General Order 95

 

Section IV

 

Strength Requirements for All Classes of Lines

 

48.7       Metallic Service and Meter Poles

Metallic service and meter poles shall be designed and constructed so that the poles and parts thereof will not fail or be seriously distorted at any load less than the maximum working loads (see
Rule 43 for loadings) multiplied by the safety factors specified in Table 4 , Rule 44 . The safety factors specified in Table 4, Rule 44 shall be applied as follows:

 

Tension: The yield strength of the metal used shall be divided by the safety factor specified in Table 4 , Rule 44 to determine the maximum allowable working stress.

Compression: The critical buckling strength of the material used, as determined by applicable formulas employing the effective slenderness ratio and yield strength, shall be divided by the safety factors specified in
Table 4 , Rule 44 , to determine the maximum allowable working stress.

Shear: The yield strength of the material used shall be divided by the safety factors given in
Table 4 , Rule 44 to determine the maximum allowable working stress.

 

Note:      Added July 26, 1966 by Decision No. 71009. Revised January 21, 1992 by Resolution SU–10.
