Rigging for High Voltage Work

Click for video

Summary

This 51-minute DVD explains the basic principles of rigging for high-voltage work and demonstrates how these principles apply in three typical rigging jobs. Particular emphasis is placed on safety issues and on properly planning a rigging job. Covers how to approach rigging near energized lines. Describes how to plan a job and how the amount of strain involved affects the size and type of equipment selected. Describes how to rig to remove strain from a transmission insulator.
