Hi Alan,
So far all I can find is this: http://www.pjm.com/planning/to-standards/downloads/20020520-va-general-criteria.pdf
On page 11, Table 1 under spacers, it say's 18" spacing, no preformed wire spacers allowed. This is for on the poles, but it should be the same for your situation.
Hope this helps,
Tim
