

  The zinc grounding electrode can be used to replace the copper or steel grounding electrode used in the past, which can solve the problems of cathodic protection and grounding at the same time, and greatly reduce the investment and cost of the project.

  Advantages:

  (1) The cathodic protection of the structure itself is not affected.

  (2) if the building cathodic protection will not cause galvanic corrosion because of grounding.

Notes:

  When used in the soil, the filler should be applied, and its proportion is: 75% gypsum, 20% bentonite, 5% sodium sulfate.
