Product Description

2*40kN Hydraulic Cable Tensioner for Overhead Line Stringing | Dual-Groove Conductor Tension Machine

The 2*40kN Hydraulic Cable Tensioner is a high-performance tension control device designed for overhead transmission line construction and conductor stringing projects. With two independent tensioning wheels providing a combined tension force of 40kN per groove, this machine ensures smooth, stable, and safe installation of ACSR, AAAC, OPGW, and ground wires. It is widely used in 110kV-220kV transmission lines and medium-span conductor stringing operations.

What Is a Hydraulic Cable Tensioner?

A hydraulic cable tensioner provides constant and controlled tension during conductor or OPGW installation. Its purpose is to prevent conductor sagging, maintain uniform tension, protect conductors from damage, and improve overall stringing safety and efficiency. The 2*40kN model is ideal for dual-conductor or single large-size conductor stringing.

Key Features

Dual Tensioning Grooves (2 * 40kN): Ensures stable conductor deployment, suitable for bundled conductors or single large-size conductors
Automatic Hydraulic Control: Constant tension regulation, smooth speed adjustment, overload automatic protection
Wear-Resistant Bullwheel Liners: Aluminum or MC nylon lining for maximum protection of conductor surface
Real-Time Digital Monitoring: Displays tension, speed, and conductor payout length with optional data recorder
Robust Build for Field Work: Reliable performance in mountains, long spans, river crossings, designed for long hours of continuous operation

Advantages

Stable & consistent tension, ideal for high-precision stringing
Highly durable hydraulic system with low maintenance cost
Reduced conductor wear thanks to optimized groove design
Designed for high-voltage line contractors & EPC projects
Supports single or bundled conductor operations

Applications

The 2*40kN hydraulic tensioner is commonly used for overhead transmission line construction (110kV-220kV), ACSR/AAAC conductor tension stringing, OPGW and ground wire installation, mountain, river crossing, and medium-span projects, and dual-conductor operations.
