7350-Transmission and Distribution Line Worker

Job description

INTRODUCTION

Under general supervision, performs skilled line work in the installation, construction, maintenance and repair of overhead and underground line for power lines and/or high voltage overhead transmission and distribution lines, as well as rigging blocks, splicing wires and operating hydraulic lift buckets, and performs related duties as required.

DISTINGUISHING FEATURES

Distinguishing Features: Under general supervision, performs journey level distribution and transmission line duties requiring the ability to analyze and locate faults in transmission lines; climbing high poles and transmission towers using rigging techniques; driving overhead line trucks to remote locations, and keeping routine records of work time and materials used. Nature of work involves considerable physical effort and dexterity with frequent exposure to inclement weather and natural elements and working conditions where serious accidents or injuries may occur. Knowledge of safety measures related to work on overhead and underground lines, as well as use of respirators is necessary. Class 7350 is distinguished from class 7338 by its responsibility for journey level line worker duties involving pole, tower and underground

transmission systems of 600 to 230,000 volts or higher. The nature of

this work involves specialized training and expertise which is not

encompassed by class 7338, which typically works on systems of less than

600 volts.
