Greetings Dana,
You may consider sheathing the bare copper wire in a product
appropriately rated for the outdoors and UV etc... Possibly
Liquidtight Flexible Nonmetallic Conduit (LFNC), electronics
insulating sheathing, continuous grommet channel, heat shrink tubing,
or some type of weather stripping product.
Stainless steel cable clamps ("p" clips); bare, coated, or with EPDM
bushing/lining may also be a possible solution.
Heyco Products may be a good source to search for a solution:

If time and budget allows you may like to consider using an
appropriately rated insulated wire with a green outer finish. #6 AWG
USE-2 with green insulation may be an option. The insulation can be
removed where needed for connection to the ground lugs etc.
Hope you find a good solution for the project.
Best regards,
----MATT

[RE-wrenches] Looking for insulated #6 bare standoff

Good Morning Wrenches,
I am required to keep the bare #6 copper from touching the aluminum frame
work of a Array Technologies tracker where it is not mechanically connected
by a pass-through ground clamp on a tracking array [dissimilar metals] and
am looking for a lead on an insulated standoff or strap to hold the #6 bare
copper as it passes from panel to panel and rail to rail. The plans examiner
would accept pass through clamps & this is a worst case-spendy solution to
this.
I have searched the inquired at local electrical warehouse &on the internet
and to no avail under "insulated strap" & "insulated cable standoff".
Has anyone else encountered his & what did you use? Where did you source
this strap?
I remember seeing something like this in the fuzzy past & cannot recall
where I saw it or what it was for.
Thanks for any suggestions.
