Product characteristics and application
Upgraded Durability and Corrosion Resistance: The hot-dip galvanized surface is treated with passivation and sealing, providing dual enhancement of coating adhesion and corrosion resistance. This effectively prevents rust and damage caused by coastal salt spray, mining sulfides, and industrial acid rain. The main and auxiliary materials adopt the same-grade anti-corrosion process, eliminating corrosion shortboards. The designed service life is significantly longer than that of conventional poles and towers, greatly reducing the frequency of mid-term renovation and local repairs, and ultimately lowering the full-life cycle operation and maintenance costs of transmission lines.
Structural Optimization: Adopts a symmetrical M-shaped truss structure with a clear force transmission path, which can efficiently disperse wind loads, ice accretion and line tension. It features excellent wind and seismic resistance, small tower deflection and high stability. Under the same load conditions, its self-weight is reduced by 10%–15% compared with conventional angle steel towers, greatly relieving foundation bearing pressure and lowering civil construction costs.
Modular Assembly: Adopts standardized prefabrication and bolted assembly design. Components feature unified specifications and strong interchangeability, with trial assembly and inspection completed before delivery. No on-site welding is required, enabling convenient installation and short construction periods. It is adaptable to various sites such as mountainous areas, suburban zones and farmlands, with more flexible transportation and hoisting.
Wide Scene Adaptability: Tower height, cross arms and foundation types can be customized according to project voltage levels, load requirements and topographic conditions. It accommodates different working conditions including straight-line, angle and terminal towers. It not only meets conventional power transmission erection needs but also adapts to diversified scenarios such as distributed photovoltaic power stations and communication base stations.
Full-Life Cycle Service: Provides one-stop services covering scheme design, production and manufacturing, logistics distribution, on-site installation guidance and later operation and maintenance. Complete qualifications and a sound quality inspection process are available to fully ensure efficient project acceptance and stable operation.
