12F385 - 795 AAC Double Circuit Line Angle Framing (Obsolete - See 12F325)
Revision 2
Aug 12, 2022
Notes:
- Minimum 7’-0” for poles up to 45’ in height. Increase spacing to 8’-0” for poles 50’ and taller.
- 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.
- Crossarms to be set to split the angle in the line. Guy should be set in the plane of the crossarm if possible.
- To avoid conductor contact during fault conditions, install conductor spacers (Compatible Unit I0320A-B) on span lengths greater than 150 feet.
- This assembly is intended for 795 kcmil AAC (Arbutus) primary conductor installed with a maximum working tension of 4,000 lb/Ø. For tangent spans less than 150' refer to Assembly Unit 12F384.
- Refer to T&D Guideline 4-23-1.0 for max. allowable line angle.
- 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.
