Detailed Construction Requirements for Supply Lines

(Class H, L and T Circuits)

 

56.6    Requirements for sectionalizing with Insulators

 

A.    Guys in Proximity to Supply Conductors of Less Than 20,000 Volts (See Rule 21.3-D for definition of proximity and Fig 45 of App. G)

 

All portions of guys within both a vertical distance of 8 feet from the level of supply conductors of less than 20,000 volts and a radial distance of 6 feet from the surface of wood poles or structures shall not be grounded, through anchors or otherwise.  Where necessary to avoid the grounding of such portions, guys shall be sectionalized by means of insulators installed at locations as specified in Rule 56.7.

 

B.    Guys To Arms Supporting Conductors of Less Than 20,000 Volts

 

All portions of arm guys within 6 feet of points of attachment to wood crossarms, or metal crossarms on wood poles, shall not be grounded if the crossarms support supply conductors of less than 20,000 volts.  Where necessary to avoid the grounding of such portions, arm guys shall be sectionalized by means of insulators at locations as specified in Rule 56.7.

 

C.    Underground Overhead Guys

 

All overhead guys which are not grounded (by means of ground wires, grounded anchor guys, attachment to grounded metal poles, or otherwise) shall be sectionalized at the locations measured from each attachment to poles or structures, as specified in Rule 56.7-A (6 feet to 9 feet from attachments).

 

D.    Guys Exposed to 20,000 Volts or More

 

Guys exposed to conductors of 20,000 volts or more (see App. G, Fig. 52) shall not be sectionalized and shall have their lower ends securely grounded (by means of ground wires, anchor guys, or attachments to securely grounded metal poles or structures).  Excepted from the above requirements are:

 

Guys which are required to be sectionalized in accordance with Rule 56.6-A because of proximity of wood poles and supply conductors of less than 20,000 volts or in accordance with Rule 56.6-B; and

 

Guys which are sectionalized by wood strain insulators equipped with arcing horns and designed to provide impulse insulation for lighting conditions.

 

E.    Guys Attached To Grounded Poles or Structures

 

Guys attached to securely grounded metal poles or structures are not required to be sectionalized except as required by Rule 56.6-A because of proximity to supply conductors of less than 20,000 volts supported on wood poles, or by Rule 56.6-B.
