Section VIII

 

Detailed Construction Requirements for Communication Lines
(Class C Circuits)

 

86.6    Sectionalizing and Grounding Requirements

The general requirements governing the sectionalizing of guys by means of insulators are based upon the exposure or proximity of the guys to supply conductors. For definition of guys exposed and guys in proximity to supply conductors see
Rules 21.5C and D respectively (see also Appendix G, Figures 44 and 45 ). The following requirements shall apply to the treatment and sectionalizing of guys.

 

A.    Where Not Exposed to Supply Conductors

Guys attached to or passing poles or structures supporting only communication conductors need not be sectionalized or grounded, provided such guys are not exposed to supply conductors of 250 - 22,500 volts and are not in proximity to supply conductors of 0 - 35,500 volts.

 

Note:    Revised March 29, 1966 by Decision No. 70489; August 9, 1966 by Decision No. 71094 and November 20, 1979 by Decision No. 91030.

 

B.    Sectionalized Because of Exposure or Proximity to Supply Conductors

 

(1)    Overhead Guys Exposed to Supply Conductors of 250 - 22,500 Volts: Ungrounded overhead guys which are exposed to supply conductors of 250 - 22,500 volts, and which are not in proximity to supply conductors of 0 - 22,500 volts shall be sectionalized by means of insulators located as specified in Rule 86.7A1 (see Appendix G, Figure 44 ).

 

Note:    Revised March 29, 1966 by Decision No. 70489 and August 9, 1966 by Decision No. 71094.

 

(2)    Guys in Proximity: Every overhead or anchor guy, any portion of which is in proximity to a wood pole and supply conductors of 0 - 35,500 volts (see Appendix G, Figures 45 , 48 and 49 ) shall be sectionalized by means of insulators as specified in Rule 86.7A2 or Rule 86.7B , and no portion in proximity to such supply conductors shall be grounded. Excepted from this requirement are anchor guys, and grounded overhead guys, which are attached to poles at a level less than 8 feet but not less than 6 feet below the level of supply conductors provided the level of the guy attachment is at or below the level of communication cable messenger attached to the same pole (see Appendix G, Figures 48a and 49f ).

Also excepted from this requirement are anchor guys, and grounded overhead guys, which are attached to poles at a level less than 6 feet but not less than 4 feet below the level of supply conductors of 0 - 750 volts provided such guys are extensions of or attached to a cable messenger, are in the same vertical plane (or extension thereof) as the messenger, and are below the guard arms required by
Rule 87.7B for such a messenger (see Appendix G, Figure 48a ).

 

Note:    Revised March 29, 1966 by Decision No. 70489; August 9, 1966 by Decision No. 71094 and November 20, 1979 by Decision No. 91030.

 

C.    Guys Exposed to Supply Conductors of 22,500 Volts or More

Portions of guys exposed to supply conductors of 22,500 volts or more shall be securely grounded, and such guys need not be sectionalized unless sectionalization is required by
Rule 86.6B2 because of proximity to supply conductors of 0 - 35,500 volts (see Appendix G, Figure 52c ).

 

Note:    Revised March 29, 1966 by Decision No. 70489; August 9, 1966 by Decision No. 71094 and November 20, 1979 by Decision No. 91030 and March 9, 1988 by Resolution E3076.

 

D.    Guys Attached to Grounded Poles or Structures

Guys attached to securely grounded metal pole or structures are not required to be sectionalized except as required by
Rule 86.6B2 because of proximity to supply conductors of less than 35,500 volts supported on wood poles.

 

Note:    Revised March 29, 1966 by Decision No. 70489; August 9, 1966 by Decision No. 71094 and November 20, 1979 by Decision No. 91030.

 

E.    Anchor Guys through Supply Conductor Levels

An anchor guy which passes through the level of supply conductors at positions other than between pole pin positions or outside of the outer pin positions shall have insulators above and below the level of supply conductors at locations as specified in
Rule 86.7B (see Appendix G, Figure 49d ).
