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.

P751
Guide for Wood Structures Used for Overhead Electric Transmission Lines
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.
PC135.100
Standard for Line Hardware for Overhead Line Construction
This standard covers the requirements of line hardware used in overhead lines, including clevis and eye fittings, Y-clevis fittings, socket fittings, ball fittings, chain links, shackles, triangular and rectangular yoke plates, suspension clamps, strain clamps, straight-line deadend clamps, and shoulder live line extension links.
PC135.62
Standard for Zinc-Coated Forged Anchor Shackles
This standard covers dimensions and strength requirements for anchor shackles used in overhead transmission and distribution line hardware.
PC135.80
Standard for Fasteners for Overhead Line Construction
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.
PC135.90
Standard for Pole Line Hardware for Overhead Line Construction
The requirements of inch-1 based wood pole line hardware commonly used in overhead line construction are covered in this standard. Metric pole line hardware is not covered by this standard.
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
C135.90-2014
IEEE Standard for Pole Line Hardware for Overhead Line Construction
This standard covers the requirements of inch-based wood pole line hardware commonly used in overhead line construction. Metric pole line hardware is not covered by this standard.
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
C135.2-1999
IEEE Standard for Threaded Zinc-Coated Ferrous Strand-Eye Anchor Rods and Nuts for Overhead Line Construction
Requirements for threaded zinc-coated ferrous strand-eye anchor rods and nuts commonly used in overhead line construction are covered in this standard.
C135.3-2001
IEEE Standard for Zinc-Coated Ferrous Lag Screws for Overhead Line Construction
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.
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
C135.20-1998
IEEE Standard for Zinc-Coated Ferrous Insulator Clevises for Overhead Line Construction
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.
C135.61-1997
IEEE Standard for the Testing of Overhead Transmission and Distribution Line Hardware
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.
C135.62-2009
IEEE Standard for Zinc-Coated Forged Anchor Shackles
Dimensions and strength requirements for anchor shackles used in overhead transmission and distribution line hardware are covered in this standard.
C135.63-1998
IEEE Standard for Shoulder Live Line Extension Links for Overhead Line Construction
Dimensions and strength requirements for shoulder live line extension links used in overhead transmission and distribution hardware are covered.
C135.64-2012
