Hydraulic Brake Tensioner Winch For Overhead Power Transmission Lines Stringing

A Hydraulic Brake Tensioner Winch for Overhead Power Transmission Lines and OPGW Stringing is a specialized winch designed to provide controlled pulling and tensioning of overhead conductors and Optical Ground Wire (OPGW) cables during stringing operations.

Key Features:

• Hydraulic Brake System: Provides precise control over tension and braking, ensuring smooth and safe conductor payout without sudden jerks or overruns.

• Tensioning Capability: Designed to maintain constant tension on conductors or OPGW cables, critical for proper sag and alignment during installation.

• Power Source: Typically powered by diesel or petrol engines driving a hydraulic circuit, offering reliable and portable operation in field conditions.

• Load Capacity: Common models have pulling forces ranging from around 5 tons (50 kN) up to higher capacities depending on the application.

• Portability: Many models are compact and lightweight enough to be towed by small vehicles and positioned easily by one or two operators.

• Additional Features:

  • Variable displacement hydraulic pumps for smooth speed and force control.

  • Secondary capstans for fine load positioning.

  • Ground anchors or vehicle anchoring for operational stability.

  • 

Typical Applications:

• Stringing and tensioning of overhead transmission line conductors and OPGW cables.

• Tower erection and conductor sagging operations.

• Cable pulling in power line construction and maintenance.

Example Models and Specs:

These hydraulic brake tensioner winches are essential for safe, efficient, and precise conductor installation in overhead power transmission projects, especially when handling sensitive cables like OPGW that require careful tension control.
