Corrosion Inhibitor on Ground Connections
Corrosion Inhibitor on Ground Connections
(OP)
I was wondering if anyone out there had experience with application of corrosion inhibitors on ground connections. There appear to be two main areas: one being to prevent the bolt from corroding and the other area to assure electrical continuity across two faces.
The issue that I raise is complicated by the issues of copper mating with SS (cable tray) or Aluminum etc. It seems some "ground" connectors are made of a copper alloy; does this mean that they have a wide compatability to a variety of materials wiithout any additional treatments?
Finally, there is probably an issue as to whether the product is used outside in a marine environment (offshore oil & gas platform) versus inside a "clean" electrical room.
Products that I know about that have been used in these circumstances are Burndy Penetrox A, A13 and E (in copper or zinc particulate formulations), T & B Kopr-Shield, and CRC Heavy Duty Corrosion Inhibitor 06026.
Any advice/experience towards correct application of these products would be appreciated. I have some calls into mfgrs as well.

Pentrox or a equivelent is used on ground conductors,when for example connecting a zinc coated crimp termination to a copper ground bar with a stainless steel screw.
Another method is to use zinc coated ground bars, crimps,and bolts which are then coated with pentrox.
To asure good electrical continuity periodic ductor test should be carried through out the life of the installtion.
