Features & Applications
• Tested per OHSA & ASTM F711
• Relieve strain from an insulator string to permit
removal from energized lines
• Normally used on a single string of insulators
• Also used for multiple strings where conductor-end
hardware permits attachment
Maximum load rating for each of the strain-carrier
assemblies listed below is 15,000 lb. per insulator string.
Common Features For All Units
Listed
• Two 2"-dia. Epoxiglas poles
• Yokes are 26" wide on pole centers
• 2” adjustment in 6" increments on five
stainless-steel pins per pole
• 12"-long Strain Jacks
Standard Duty Strain Carriers (6,500 lb.)
Features & Applications
• Same basic use as the two-pole strain carrier
• Relieves strain while removing a single string of
insulators
• Distribution strain carrier has a compression deadend
yoke at the hot end
• Insulator-conductor hardware features a compression
lever-type action, gripping tighter as the load
increases
• Various shoes furnished with the kit fit conductors
from 0.292" through 0.806" (No. 2 through 397.5
ACSR)
• Maximum load rating for each distribution strain-
carrier assembly listed below is 6,500 lb. per insulator
