Application: It is used for stringing Single conductor, two bundled conductors detachable, four
bundled conductors detachable on overhead transmission line.
All the sheaves are mounted on ball bearings, the central sheave of bundled conductors pulleys is
mounted on thrust ball bearings. The frame of stringing blocks is made of galvanized steel.
Grounding roller system is optional for all the stringing blocks.
Note: The central sheave of 3 sheaves stringing block or 5 sheaves stringing block could be made of casting steel or high strength MC Nylon. The width of sheave for 660x110 stringing block could be selected from 75mm, 80mm, 84mm to 90mm.
