The equipment used for three-phase transmission is designed to handle the increased complexity and demands of the system. While many of the tools are similar in principle, they are often larger, more powerful, and specifically configured for three-phase work. Key differences include:

• OHTLstringingequipment.com/Conductor-Stringing-Equipment.html target='_blank'>conductor stringing: Three-phase lines require the simultaneous or sequential stringing of three (or more, in the case of bundled conductors) individual conductors. Our Hydraulic Pullers and OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners are designed with multiple grooves and sufficient power to manage the installation of all phases at once, ensuring the correct sag and tension for each line.

• Sheaves and Rollers: The Stringing Blocks and rollers used on transmission towers are specifically designed to accommodate up to three conductors, often with specialized designs to prevent twisting or damage to the lines during the stringing process.

• Safety and Grounding Tools: Due to the higher voltages and multiple live phases, the safety and grounding equipment used on three-phase lines is highly specialized, ensuring that crews can safely work on or near energized lines.

Our comprehensive product range includes all the necessary machinery and tools to construct and maintain three-phase power lines, positioning Ningbo Changshi as an expert and trusted partner for any electrical project.
