Lattice Aluminum Alloy Emergency Restoration Tower For Power Lines Restoration

The Lattice Type Aluminum Alloy Emergency Restoration Tower is a specialized lightweight, corrosion-resistant tower designed primarily for rapid deployment in emergency power line restoration and related applications.

Key Characteristics:

• Material: Made from high-strength aluminum alloy, commonly 6005 or 6082-T6, which offers excellent strength-to-weight ratio, corrosion resistance, and durability. The aluminum alloy is often aged with T6 heat treatment for enhanced mechanical properties.

• Structure: Typically a lattice framework composed of multiple aluminum alloy columns and circular crossbars forming triangular or portal-framed sections. Sections are modular, usually 3 meters or 6 meters in length, bolted together without welding to facilitate quick assembly and disassembly.

• Design Features:

  • Single-leg or portal-framed structures depending on the model; portal-framed types are common for 110kV and 220kV restoration towers.

  • The lattice design is optimized via CAD/CAE and finite element analysis to ensure strength, stability, and compliance with Eurocodes or other structural standards.

  • The tower is designed to withstand harsh environmental conditions, including wind speeds over 40 m/s and icing loads, making it suitable for high-altitude or severe weather area.

  • Components are CNC machined for precision and assembled with bolts, eliminating welding to reduce weight and improve maintainability.

• Dimensions & Load:

  • Heights vary widely, with some models reaching up to 45 meters or more.

  • Cross-section widths typically range from 600 mm to 1200 mm depending on the tower type and application.

  • Weight per section is relatively low (e.g., 55-66 kg per 3m section), facilitating transport and rapid erection.

• Applications:

  • Emergency restoration of power lines after outages or damage.

  • Temporary or permanent support for transmission lines, communication antennas, or monitoring equipment.

  • Suitable for use in rugged or remote locations due to its lightweight and corrosion-resistant properties.

• Additional Features:

  • Painted with electrostatic coatings in aviation safety colors (e.g., red RAL3020 and white RAL9010) for visibility and corrosion protection.

  • Compatible with accessories like crossing structures and lifters for installation support.

  • Certified for structural safety and compliance with relevant standards (Eurocode, AS standards, etc.).
