The construction of a 220 kV line is a large-scale engineering project that demands heavy-duty and highly reliable equipment. Ningbo Changshi specializes in manufacturing and supplying this exact machinery. Key equipment includes:

• High-Capacity Pullers and OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners: For bundled conductors, you need specialized hydraulic puller and OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner machines with higher capacities and multi-drum designs to handle the multiple conductors per phase simultaneously and maintain the precise tension required.

• Heavy-Duty Stringing Blocks: Our Stringing Blocks are designed with larger grooves and robust frames to support the greater weight and diameter of the bundled conductors. These blocks are crucial for protecting the expensive conductors from damage during installation.

• Anti-Twist Steel Wire Ropes: Due to the long spans and heavy loads, high-strength and anti-twist ropes are necessary to guide the conductors smoothly and safely through the blocks.

• Tower Erection Tools: For the large steel lattice towers, specialized gin poles, winches, and rigging equipment are used to lift and assemble the tower sections.

Our complete range of Overhead Transmission line equipment is engineered to meet the stringent demands of 220 kV construction, ensuring a safe and efficient stringing process.
