822MM stringing blocks are used for stringing medium size conductor (31-35 mm) in overhead transmission line construction.
We designed and manufactured 822MM blocks for single, 2 bundled, 4 bundled, 6 bundled, 8 bundled conductors stringing. The sheave is made of high strength MC nylon, can be lined with neoprene.
