Product Description
25KN Optical Cable Wire Gripper: Damage-Free Clamping Tool for OPGW & ADSS Fiber Cables
Product Overview
The Suntech series Optical Cable Wire Gripper is a highly specialized engineering tool designed for the safe, damage-free tensioning, stringing, and sagging of delicate overhead fiber optic cables. Engineered specifically for OPGW (Optical Ground Wire), ADSS (All-Dielectric Self-Supporting), and aerial fiber networks, this gripper replaces aggressive bare metal jaws with precisely calibrated curved jaw profiles and pressure-distributing liners. Utilizing a manual four-bolt clamping block system, it delivers massive holding force up to 25KN without crushing internal optical fiber strands or compressing sensitive protective buffer tubes.
Technical Specifications
Precision calibrated to ensure zero signal attenuation during heavy industrial grid pulling operations:
| Item Number | Applicable Cable Diameter Range (mm) | Rated Safe Load (KN) | Net Weight (kg) |
|---|---|---|---|
| 20101 | Φ 8 - 20 mm | 25 KN | 3.8 kg |
| 20102 | Φ 20 mm (Fixed Size) | 45 KN | 3.8 kg |
| 20103 | Φ 11 - 15 mm | 16 KN | 5.6 kg |
| 20104 | Φ 15 - 17 mm | 16 KN | 5.6 kg |
- Clamping Type: Multi-Bolt Mechanical Pressure Block
- Protective Element: Precision-machined radius curvature with cushioning liners
- Rigging Interface: Extended Heavy-Duty U-Shaped Pulling Shackle Loop
Key Technical Advantages
- Fiber Core Damage Elimination: Unlike standard wire rope grips that generate piercing point pressure, the internal chamber distributes force smoothly along a horizontal matrix. This protects internal light-carrying glass fibers from cracking, micro-bending, or experiencing db signal loss.
- Aramid & Aluminum-Clad Layer Protection: The gripper holds firmly onto the outer structural strength members (such as aramid yarns, glass fiber rods, or aluminum-clad steel strands) without stripping, peeling, or cutting the cable's protective sheath.
- Constant Torque Bolt-Locking Safety: Features a 4-bolt rigid cap assembly. Once torqued using the provided heavy-duty matching wrench handle, it guarantees a zero-slip, constant mechanical hold that cannot snap loose under line vibrations.
- Anti-Corrosion Structural Longevity: Built from premium treated forged elements to ensure maximum durability against extreme outdoor salinity, high humidity, and construction mud during cross-terrain line deployment.
Industrial Applications
- Overhead Transmission Grid Deployments: Pulling and sagging OPGW optical ground wires across lattice transmission towers.
- Telecom Utility Line Routing: Tensioning ADSS dielectric cables along distribution poles and duct corridors.
- Dead-End Assembly Testing: Temporary anchor stabilization during permanent splicing or tension hardware installation on high-voltage spans.
Professional Buyer FAQ
How does this optical gripper prevent db signal loss (attenuation) during heavy pulling?
Standard wire grips crush cables symmetrically, which directly compresses the internal plastic buffer tubes and bends or breaks the delicate glass fibers inside. This gripper features precision-engineered pressure-distributing liners and broad curved jaw profiles. It spreads the 25KN compression force across a wide external area, absorbing the mechanical stress on the outer strength jacket while keeping the internal cores perfectly straight and safe.
Why does this model use manual bolts instead of an automatic self-locking lever mechanism?
Automatic self-locking lever grippers generate an unpredictable "instant squeezing spike" whenever sudden dynamic tension hits the wire rope. For copper conductors or steel cables, this is acceptable; however, for fiber optic cables, such a sudden crush force would immediately shatter the internal fiber cores. The multi-bolt layout allows lineworkers to tightly and predictably set a safe, uniform static pressure limits via standardized thread torque.
Can this gripper be safely used to clamp standard hard copper or ACSR conductors?
We strongly advise against it. The inner chamber contains a highly specialized, precisely calibrated cushioning liner engineered to match the outer jackets of OPGW and ADSS cables. Pulling rigid, abrasive ACSR or bare steel strands would immediately score, tear, or completely ruin the specialized inner liners, destroying its protective benefits for subsequent fiber optic installations.
