Product Description
The 508mm large diameter stringing block is a professional essential tool for overhead transmission line conductor stringing. It adopts high-strength MC nylon sheave and heavy-duty galvanized steel frame, with built-in ball bearings for smooth rotation and low pulling resistance. The large bending radius effectively reduces stress and avoids scratching the ACSR conductor surface during tension stringing.
We supply 1-sheave, 3-sheave and 5-sheave models for LGJ400 (ACSR400) conductor. With more than 10 years manufacturing experience in power stringing equipment, we can also provide customized stringing blocks according to your project requirements. Suitable for power grid new construction, line renovation and overhead erection projects.
