The comment has been deleted as, in the username owner's opinion, having posted it, it added nothing useful by way of assistance within the 15 minute time-out for editing posts by registered usernames, to the orignal poster's plight.

Have you seen transparent insulating material used as protective shield inside switchboards?.

Tycho Electronics (Raychem) makes a heat-shrinkable tubing rated up to 36kV for bus bar insulation. You slip it over the bus bar and shrink it with a heat gun or propane torch. See the following link:

http://www.gvk.com.au/pdf/heatshrink/high_volt_protection.pdf

They also have it in the form of a tape called HVBT that can be applied to unevenly shaped objects (bus joints, bends, tees, etc.), and is heat-shrunk the same way. My company uses this very often for insulating HV cable to bus connections or cable to transformer bushing connections in place of hand-wrapped tape.
