12F325 - Double Circuit Flat Line Angle

Revision 9
Jun 15, 2022

 

Notes:

  1. Minimum 8’-0”. Only to be installed on 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. Crossarms to be set to split the angle in the line. Guy should be set in the plane of the crossarm if possible.
  4. To avoid conductor contact during fault conditions, install conductor spacers (Compatible Unit I0320A-B) on span lengths greater than 150 feet.
  5. This assembly is intended for primary conductors with a maximum working tension of 2,500 lb/Ø or less. For framing conductors with a maximum working tension between 2,500 lb/Ø and 4,000 lb/Ø refer to Assembly Unit 12F385.
  6. 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.
