What specialized equipment is needed to construct and maintain a 400kV line?
2025-08-13The construction of a 400kV line is a massive undertaking that requires heavy-duty, high-capacity equipment. Our product line is designed specifically to meet these demands:
-
High-Capacity Stringing Equipment: The sheer weight and tension of 400kV conductors necessitate our most powerful hydraulic puller and OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner machines. These machines are engineered to handle the massive loads and maintain the precise tension required to ensure the correct sag and clearance. For these lines, bundled conductors are often used, which requires specialized OHTLstringingequipment.com/Stringing-Blocks--Sheaves.html target='_blank'>Stringing Blocks with multiple sheaves and high-capacity hydraulic machines capable of stringing multiple conductors simultaneously.
-
Overhead Tools and Accessories: We provide a full range of heavy-duty tools, including robust Conductor Grips, Swivel joints, and hoisting tackles that are designed to withstand the extreme forces involved in EHV line construction.
-
Lifting and Erection Tools: Our gin poles and winches are used for the erection of the massive transmission towers and the installation of heavy components.
