110kv/132kv/135kv lattice structure transmission tower

DESHI’s approach to manufacturing 110KV, 132KV, 135KV overhead line (OHL) steel towers illustrates their commitment to technical precision, client customization, and quality control, making them stand out in the industry for these types of projects. Here’s a breakdown of their process:

1. Design and Engineering: DESHI leverages the expertise of a main design engineer from the USA, utilizing advanced design software like PLS to conduct structural calculations and create precise geometrical frame drawings. This ensures that each tower design is optimized not just for structural integrity but also for cost-effectiveness and compliance with client specifications.
2. 3D Modeling and Documentation: The use of 3D models is particularly noteworthy as it helps in visualizing the complete structure before manufacturing. This step is crucial for eliminating potential errors in the design and drawing stages, ensuring that the production phase proceeds without costly mistakes or delays.
3. Quality Assurance and Control: DESHI’s dedicated QA & QC teams enforce strict quality control measures throughout the manufacturing process. They adhere to a detailed QC plan tailored to meet or exceed client requirements, ensuring the highest standards of quality and reliability.
4. Galvanizing Process: The galvanizing process involves several critical steps:Caustic Cleaning: Removes impurities and prepares the steel surface.Pickling: Treats the steel with an acid solution to remove mill scale and iron oxides.Fluxing: Coats the steel in a flux to prevent oxidation before it enters the galvanizing bath.
5. Duplex Surface Treatment: Following galvanization, DESHI applies a duplex coating—a combination of galvanizing and painting—in their own paint shop. This secondary finish not only enhances the aesthetic appeal of the towers but also significantly improves their corrosion resistance, thereby extending their operational life.
6. Client-Centric Production: By producing shop drawings, component lists, and full production documentation, DESHI ensures that all client expectations are met or exceeded, from the initial design phase through to the final delivery of the product.

The processes described here highlight DESHI’s capacity to deliver high-quality, durable 110KV, 132KV, 135KV OHL towers tailored to specific client needs, making them a valuable partner for projects requiring reliable overhead transmission solutions.
