Product Description
The SKDS series Dual Cam Earth Wire Gripper is a high-grade, heavy-duty mechanical tensioning tool specifically engineered for permanent anchoring and pulling of overhead ground wires (OHGW) and GJ steel strands. Featuring an innovative mechanism of two opposing curved wedge elements (cams) within a sturdy housing, this gripper delivers a self-amplifying clamping force. As line tension increases, it secures the wire proportionally, ensuring zero slippage and superior anti-vibration performance without crushing delicate aluminum-clad or galvanized steel strands.
Precision forged to support extreme tensile loads, each model satisfies rigorous power grid construction standards:
| Item Number | Model | Applicable Conductor Type | Max Applicable OD (mm) | Rated Safe Load (KN) | Net Weight (kg) |
|---|---|---|---|---|---|
| 14221 | SKDS-1 | GJ Steel Strand / Ground Wire | Φ11 - Φ13 mm | 10 KN | 2.6 kg |
| 14222 | SKDS-2 | GJ Steel Strand / Ground Wire | Φ11 - Φ14 mm | 20 KN | 3.5 kg |
| 14223 | SKDS-3 | GJ Steel Strand / Ground Wire | Φ12 - Φ15 mm | 30 KN | 4.1 kg |
- Housing Material: Heavy-Duty Structural Alloy Steel
- Clamping Element: Opposing Dual-Cam Curved Wedges
- Compatible Wire Range: Optimized for GJ25 to GJ120 Steel Strands
- Self-Amplifying Dual Cam Design: Utilizes two opposing curved wedge elements that instantly lock onto the wire rope. The greater the towing tension, the tighter the inner cams squeeze, establishing a fail-safe mechanical lock.
- Strand Protection Geometry: Unlike traditional bolted clamps that concentrate stress and deform wires, the precision-machined curved profile of the cams distributes pressure evenly, preventing localized strand crushing or fracturing.
- Vibration-Resistant Grip: The unique dual-eccentric action provides constant spring-loaded and friction-induced stability, ensuring the clamp does not shake loose during high-altitude windy conditions.
- Robust Weatherproof Body: Constructed from premium hardened steel alloys with industrial anti-corrosion coating to prevent seizure or rusting in coastal and high-humidity utility corridors.
- Overhead Ground Wire (OHGW) Installation: Tensioning and dead-ending tower lightning protection lines.
- OPGW Optical Cable Maintenance: Securely holding the outer steel armor wire strands during line splicing.
- Substation Grid Construction: Anchoring heavy-duty galvanized steel earth wire networks.
No. The SKDS series is heavily optimized with aggressive curved cams intended for high-tensile GJ steel strands and overhead ground wires. Using it on softer metals like bare copper or AAAC will cause severe deformation or shear damage to the line.
Parallel jaw grippers rely on single-plane leverage, whereas the dual opposing cams wedge the wire from two reverse focal points simultaneously. This delivers a significantly higher friction-to-tension ratio, meaning it requires less initial pulling force to achieve a completely slip-free lock.
Selection should be based on your project's maximum tension requirements and cable outer diameter. For instance, if you are tensioning heavy-duty ground wires up to Φ15mm with pulling targets near 30KN, the heavy-duty SKDS-3 (4.1kg) is required.
