Overhead Power Transmission Distribution Lines Machine Tools Stringing Equipment

The SA-YZ30A Hydraulic Tensioner is a compact and efficient hydraulic tensioning machine designed for stringing single conductors, optical fiber composite overhead ground wire (OPGW), and all-dielectric self-supporting optic fiber cable (ADSS) on overhead power lines.

Key Specifications:

• Maximum Tension Force: 30 kN

• Continuous Tension Force: 25 kN

• Maximum Stringing Speed: 5 km/h

• Maximum Pullback Force: 20 kN

• Maximum Pullback Speed: 0.9 km/h

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

• Maximum Suitable Conductor Diameter: 32 mm

• Engine: Chinese top-brand water-cooled diesel engine (Model S195GM), 11 kW at 2200 rpm

• Electrical System: DC 12V

• Dimensions: 3560 × 1600 × 2220 mm

• Weight: Approximately 1700 kg

• 

Features:

• The bullwheel uses wear-resistant MC nylon lining segments to protect conductors and extend service life.

• Infinitely variable tension control enables constant tension stringing for safer and more efficient conductor installation.

• Equipped with a spring-applied, hydraulically released multi-plate brake that automatically engages in case of hydraulic failure to ensure safe operation.

• High-quality components including Italian RR reducer, AKG radiator, and WIKA hydraulic instruments enhance reliability.

• Suitable for a variety of electric conductors and ground wires, including OPGW and ADSS cables.

Applications:

The SA-YZ30A is ideal for medium-duty stringing operations on overhead transmission lines, especially for single conductors and optical fiber cables up to 32 mm in diameter. Its moderate tension capacity and compact size make it suitable for projects requiring mobility and precision tension control.

In summary, the SA-YZ30A Hydraulic Tensioner offers a reliable, safe, and precise solution for conductor stringing with a maximum tension of 30 kN, optimized for single conductor and optical cable installations on overhead power lines.
