300–400 sqmm Aluminum Alloy Come-Along Clamp
Transmission Line Grip for ACSR & AAAC Conductors
The 300-400 sqmm Aluminum Alloy Come-Along Clamp is a heavy-duty transmission line stringing tool designed for securely gripping and pulling ACSR and AAAC conductors. Made from high-strength aluminum alloy, it offers a lightweight yet durable solution for conductor installation, reducing labor effort and ensuring safe, efficient line stringing operations.
Product Definition
A Come-Along Clamp is a mechanical gripping device used to hold, pull, or tension conductors during overhead line stringing. This model is optimized for ACSR and AAAC conductors sized 300-400 sqmm, featuring a durable aluminum alloy frame for corrosion resistance and safe, slip-resistant grip under high tension.
Key Features
- High-Strength Aluminum Alloy: Lightweight yet robust, resistant to corrosion and field wear.
- Adjustable Grip for 300-400 sqmm Conductors: Securely grips ACSR and AAAC conductors within the specified range without slipping or damaging the cable.
- Come-Along Pulling Mechanism: Allows controlled conductor tensioning, reducing manual effort and improving installation efficiency.
- Smooth Surface & Ergonomic Design: Minimizes conductor surface damage and ensures ease of handling by field technicians.
- Versatile Use: Works with single conductors, pilot ropes, or in combination with tensioners and pullers.
Advantages
- Lightweight & Easy to Operate: Aluminum alloy reduces weight without compromising strength.
- Safe & Reliable: Slip-resistant jaws and secure clamping design prevent accidents during line stringing.
- Compatible with Standard Transmission Line Tools: Can be used alongside tensioners, hydraulic pullers, and duct rods.
- High Durability: Designed to withstand harsh field conditions, including extreme weather and long-duration pulls.
- Precise Conductor Handling: Ensures consistent tension control and prevents conductor deformation.
Applications
- Pulling and tensioning ACSR / AAAC conductors during overhead line construction
- Medium- and high-voltage transmission line projects
- Tower-to-tower conductor stringing operations
- Use in combination with hydraulic pullers, tensioners, and duct rods
- Conductor installation in long-span, mountain, or complex terrain lines
