LESSON 3
INSPECTION
Critical Task: 113-588-1003
OVERVIEW
LESSON DESCRIPTION:
In this lesson you will learn about maintenance on telephone poles. You might wonder just what
maintenance is needed, but you will agree afterwards that it is very important.
TERMINAL LEARNING OBJECTIVE:
There is no terminal learning objective for this lesson.
INTRODUCTION
Telephone pole maintenance is very important. The pole dries out. This must be detected since strong
winds could cause it to break at a weak point. Termites, other bugs, and ants are other problem areas for
the Wire Systems Installer. These create unseen problems and must be detected to ensure the pole
remains erect for a long time.
Records of where poles are located, when they were installed, and the type and size of the pole used are
very important. Within this subcourse, you will be given information on pole line records that must be
maintained by the person or persons installing the telephone poles.
You, the Wire Systems Installer, are the maintainer and the record keeper for telephone poles and
associated equipment.
PART A - POLE LINE PATROLLING AND INSPECTION
1.
General. Poles, guys, and braces require a careful and continuous preventive maintenance
program to prevent deterioration of the line and eventual line failure. Exposure to weather and
interference by construction activities, electric light and power circuits, trees, vehicles, and so forth,
make the plant vulnerable to service interruption.
