Notes:

  1. Minimum 7’-0” for poles up to 45’ in height. Increase spacing to 8’-0” for poles 50’ and taller.
  2. Engineer must specify the size & number of down guys and anchors depending on conductor design tension, line angle, available down guy lead and span length. Refer to T&D Guideline 4-6 and Compatible Unit Sections A and G.
  3. To avoid conductor contact during fault conditions, install conductor spacers (Compatible Unit I0320A-B) on span lengths greater than 150 feet.
  4. This assembly is intended for 795 kcmil AAC (Arbutus) primary conductor installed with a maximum working tension of 4,000 lb/Ø. For framing conductors with a maximum working tension of 2,500 lb/Ø or less refer to Assembly Unit 12F326.
  5. New overhead double circuit construction is allowed in rural areas only. Refer to T&D Guideline 4-23-7.0 — Design Practices for Constructing Double Circuit Lines.
