OPGW installation requires specialized equipment to protect the delicate optical fibers within the cable. While the basic process is similar to stringing standard conductors, key differences include:

• Specialized Grips: OPGW requires non-damaging, soft-lined grips (come-along clamps) that distribute pressure evenly to avoid crushing the fibers.

• Grooved Sheaves: OHTLstringingequipment.com/Stringing-Blocks--Sheaves.html target='_blank'>Stringing Blocks (pulleys) must have a groove profile specifically designed for the diameter of the OPGW cable and be made of materials like nylon or polyurethane to prevent abrasion.

• Controlled Tension: A hydraulic puller-OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner with highly sensitive controls is essential. It must maintain a smooth, constant tension to avoid sudden jerks or excessive sag that could damage the optical fibers.

• Swivels: High-quality, anti-twisting Swivels are crucial to prevent the OPGW from rotating during the pulling operation, which can cause internal fiber damage.

At Ningbo Changshi, we offer complete OPGW stringing solutions, including specialized puller-Tensioners, nylon-sheave Stringing Blocks, and appropriate swivels designed to ensure the integrity of your fiber optic network.
