General Order 95


Section VI


Detailed Construction Requirements for Tower Lines
and Extra High Voltage Lines (Class E Circuits)


66.2    Use

Where mechanical loads imposed on towers or structures are greater than can be supported with safety factors as specified in
Rule 44 or the design of such towers and structures requires it, additional strength shall be provided by the use of guys or other suitable construction.

Where guys are used with structures capable of considerable deflection before failure, the guys shall be able to support the entire load, the structure below the point of guy attachment acting merely as a strut.

Guys shall be attached to structures, as nearly as practicable, at the center of load. They shall be maintained taut and of such strength as to meet safety factors of
Rule 44 .
