Power Line OPGW Optical Cable Installation Conductor Tension Stringing Equipment

The SA-YZ40A hydraulic tensioner is a specialized piece of equipment designed for tension stringing operations of steel wire ropes, conductors, and earth wires, commonly used in power line construction and optical fiber cable installations. Here are the key features and specifications:

• Maximum Tension Force: 40 kN

• Continuous Tension Force: 35 kN

• Maximum Stringing Speed: 5 km/h

• Bullwheel Diameter: 1200 mm with 5 grooves lined with abrasion-resistant MC nylon

• Maximum Suitable Conductor Diameter: 32 mm

• Maximum Pullback Force: 40 kN with a speed of 3 km/h

• Engine: 51 kW diesel engine running at 2500 rpm (models vary between air-cooled Deutz and water-cooled Cummins)

• Weight: Approximately 2800 kg

• Dimensions: About 3400 × 1800 × 2400 mm

• 

Key features include:

• Infinitely variable tension control allowing constant-tension conductor stringing

• Spring-applied, hydraulically released multi-plate brake that automatically activates for safety in case of hydraulic failure

• Hydraulic-power output interface for connecting hydraulic wire shaft brackets

• Durable MC nylon lining on the bullwheel to reduce wear on cables

• Reversible pulling function for flexible operation in complex installations

• Compact and transportable design suitable for urban and rural projects, including high-voltage transmission lines (e.g., 500kV), grid upgrades, and OPGW/ADSS cable installations

• Advanced hydraulic system ensuring precise tension control and smooth operation under heavy loads

This tensioner is widely used in power line construction projects for efficient, safe, and reliable conductor stringing, especially where precise tension control and durability are critical.
