10KN Four Sheaves Combined Block: OPGW & Fiber Optic Stringing Quadrant Block

The SHZHD10 Four Sheaves Combined Block is a precision-engineered stringing tool specifically designed for the installation of OPGW (Optical Ground Wire) and fiber optic cables. By adopting a four-sheave quadrant structure, this block ensures that delicate cables maintain a safe R570 bend radius during traction. This segmented design effectively distributes pressure, preventing signal loss or fiber breakage caused by sharp angles.

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.
