Product Description

At first, we just want to create a stringing block that can reduce the damage of the wire cable during the operation, but during the testing we found this structure can be a specialized piece of equipment designed for the installation of Optical Ground Wires (OPGW) on overhead power lines, so the MARSHINE OPGW Fiber Optic Fiber Stringing Blocks is born. This MARSHINE OPGW stringing block plays a critical role in ensuring the safe and efficient deployment of OPGW cables, which combine traditional ground wire functions with optical fiber communication capabilities.

Product Application

The MARSHINE OPGW stringing block is a specialized tool used to install and maintain fiber optic ground wires, which are composite cables that combine optical fiber with traditional ground wires used in transmission lines. Key applications include:

Stringing new OPGW cables

Initial installation: The block facilitates the initial installation of OPGW cables on new or existing transmission towers. It helps guide the cable smoothly onto the tower, reducing friction and preventing damage.

Tension control: By providing precise tension control, the block ensures that the OPGW cable is installed with the correct tension, avoiding problems such as excessive sag or overstressing.

Replacing existing OPGW cables

Safe removal: When replacing old OPGW cables, the block can be used to guide the old cable safely off the tower, minimizing the risk of damage to the tower or surrounding equipment.

New cable installation: After removing the old cable, the block is used again to install the new OPGW cable, ensuring a smooth transition.

Maintenance and Repair

Inspection: During routine inspections, the trolley can be used to temporarily lower the section of the OPGW cable for closer inspection or testing.

Damage Repair: If a section of the OPGW cable is damaged, the MARSHINE OPGW stringing block can help isolate the damaged section and install a new section without affecting the rest of the line.

Emergency Repair

Quick Response: In emergency situations such as storm damage or unexpected breaks, the block can quickly and safely repair the OPGW cable, restoring communications and power transmission as quickly as possible.

Upgrading Transmission Lines

Enhancing Existing Lines: For lines with existing OPGW, this stringing block can be used to upgrade to newer, more advanced OPGW cables with higher capacity or better performance.

Training and Simulations

Operator Training: This MARSHINE OPGW stringing block can be used for training exercises to teach new operators how to properly install and maintain OPGW cables.
