916mm Large Diameter Conductor Pulley for Ultra High Voltage Construction

916mm Large Diameter Conductor Pulley: The Hardcore Performer for Ultra High Voltage Construction
In today's booming ultra-high voltage transmission projects, the 916mm large-diameter conductor pulley, with its ultra-high standard performance, has become an indispensable core equipment in overhead line construction, safeguarding the construction of power transmission channels.
Extra-Large Specifications, Adapting to High-Level Engineering Requirements
The pulley dimensions are φ916×φ800×110mm, specifically designed for large cross-section conductors of LGJ720 and below. The single-wheel rated load can reach 50kN, and multi-wheel models can carry loads exceeding 80kN.
Compatible with various conductor types such as single-bundle, double-bundle, and four-bundle conductors, allowing smooth passage of compression sleeves, rotating connectors, and other accessories, meeting the stringent construction requirements of ultra-high voltage DC and AC projects.
Suitable for complex scenarios such as power transmission from "desert and Gobi" bases and offshore wind power supporting lines, demonstrating stable performance in long-distance, high-load stringing operations.
High-Quality Materials, Balancing Safety and Durability
The pulley body is made of high-strength MC nylon material, which has self-lubricating properties, resulting in minimal wear and no friction sparks, effectively protecting the conductor from damage and extending its service life.
The frame is made of galvanized steel, reinforced by folding edge technology, resistant to falls and deformation, and can withstand harsh environments such as wind, rain, and high salt spray during outdoor operations.
Stable performance in low-temperature environments, suitable for special working conditions such as high altitude and large temperature differences, requiring less frequent maintenance and reducing overall construction costs.
Efficient and Labor-Saving, Improving Core Construction Efficiency
The pulley has built-in ball bearings, resulting in low traction resistance, making conductor laying, pulling, and tensioning operations smoother and significantly reducing labor input.
The scientific structural design ensures even force distribution, accurately guiding the conductor direction in complex terrains such as mountains and rivers, avoiding jamming and slipping risks.
Compared with traditional tools, construction efficiency is significantly improved, contributing to the rapid progress of ultra-high voltage projects and meeting the construction needs of over 28,000 kilometers of ultra-high voltage lines during the "15th Five-Year Plan" period.
