Product Description
10KN Four Sheaves Combined Block: OPGW & Fiber Optic Stringing Quadrant Block
Technical Specifications
Manufactured under ISO9001 certification, this combined block provides high-load capacity with protective geometry:
| Item Number | Model | Outline Size (mm) | Rated Load (KN) | Bend Radius (mm) | Weight (kg) |
|---|---|---|---|---|---|
| 20141 | SHZHD10 | 760 x 120 x 480 | 10 KN | R570 | 23.5 kg |
- Applicable Optical Cables: Diameter below Φ22 mm
- Applicable General Cables: Diameter below Φ60 mm
- Structure: Combined type with four protective sheaves
Key Technical Advantages
- Optimal Bend Radius Protection: The R570 bend radius is specifically calculated to exceed the minimum bending requirements of most OPGW and fiber optic cables, ensuring zero signal degradation
- Four-Sheave Combined Design: Distributes the hauling tension across four independent sheaves, reducing localized mechanical stress on the cable jacket
- Fiber-Safe Sheave Material: Equipped with smooth, non-metallic sheaves (typically nylon) to prevent abrasion and metallic contamination of the optical cable
- High Load Stability: With a 10KN rated load, it handles significant pulling forces required for long-span transmission line projects
Applications
- OPGW Stringing Operations: Steering and guiding OPGW cables through towers and angles
- Fiber Optic Cable Installation: Safe deployment of telecommunication fiber optics in overhead utility grids
- Power Line Communication (PLC) Projects: Installing communication-integrated grounding wires
Professional Buyer FAQ
Q1: Why is the R570 bend radius important for OPGW stringing?
Optical fibers are sensitive to micro-bending. The R570 radius ensures the cable transitions smoothly through the block without exceeding the critical bend limit, preventing internal fiber fractures.
Q2: Can this block accommodate larger power cables?
Yes. While optimized for Φ22mm optical cables, the sheave width allows for general power cables with a diameter up to Φ60mm.
Q3: How is the block secured during operation?
The unit features a heavy-duty central hanging eye, allowing it to be suspended from tower cross-arms or utility poles for reliable alignment.
