General Order 64
Section VI
Detail Construction Requirements For Supply Lines
65 Guys And Anchors.
(a) Use:
Where then mechanical loads to be imposed upon poles or other supporting
structures are greater than can be safely supported by the poles or structures
alone, additional strength shall be provided by the use of guys, or other
suitable construction.
Guys should also, when
necessary, be used wherever conductor stresses are unbalanced, as at angles and
dead ends.
When guys are used with
poles or similar structures capable of considerable deflection before failure,
they shall be able to support the entire stress, the pole acting merely as a
strut.
(b) Material: All guys shall be galvanized if of
steel. Only stranded steel cable shall
be used as guy wires where the ultimate strength of the guy exceeds 1800
pounds.
All anchor rods used in
connection with guy wires or similar attachments shall preferably be
galvanized.
Note - Guy wire and anchor rods should be given more liberal safety factors than those specified in Table 3 when used in territories where fog conditions prevail.
(c) Anchor Guard: The ground end of all guy wires attached to ground anchors in urban districts and where exposed to traffic elsewhere shall be provided with a substantial wood or metal guard not less than 8 feet long. (See Appendix E, Fig. 16A.)
(d) Clearance: Wherever two or more guys are attached tot eh same pole carrying supply conductors there shall be at least 1 foot vertical separation between the points of attachment. Where two or more guys are attached to the same pole and the same grounded anchorage there shall be at least 1 foot vertical separation between the points of attachment at the pole. (See Appendix E, Figs. 18B and 19B.)
(e) Guy Fastenings: Guy wires where attached to anchor rods should be protected by suitable guy thimbles. Cedar and other soft wood poles, to which any guy having a strength of 5000 pounds or more is attached, shall be protected by the use of suitable guy shims, and in this case guy hooks, lag-bolts or other suitable means shall be provided to prevent the guys from slipping along the poles.
