Four Sheaves Combined OPGW Stringing Block – Fiber Optic Cable Pulley with R570 Bend Radius
Product Overview
The SHZHD10 Four Sheaves Combined Block is a specialized fiber optic stringing tool designed for stringing optical cables below Φ22mm or small cables below Φ60mm. Featuring a four-sheave structure with optimized bend radius (R570), this combined block provides superior cable protection during pulling. The compact design (760x120x480mm) and moderate weight (23.5kg) make it suitable for both tower and ground-level OPGW installation projects.
