The exposed surface of all guys and guy rods shall be of corrosion–resisting material.


B.      Size

The size and ultimate strength of guys crossing in spans over Class H, L, T or C circuits shall be not less than as specified in
Table 9 and shall also be such as to provide safety factors not less than those specified in Rule 44 for the loads imposed by the construction involved under the loading conditions specified in Rule 43

C.      Strength

Where guys are used with poles or similar structures, capable of considerable deflection before failure, they shall be able to support the entire load, the pole below the point of guy attachments acting merely as a strut. Stranded wires shall be used when the ultimate strength of the guy exceeds 1,800 pounds. Anchor rods and their appurtenances shall meet the same strength requirements as the guy wire or strand (See
Rule 44 ).
