In OPGW (Optical Ground Wire) stringing work, a supporting roller is a device used to guide and support the OPGW cable as it is being installed on the overhead transmission line. The primary function of the supporting roller is to reduce the friction and ensure smooth movement of the cable during the stringing process.
These rollers are typically placed at strategic points along the line, such as near transmission towers or along the span between towers, to ensure the cable is correctly positioned and tensioned during installationEngineered for Field ToughnessManufactured with a high-strength galvanized steel frame, the OPGW Hanging Pulley stands up to harsh outdoor conditions. It resists corrosion and deformation, making it ideal for use in rugged, exposed environments. Whether it's extreme heat, cold, or moisture, this pulley keeps cable installations smooth and reliable.
Adaptable Sheave OptionsThis pulley offers the flexibility of nylon or aluminum sheaves, available in diameters from 90 mm to 120 mm. Its uniquely shaped U or V grooves provide optimal protection and guidance for OPGW, ADSS, and other overhead fiber cables. Choose the sheave type and size that best fits your installation needs.
User-Centric Operation and MountingWith a manual, voltage-free operation and ergonomic handle design, the pulley ensures user comfort during prolonged use. The hook or bolt mounting mechanism enables fast and secure attachment to transmission towers, streamlining the installation process. Durable bearings and a smooth wheel surface minimize cable wear.
FAQ's of Opgw Hanging Pulley:
Q: How is the OPGW Hanging Pulley typically installed on transmission towers?
A: The pulley can be mounted using a hook or bolt, allowing it to attach securely to most tower structures. This mounting flexibility ensures stability during cable stringing or trolleying operations.
Q: What cable types and sheave groove shapes are supported by this hanging pulley?
A: The OPGW Hanging Pulley is suitable for OPGW, ADSS, and other overhead optical fiber cables. It is available with U or V-shaped grooves in the sheave to match different cable profiles and ensure optimal cable protection.
Q: Where is the ideal environment to operate this pulley system?
A: Engineered for outdoor use, the pulley is resistant to extreme temperatures (from -40C to +70C) and rugged environmental conditions, making it perfect for field installation of overhead power and communication cables.
Q: In what way do the pulley's material and finish enhance its durability?
A: Constructed with high-strength galvanized steel and coated to prevent rusting, the frame delivers excellent tensile strength and corrosion resistance. The sheave, made of nylon or aluminum, is wear-resistant for long-term use.
Q: What are the benefits of using an OPGW Hanging Pulley during cable installation?
A: This pulley facilitates smooth and controlled handling of overhead cables, reduces wear on the cable jacket, and enhances the efficiency and safety of installation. Its robust design and smooth rotation ensure a reliable operation.
Q: How much load can the pulley accommodate during field use?
A: Depending on the chosen model, the pulley can support loads up to 1-2 tons, meeting the lifting requirements for standard OPGW cable installations.
