What size bullwheel and stringing blocks are recommended for use with ACSS?
Southwire recommends a minimum bullwheel bottom groove diameter of 35 times the conductor overall diameter. Southwire recommends never using a v-groove tensioner with ACSS. Southwire recommends a stringing sheave bottom groove diameter of 20 times the conductor overall diameter. For severe angle pulls, this diameter may need to be increased.
