12F401 - 3-over-3 Double Circuit Line Angle (Including Underbuild)

Notes:

1. 50’ minimum pole height without communication attachments. 60’ minimum pole height with communication attachments.
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 accidental contact with jumpers, primary down guys must be equipped with 144" fiberglass guy strain insulators (MID 939267).
4. The upper circuit on 3-over-3 double circuit structures is an express feeder. Connect all transformers, risers and 1Ø and 2Ø taps to the lower circuit
5. Crossarms to be set to split the angle in the line. Guy should be set in the plane of the crossarm if possible.
6. New overhead double circuit construction is allowed in rural areas only.
