2x35KN Hydraulic Cable Tensioner 4000KG Hydraulic Puller Tensioner for Overhead Conductor Stringing

SA-YZ70 Hydraulic Cable Tensioner for Overhead Conductor Stringing

The SA-YZ70 is a hydraulic cable tensioner for stringing conductors and ground wires on overhead transmission lines. Infinitely variable tension control allows constant-tension stringing of one or two bundled conductors, and two hydraulic power output interfaces connect hydraulic conductor reel stands for a complete tension-stringing setup.

Technical Specifications

Main Components

Applications

• Constant-tension stringing of conductor and ground wire on overhead transmission lines
• Single or double bundled conductor stringing projects
• OPGW and conductor tension stringing for lines up to 1000KV construction
• Transmission line projects requiring a complete tension-stringing equipment set

Why Choose the Suntech SA-YZ70

• Infinitely variable tension control: delivers constant-tension stringing so conductor sag and alignment stay consistent along the run.
• Dual reel-stand interface: two hydraulic power output interfaces connect hydraulic conductor reel stands for a coordinated two-bundle pull.
• Fail-safe braking: a spring-applied, hydraulically released multi-plate brake acts automatically on hydraulic failure.
• Wear-resistant bullwheel: MC nylon lining segments protect the conductor and extend bullwheel life.
• Trusted components: Beinei Deutz air-cooled diesel engine with Rexroth hydraulics, RR/Rexroth reducer and AKG radiator.
• Factory experience: built by Suntech Power Tools, a Ningbo supplier of complete stringing equipment and tools for transmission line construction, exported to over 50 countries under ISO 9001.

FAQ

Q: Can it string two conductors at once?
A: Yes. It handles 2x35KN maximum tension for two bundled conductors, or 1x70KN for a single conductor.

Q: How is tension controlled?
A: Tension is infinitely variable, enabling constant-tension conductor stringing throughout the pull.

Q: What conductor sizes fit?
A: The Φ1200mm bullwheel with 2x5 grooves takes conductor up to Φ32mm.
