Hot Stick Maintenance of 69 kV Suspension [Single Pole Structures]

This 25-minute video shows procedures for maintaining 69 kV single-pole suspension structures, using hot sticks. Three procedures are demonstrated: How to maintain insulators on a Z-arm structure. How to maintain insulators on a two-arm structure. How to change the lower crossarm of a two-arm structure. Note: This video is of poor quality and was filmed many years ago, but the information it delivers is still valid. (Courtesy Hubbell)
