Case Study:

1. Sag, Conductor temp, and current on typical line configurations with and without SLiM with various Range of Motions (ROM)
2. Fixed conditions:
   
   
   1. Span with anchor (dead-end) towers at same elevation
   2. Wind speed of 2 ft/sec perpendicular to line & high solar
   3. Reference temp (Tref) of 40degF (4.3degC) for line tension and relative sag calculations
   4. Assumed that the current in line is limited by sag that SLiM can remove from line
