Unlike conventional stringing rollers designed for a single conductor, a double line cable replacing roller supports both the outgoing and incoming conductors simultaneously. This configuration enables crews to use the existing conductor as a guide while pulling in the replacement conductor, improving efficiency and reducing installation time.
What’s MARSHINE Double Line Cable Replacing Stringing Roller?
The MARSHINE MAR-026RBT2 Double Line Cable Replacing Stringing Roller is specifically engineered for this purpose. Featuring durable nylon rollers, a galvanized steel frame with nylon protection plates, a 2 KN working load, a 10 KN breaking load, and a lightweight 1.8 kg construction, it provides reliable performance for conductor replacement and maintenance work.
So What’s The Advantage Of It?
Designed Specifically for Conductor Replacement
The greatest advantage of the MARSHINE MAR-026RBT2 Double Line Cable Replacing Stringing Roller is that it is purpose-built for replacing existing overhead conductors. During a conductor replacement project:
The existing conductor remains in position.
The new conductor is connected to the old one.
Both conductors pass through the roller together.
The old conductor helps guide the new conductor along the original route.
This process reduces installation complexity and eliminates the need to completely restring the line from the beginning. By supporting two conductors simultaneously, the MAR-026RBT2 enables smoother and more efficient replacement operations.
Dual Roller Design Improves Cable Guidance
Unlike single-groove rollers, the MAR-026RBT2 incorporates a double-line guiding design. Each conductor follows its own dedicated path, providing several advantages:
Prevents conductors from crossing.
Maintains stable cable spacing.
Reduces conductor twisting.
Keeps both cables aligned throughout the pulling operation.
Better cable guidance results in smoother pulling and lowers the risk of conductor damage. This is especially beneficial when replacing conductors over long spans or through multiple support structures.
Nylon Rollers Protect the Conductor Surface
Protecting the conductor during installation is essential, particularly when working with aluminum conductors, ACSR conductors, or insulated cables. The MARSHINE MAR-026RBT2 Double Line Cable Replacing Stringing Roller uses high-quality nylon rollers, which provide a smooth contact surface that helps:
Reduce abrasion.
Minimize conductor scratches.
Lower friction during pulling.
Protect conductor strands.
Extend conductor service life.
Compared with steel rollers, nylon rollers offer gentler cable handling while still providing excellent wear resistance.
Galvanized Steel Frame Provides Excellent Durability
The frame is manufactured from galvanized steel, providing both mechanical strength and corrosion resistance. The galvanized finish offers several benefits:
Protection against rust.
Long service life in outdoor environments.
Reduced maintenance requirements.
Excellent resistance to rain and humidity.
Reliable performance in demanding construction conditions.
Whether used in rural transmission projects or coastal utility installations, the galvanized frame helps maintain long-term durability.
Nylon Protection Plates Reduce Cable Damage
An important feature of the MARSHINE MAR-026RBT2 Double Line Cable Replacing Stringing Roller is its integrated nylon protection plates. These protective components help prevent accidental contact between the conductor and the steel frame. Their benefits include:
Reduced insulation damage.
Lower risk of conductor abrasion.
Improved cable positioning.
Additional protection during directional changes.
Lightweight for Easy Installation
Weighing only 1.8 kg, the MAR-026RBT2 is extremely easy to transport and install. Its lightweight construction provides several practical advantages:
Easy carrying between work locations.
Faster installation on poles or cross-arms.
Reduced operator fatigue.
Improved efficiency during large projects.
Convenient storage and transportation.
Field crews can quickly position multiple rollers without requiring lifting equipment.
