MANUFACTURING METHOD OF LIGHT-WEIGHT GROUNDING ROD

摘要

PURPOSE: A method for manufacturing a light weighted conductive ground rod is provided to offer a light weighted ground rod with an excellent strength and grounding at the same time, thereby enhancing the work efficiency. CONSTITUTION: A light weighted aggregate is sprayed or dipped with a CNT dispersion conductive hydrosol solution. The light weighted aggregate is formed with a conductive coating light weighted aggregate having the coating thickness of 5um or more and the surface resistance of 1,000Ω / sq or less. A conductive concrete is mixed to the conductive coating light weighted aggregate. An iron subsidiary material is coated with the conductive concrete. The iron subsidiary material is formed into a rod shape. A conductive silane coupling rust preventive is sprayed on the iron subsidiary material.
