Nylon Three Sheaves Stringing Block – 5KN Overhead Line Conductor Pulley for Triple Bundle

Product Overview

The SH80S Three Sheaves Stringing Block is a lightweight nylon conductor block designed for overhead transmission line stringing. Specifically engineered for the 'one pull three bundle' method, this block can pull three bundles of small cross-section conducting wire simultaneously. The triple bundle stringing block and pull board are made of aluminum alloy/MC nylon mounted on ball bearings, with the groove lined by a neoprene ring or wear-proof interchangeable nylon/aluminum wheels. The frame is made of galvanized steel, and the pulleys can be supplied with fixed (B), swivel-type (C), or hook with safety lock (D) connections.
