General Order 95
Section IV
Strength Requirements for All Classes of Lines
46 Vertical Strength Requirements
In computing vertical strength requirements the loads upon poles,
towers, foundations, crossarms, pins, insulators and conductor fastenings
shall be their own weight plus the superimposed weight which they support,
including that of wires and cables under the loading conditions of
Rule 43
plus that which may be added by difference in elevation of supports. The
resultant of vertical and transverse loadings on conductors shall be used
in determining the allowable and working tensions or sags in accordance with
Rule 43
.
In addition to the above a vertical load of 200 pounds at the outer pin
position shall be included in computing the vertical loads on all crossarms.
All members of structures shall be constructed to withstand vertical loads
as specified above with safety factors at least equal to those specified in
Rule 44.
