High Voltage Steel Pipe Tower

Qingdao Anbang New Energy High-Voltage Steel Tubular Tower is a core transmission support equipment integrating "design-manufacturing-installation-service". Specifically engineered for 10kV-1000kV high-voltage, ultra-high-voltage (UHV), and extra-high-voltage power transmission lines, it covers multiple structural types including lattice type, single-column tapered type, and narrow-base combined type.

As a "Top 10 Steel Pipe Pole Enterprise of 2022", the company relies on 20 core patents, an annual production capacity of 50,000 tons, and certifications in national/industry standards such as GB/T 2694 and GB 50205.

The product adopts Q355B/Q420/Q460 grade high-strength steel, featuring hot-dip galvanizing anti-corrosion, patented welding technology, and reinforced structural design.

It can operate stably in complex scenarios such as typhoon-prone areas, heavy icing regions, and urban restricted corridors, providing safe and reliable power transmission solutions for the power, communications, industrial and other fields, and has successfully served hundreds of customers worldwide. Both received high praise from the clients.

Core Advantages

Patented Empowerment for Stable Structure

Exclusive ownership of core patents including "Reinforced Structure for Power Tower Steel Components" and "Special Welding Fixture for Angle Steel Tower Base". Through triangular stable support design and hole-free reinforcement technology, the bearing capacity is enhanced without damaging the body strength.

The welding fixture is adaptable to positioning of various specifications of steel plates; welds undergo non-destructive testing, ensuring high joint stiffness and minimal eccentricity. Its wind vibration and anti-icing capabilities are significantly superior to traditional products.

High Strength & Corrosion Resistance for Longer Service Life

Main materials are low-alloy high-strength steel. The thickness of hot-dip galvanized coating is not less than 85μm, and the closed steel pipe structure effectively prevents water and dust accumulation, achieving an anti-corrosion service life of over 30 years.

Strictly controlled rod bending degree (≤2‰ of length) and ovality (≤2D/1000) ensure adaptability to harsh environments such as high salt spray in coastal areas and high wind and sand in northwest China, with daily maintenance workload only 1/3 of that of traditional iron towers.

Scenario Adaptability with Optimal Floor Space

Multiple structural options available (narrow-base combined type, single-column tapered type). The single-tube tower only requires a circular foundation, reducing floor space by more than 60% compared with angle steel towers, perfectly suitable for urban power grid transformation, industrial parks and other corridor-restricted scenarios.

The streamlined steel pipe cross-section has a low wind resistance coefficient, reducing wind load by 30% in typhoon-prone areas and long-span sections (river/canyon crossings). For UHV scenarios, the tower height can reach 130m and tower weight 260 tons, meeting the requirements of double-circuit power transmission.

Full-Chain Service for Efficient Delivery

Provides turnkey services of "customized design-factory prefabrication-on-site assembly". The 50,000㎡ production base guarantees rapid mass production.

Adopting refined construction schemes such as high-strength nylon rope hoisting, the installation cycle is 20% shorter than the industry average. Full-process technical support including foundation design and component adaptation is provided.

Application Scenarios

Power Transmission Field: 110kV-1000kV UHV/extra-high-voltage power transmission lines and substation structures, especially suitable for cross-regional energy transmission projects in Inner Mongolia, Guangxi and other regions.

Urban & Industrial Scenarios: Urban power grid upgrading, industrial park power distribution, and 10kV power transmission projects for charging and swapping stations. The narrow-base design reduces land acquisition costs and adapts to dense building complex environments.

Complex Climates & Terrains: Typhoon-prone coastal areas, heavy icing regions in southwest China, high wind speed areas in northwest Gobi, as well as long-span transmission sections such as river/canyon crossings.

Multi-Industry Adaptation: Communication base station support, radio and television towers, and special power transmission facilities for the military. Customizable tower structures of various specifications are available to meet specific needs.

Frequently Asked Questions (FAQ)

1. Is the cost of high-voltage steel tubular towers higher than that of traditional angle steel towers?

The initial manufacturing cost is slightly higher, but the comprehensive cost is more advantageous! The steel tubular tower is lighter (30% weight reduction under the same load), reducing foundation construction costs by 20%-40%.

With an anti-corrosion service life of up to 30 years, the later maintenance cost is only 1/3 of that of traditional angle steel towers. Moreover, its compact floor space significantly reduces land acquisition costs in urban areas, resulting in much higher cost-effectiveness in long-term use.

2. How to ensure the stability and safety of the tower in UHV long-span projects?

UHV long-span towers adopt lattice-type reinforced structures, with main materials made of Q460 high-strength steel. The force distribution is optimized through 3D finite element analysis, and joints are double-fixed by intersecting line welding and flange connection, with eccentricity ≤3mm. Before delivery, 1:10 scale model wind tunnel tests and load limit tests are conducted.

After on-site installation, ultrasonic flaw detection and overall verticality inspection are performed to ensure compliance with 1000kV UHV power transmission load requirements. The product has been operating stably in multiple cross-river UHV projects.

3. How to perform daily maintenance and what is the maintenance cycle?

Maintenance is simple and convenient! It is recommended to conduct regular inspections once a year: check the tightness of bolts, the sensitivity of fall arrest rails (if equipped), and clear obstacles around the tower.

Anti-corrosion coating touch-up should be carried out every 5-8 years according to environmental conditions. The closed steel pipe structure prevents internal corrosion, eliminating the need for frequent overhauls and significantly reducing maintenance workload.

4. Is customized design supported and what is the delivery cycle?

Full-scenario customization is available! The tower structure can be tailor-made according to voltage level, load requirements, terrain and climate, floor space restrictions and other parameters.

The delivery cycle for standard products is 15-30 days; for large UHV towers or customized products, the cycle can be negotiated based on project scale. The company's annual production capacity of 50,000 tons ensures rapid mass production and delivery.
