Journeyman Event – B-phase Insulator Change-out

Event Summary: 

This event will consist of changing out all primary post type insulator assemblies on a 40’ B2.24 (B1-1) pole.  The line shall be grounded prior to untying the primary conductors.  Either grounding method can be used (EPZ or Bracket Grounding).  Rubber Gloves can be removed if the EPZ Grounding method is used, however they cannot if the Bracket Grounding Method is used.  Armor Rods and tie wire will be used to secure the conductor to the insulators.  Armor rods can remain on the conductor, but new tie wire will need to be used to secure the conductor to the new insulators. The primary conductor can be floated. 

Event Rules:

1. Teams will have 5 minutes to set up & ask questions for this event.  Time will start on the judge’s signal.
    
2. The B-phase line must be de-energized before climbing begins. Failure to do so will result in a 10-point deduction.
    
3. The B-phase line shall be grounded prior to crossing the neutral. Failure to do so will result in a 2-point deduction.
    
4. Tools and equipment must always be on the provided tarp when not in use.
    
5. Teams will be provided with pre-cut tie wire prior to entering the event area.
    
6. A Top-Groove Double Tie shall be used to secure the conductor to the insulators (See diagram below).  Failure to use the Top-Groove Double Tie will result in a 2-point deduction.
    
7. All connections shall be brushed.
    
8. All four post-type insulator assemblies shall be replaced.
    
9. Time stops when all climbers are below the neutral, the grounds are removed, the line has been re-energized, and the groundman calls “TIME.”
    
10. Judging will continue until the event site is restored to its original condition and the team has left the event site. Points can be deducted after time stops.
     
11. All general rules apply.
