Substation steel frame product case
Project Background
In order to improve the reliability and stability of power supply, the Ugandan government decided to build a substation steel structure. The steel gantry tower and horizontal beam will be lattice-type to support 132kV equipment and conductors. To meet the requirements of high strength, durability and easy maintenance. To ensure construction quality and efficiency, all structural parts will be trial-installed in the factory.
Project Overview
● Project Name : Muzizi Steel Gantry Structures
● Construction location: LYANDA, KIBAALE DISTRICT
● General Contractor: Babcon Uganda Limited
● Construction Company: Babcon Uganda Limited
Design and Construction
Design Phase
1. Design standards: Strictly follow the relevant national and industry standards, including "Power Substation Design Code", "Steel Structure Design Code", "Building Seismic Design Code", etc.
2. Structural design:
● Main structure: Hot-rolled angle steel is used as main beams and columns to ensure the overall rigidity and stability of the structure.
● Secondary structure: Cold-bent angle steel is used as secondary beams and supports to enhance the stability of the overall structure.
● Connection method: High-strength bolts are used to connect the primary and secondary structures, and key nodes are reinforced.
3. Protection design: Considering the special environment of the substation, comprehensive lightning protection, fire protection and corrosion protection measures are designed. The external structure is sprayed with fire retardant paint, and the internal structure is coated with anti-corrosion coating.
Construction Phase
1. steel produced by well-known domestic manufacturers , and strictly inspect and accept it according to the standards to ensure the quality of the materials.
2. Steel is cut, drilled and assembled in the factory to ensure accurate dimensions and strong welding.
3. Factory trial installation:
● Pre-assembly: Pre-assemble the steel frame in the factory according to the design drawings, ensure that each component and node can be assembled correctly, and check the accuracy of size and connection.
● Adjustment and Verification: Identify and resolve potential issues through trial installation and make necessary adjustments to ensure seamless installation on site.
● Marking and disassembly: After the trial installation is completed, each component is numbered and marked, and disassembled and packaged in sequence to facilitate rapid assembly on site.
4. On-site installation:
● Foundation treatment: reinforce the foundation, pour the concrete foundation, and embed the foundation bolts.
● Steel frame installation: The steel frame components after trial installation are transported to the site and quickly assembled according to the numbers and marks to ensure that the nodes are firmly connected and the installation accuracy meets the design requirements.
● Protective construction: After the steel frame is installed, fire retardant paint and anti-corrosion coating are applied to ensure the protective effect.
Project Outcomes
1. Structural stability: The steel frame structure has excellent earthquake and wind resistance, ensuring the stability and safety of the substation under severe weather conditions.
2. Construction efficiency: Through factory trial installation, the on-site construction time and difficulty are reduced, greatly improving construction efficiency.
3. Protection effect: High-standard fire prevention and anti-corrosion design and construction ensure the long-term safe operation of the substation.
4. Economic benefits: Compared with traditional concrete structures, steel frame structures have higher cost-effectiveness, reduce maintenance costs and improve economic benefits.
