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.
