Technical specification for corrosion inhibitors for grounding grid resistance-reducing materials

1 Scope

This document specifies the technical requirements, inspection methods and rules, marking, packaging and storage of corrosion inhibitors for inorganic resistance reducing materials for grounding grids. Require. This document applies to the resistance reduction materials of steel grounding grids for industrial and civil power installations. For pure copper (or copper-plated steel) grounding grid resistance reducing materials The technical conditions for using corrosion inhibitors are for reference. Note. Corrosion inhibitor for grounding grid resistance-reducing material means that it can be used to inhibit and slow down the resistance-reducing material after being evenly mixed with the grounding grid resistance-reducing material on the steel used to make the grounding grid Corrosive substances such as metals.
