Eccentric Dual-Cam Come Along Clamp for Earth Wire Tensioning Applications
Posted by Paprsky Energy on 22nd Apr 2026
Introduction
In overhead line installation and maintenance, accurate wire tensioning is essential to ensure structural stability and operational safety. Tools used in these applications must provide secure gripping without damaging the conductor surface. The Eccentric Dual-Cam Come Along Clamp PS-SKDP Series is designed to deliver controlled gripping force and reliable performance under varying load conditions.
What is an Eccentric Dual-Cam Come Along Clamp?
An eccentric dual-cam come along clamp is a mechanical device used to grip and tension steel strands and earth wires during installation and maintenance of transmission and distribution lines. The clamp utilizes a dual-cam mechanism that increases clamping force as tensile load is applied.
This self-tightening action ensures stable engagement with the wire, allowing precise positioning and tension control without slippage. It is commonly used in applications where consistent holding strength and repeatable performance are required.
Product Information
The PS-SKDP Series is engineered for cable tower adjustment and wire tensioning operations in overhead line projects. It is compatible with a range of steel strand sizes, providing flexibility for different installation requirements.
The series includes multiple models:
- PS-SKDP-1: Suitable for GJ25–70 mm²
- PS-SKDP-2: Suitable for GJ50–70 mm²
- PS-SKDP-3: Suitable for GJ70–120 mm²
Each model is designed with an optimized jaw opening to ensure secure wire engagement while maintaining ease of installation and removal.
The dual-cam structure distributes clamping force across the contact area, reducing localized stress on the wire surface. This helps minimize deformation or damage during high-tension operations.
The clamp features a compact and robust construction, allowing reliable use in field environments, including elevated work conditions and confined installation spaces.

Industrial Applications
The PS-SKDP Series is widely used in power transmission and distribution projects for gripping and tensioning earth wires and steel strands. It plays a critical role in overhead line installation, ensuring proper alignment and controlled tension during setup.
In maintenance operations, the clamp is used for re-tensioning existing lines and replacing worn or damaged conductors. It is also applicable in infrastructure and construction projects where steel strands require temporary holding under load.
The tool is commonly used by utility contractors, electrical engineers, and field technicians involved in line construction and maintenance activities.
Performance Summary for Secure Wire Gripping and Tensioning Operations
The Eccentric Dual-Cam Come Along Clamp PS-SKDP Series provides consistent clamping force, stable load handling, and reliable wire engagement for tensioning applications. Its dual-cam mechanism ensures a secure grip under increasing load while minimizing stress on the conductor surface. The design supports safe and controlled operation across a range of overhead line installation and maintenance tasks.
