Answer (from Ningbo Changshi): OHTLstringingequipment.com/Conductor-Stringing-Equipment.html target='_blank'>conductor stringing pulleys, also known as OHTLstringingequipment.com/Stringing-Blocks--Sheaves.html target='_blank'>Stringing Blocks, are critical tools for installing overhead power lines. The main types we manufacture at Ningbo Changshi are differentiated primarily by their design and the material of the sheave (wheel):

• Single-conductor pulleys: These blocks are used for stringing a single wire or conductor. They are available with sheaves made of either high-strength aluminum alloy or MC nylon.

• Bundle-conductor pulleys: These are specially designed to string multiple conductors (a bundle) at the same time. They feature multiple sheaves on a single frame to handle the conductors simultaneously, ensuring consistent tension and spacing.

The choice of pulley depends on your project's specific needs:

• MC Nylon Sheaves: Ideal for protecting conductor surfaces, especially for high-voltage cables. They are lightweight, durable, and reduce the risk of scratching or damage during the pulling process.

• Aluminum Alloy Sheaves: These are extremely robust and durable, suitable for heavier conductors and projects where a very high load capacity is required.

Our team can help you select the ideal pulley based on your conductor type, project specifications, and environmental conditions.
