DesNo71094 go95 rule 86.6

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 definitions of guys exposed and guys in proximity to supply conductors see Rules 21.3-C and D respectively (see also App. G, Figs. 44 and 45). The following requirements shall apply to the treatment and sectionalizing of guys.

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 sup- ply conductors of 250-21,000 volts and are not in proximity to supply conductors of 0-21,000 volts.

(1) Overhead Guys Exposed To Supply Conductors Of 250-21,000 Volts: Ungrounded overhead guys which are exposed to supply conductors of 250-21,000 volts, and which are not in proximity to supply conductors of 0-21,000 volts shall be sectionalized by means of insulators located as specified in Rule 86.7-A1 (see App. G, Fig. 44).

(2) Guys In Proximity: Every overhead or anchor guy, any portion of which is in proximity to a wood pole and supply conductors of 0-21,000 volts (see App. G, Figs 45, 48 and 49) shall be sectionalized by means of insulators as specified in Rule 86.7-A2 or Rule 86.7-B 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 App. G, Figs 48a and 49f). Also excepted from this requirement are anchor guys, and grounded over- head 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 87.7-B for such a messenger (see App. G, Fig. 48a).

Portions of guys exposed to supply conductors of more than 21,000 volts shall be securely grounded and such guys need not be sectionalized, unless sectionalization is required by Rule 86.6-B2 because of proximity to supply conductors of 0-21,000 volts. (See App. G, Fig. 52c.)

Guys attached to securely grounded metal poles or structures are not required to be sectionalized except as required by Rule 86.6-B2 because of proximity to supply conductors of less than 21,000 volts supported on wood poles.

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 86.7-B. (See App. G, Fig. 49d.)

Strikeout and Underline Version
Rule 86.6

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 sup- ply conductors of 250- ~~21,000~~22,500 volts and are not in proximity to supply conductors of 0-~~21,000~~22,500 volts.

(1) Overhead Guys Exposed To Supply Conductors Of 250-~~21,000~~22,500 Volts: Ungrounded overhead guys which are exposed to supply conductors of 250- ~~21,000~~ 22,500 volts, and which are not in proximity to supply conductors of 0-21,000 22,500 volts shall be sectionalized by means of insulators located as specified in Rule 86.7-A1 (see App. G, Fig. 44).

(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- ~~21,000~~22,500 volts (see App. G, Figs 45, 48 and 49) shall be sectionalized by means of insulators as specified in Rule 86.7-A2 or Rule 86.7-B 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 App. G, Figs 48a and 49f). Also excepted from this requirement are anchor guys, and grounded over- head 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 87.7-B for such a messenger (see App. G, Fig. 48a).

C. Exposed To Supply Conductors Of More Than ~~21,000~~22,500 Volts

Portions of guys exposed to supply conductors of more than ~~21,000~~22,500 volts shall be securely grounded and such guys need not be sectionalized, unless sectionalization is required by Rule 86.6-B2 because of proximity to supply conductors of 0- ~~21,000~~22,500 volts. (See App. G, Fig. 52c.)

Final Version
Rule 86.6

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 sup- ply conductors of 250-22,500 volts and are not in proximity to supply conductors of 0-22,500 volts.

(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 86.7-A1 (see App. G, Fig. 44).

(2) Guys In Proximity: Every overhead or anchor guy, any portion of which is in proximity to a wood pole and supply conductors of 0-22,500 volts (see App. G, Figs 45, 48 and 49) shall be sectionalized by means of insulators as specified in Rule 86.7-A2 or Rule 86.7-B 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 App. G, Figs 48a and 49f). Also excepted from this requirement are anchor guys, and grounded over- head 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 87.7-B for such a messenger (see App. G, Fig. 48a).

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