On behalf of Ningbo Changshi Electric Power Machinery Manufacturing Limited, a prominent China manufacturer and global exporter specializing in comprehensive tools and equipment for power lines, substations, electrical construction, and maintenance, we are immensely proud to introduce our groundbreaking, industry-defining 200kN Hydraulic Conductor Tensioner. This unparalleled, exceptionally powerful, and technologically superior machine represents the definitive, ultimate solution, meticulously engineered to provide absolute precise and robust back tension during the stringing of the absolute heaviest conductors, critical large OPGW (Optical Ground Wire), and the most intricate, ultra-complex multi-bundle conductors (e.g., hexagonal, octagonal, or bespoke super-bundles) on Ultra-High Voltage (UHV) and Extra-High Voltage (EHV) overhead transmission lines (OHTL) across the globe. Equivalent to over 20 metric tons of tensioning force, it is truly indispensable for preventing conductors from touching the ground, absolutely safeguarding critical existing infrastructure, and impeccably preserving the conductor's integrity from any nicks, abrasions, or damage, thereby ensuring the long-term reliability, maximum capacity, and supreme operational safety of the world's most vital, high-demand grid infrastructure.

Our 200kN hydraulic tensioner offers an unprecedented level of control and immense, unyielding power for the most extreme, heavy-duty applications. It empowers operators to maintain exact tension values with absolute, unwavering precision, which is non-negotiable for safe and highly efficient stringing operations across the most formidable terrains, record-setting long spans, and with the largest, most complex conductor configurations imaginable. Its supremely robust construction, revolutionary dual-circuit hydraulic system, and intelligent, intuitive controls deliver exceptionally smooth, consistent, and impeccably reliable performance, making it the ultimate, indispensable asset for the most critical, largest-scale, and high-stakes power infrastructure mega-projects globally.

Product Features & Benefits:

The Ningbo Changshi 200kN Hydraulic Conductor Tensioner is meticulously engineered for the highest level of control, unparalleled conductor protection, and consistent, uncompromised performance in the most demanding UHV/EHV OHTL stringing operations.

• Unrivaled 200kN (Approx. 20.39 Ton) Tension Capacity: Provides an unparalleled level of precisely controlled back tension, making it the definitive solution for stringing the absolute heaviest single conductors, largest OPGW, and especially the most complex multi-bundle conductors (e.g., 6-bundle, 8-bundle, or even higher custom super-configurations). This guarantees optimal ground clearance, controlled sag, and meticulous handling of the most valuable and critical high-voltage assets.

• Revolutionary Dual Closed Hydraulic System with Advanced Control Logic: Features a state-of-the-art, dual closed hydraulic circuit (with independent, synchronized circuits for each bullwheel set) that enables infinitely variable tension adjustment and ultra-precise, synchronized speed control across the entire operational range. This advanced, redundant system incorporates sophisticated control logic to ensure exceptionally smooth, uniform, and consistent tension application, completely eliminating damaging surges, preventing over-tensioning, and critically protecting the conductor's surface integrity, even under extreme loads.

• Integrated Digital Control & Advanced Data Logging Suite with Telematics: Equipped with a highly accurate digital tension gauge (dynamometer), digital speedometer, and an advanced integrated data logger with GPS and telematics capabilities, providing continuous, real-time display and comprehensive recording of applied tension, stringing speed, distance, time, and critical operational parameters. This comprehensive feedback empowers operators to precisely monitor and maintain exact tension values, strictly adhering to the most stringent project specifications for quality assurance, paramount safety, and indisputable regulatory compliance, with remote monitoring and reporting for global operations.

• Massive, Multi-Pass Bullwheels with Ultra-Premium Composite Liners: Features exceptionally large-diameter, often multi-pass, bullwheels with highly durable, ultra-premium grade, ultra-wear-resistant, multi-groove composite liners (e.g., advanced polyurethane composites or specialized anti-abrasion materials, often interchangeable). This design ensures superior, consistent grip on the pulling rope or conductor, minimizes wear, and rigorously protects the conductor's surface integrity, even with immense loads and continuous, high-intensity, long-duration operation.

• Redundant, Quadruple Fail-Safe Braking System: Incorporates a robust, multi-stage automatic negative hydraulic brake system that engages instantly and securely when the machine operation ceases or in the event of any hydraulic pressure loss. This provides a critical, highly reliable, and quadruple-redundant fail-safe mechanism, immediately holding the conductor in place and significantly enhancing operational safety for personnel and high-value equipment.

• Independent, Heavy-Duty, Continuous-Duty Global-Class Power Source: Powered by a high-performance, industrial-grade diesel engine (e.g., leading global brands like Volvo Penta, Caterpillar, John Deere, or similar, Tier 4/Euro Stage V compliant or better), engineered for continuous operation under maximum load for extended periods. This offers complete independence from external power grids and ensures powerful, consistent, and long-duration performance even in the most remote and challenging construction sites globally, adhering to the strictest environmental standards.

• Ultimate Heavy-Duty & Unyielding Stable Construction: Built with an extraordinarily reinforced, high-tensile steel chassis and the absolute top-tier, heavy-duty components throughout, optimized for maximum stress resistance and torsional rigidity. This guarantees maximum long-term durability, exceptional resistance to continuous strenuous use, and unwavering stability in the harshest outdoor conditions and the extreme rigors of UHV/EHV OHTL stringing, ensuring unparalleled extended service life and minimal downtime.

• Ergonomic Operator Environment & Smart Interface: Features an intuitive, ergonomic, and fully-equipped, often weather-protected, control cabin/panel with clear, rugged displays and robust, joystick-controlled interfaces, allowing for precise management of tension, speed, and emergency stops. Advanced models include comprehensive diagnostic capabilities, predictive maintenance alerts, and potential for autonomous operation, enhancing operator efficiency, safety, and operational intelligence in the most critical stringing scenarios.

Product Applications:

Our 200kN Hydraulic Conductor Tensioner is ideally suited for:

• Global UHV (Ultra-High Voltage) & EHV (Extra-High Voltage) Transmission line stringing: The definitive, top-tier solution for efficient, controlled, and damage-free stringing of the absolute largest single conductors and the most complex multi-bundle conductors (e.g., quadruple, hexagonal, or custom super-bundles) for next-generation UHV and EHV lines worldwide, forming the backbone of future global power grids.

• Mega-Project River, Canyon, and International Border Crossings: Critical for managing tension over exceptionally long and critical spans where precise conductor control, monumental back tension, and uncompromising safety are paramount. This includes record-breaking crossings that redefine engineering possibilities.

• Advanced OPGW (Optical Ground Wire) & Shield Wire Installation: Essential for the controlled and protective installation of the heaviest OPGW cables and large shield wires, safeguarding communication and grid integrity across vast distances.

• Global Grid Backbone Modernization & Expansion Initiatives: Indispensable for the controlled removal of existing conductors and the safe, efficient installation of new, highest-capacity, or complex bundled conductors on vital existing transmission infrastructure as part of national and international grid upgrades, enabling future energy demands.

• Extreme Terrain & Remote Mega-Operations: Providing the necessary immense power, ultimate control, and rugged dependability for stringing operations in the most inaccessible mountainous, forested, desert, or challenging terrains globally, where other equipment simply cannot perform.

• Complex Substation Interconnections & High-Density Power Corridors: Ensuring precise and safe conductor management in constrained, high-value, or densely populated areas where errors are simply not an option.
