This guide provides general recommendations for maintaining wood poles and wood structures. The recommendations are based on sound asset management and engineering principles, safety and liability considerations and decades of field experience by many utilities. Included are technical explanations as required to cover: inspection of wood structures and attachments; supplemental preservative treatments; methods of restoring strength to pole sections weakened by decay, insects, woodpeckers and mechanical or other damage; wood structure system management.

This guide consolidates useful information, methods, and reference materials that define the state of the art in the design of wood pole transmission structures, commonly in the 69 kV through 345 kV range, into one document. This guide addresses application of wood in transmission structures, characteristics of wood, methods of analysis, loadings, connections, non-wood members, erection and framing, quality assurance, electrical considerations, testing and maintenance.

Existing Standards |
Requirements for threaded zinc-coated ferrous strand-eye anchor rods and nuts commonly used in overhead line construction are covered in this standard.
|
Zinc-coated steel lag screws of the fetter drive, gimlet point, and twist drive types commonly used in overhead line construction are covered in this standard.
|
|
Zinc-coated ferrous clevises for spool-type insulators commonly used for supporting or dead-ending conductors in line construction are covered. The specifications for spool-type insulators used with these clevises are covered in ANSI C29.3-1986.
|
|
Requirements for mechanically testing load-rated line hardware for use on transmission and distribution facilities are described. Items specifically addressed in this standard include clevis and eye fittings, Y-clevis fittings, socket fittings, ball fittings, chain links, shackles, triangular and rectangular yoke plates, suspension clamps, and strain clamps. This standard is intended to cover routine acceptance testing. It is not intended for initial design tests.

Dimensions and strength requirements for shoulder live line extension links used in overhead transmission and distribution hardware are covered.
|
|
Dimensions and strength requirements for anchor shackles used in overhead transmission and distribution line hardware are covered in this standard.
|
|
The requirements of inch-based: (1) zinc-coated ferrous carriage bolts, machine bolts, double-arming bolts, double-end bolts, washer-head bolts, eye bolts, eye nuts, and washer nuts; (2) zinc-coated ferrous lag screws of the fetter drive, gimlet point, and twist drive type; (3) washers; and (4) staples, commonly used in overhead line construction, are covered. Metric bolts, nuts, and lag screws are not covered by this standard.

Correcting dimension errors in "Table 5 - Dimensions of hex nuts". It appears a copy and paste error was made from the "Table 4 - Dimensions of square nuts". Table 4 is correct, but Table 5 has incorrect dimensions for hex nuts.
