Electric power fittings application
I.The successful application of corrosion-resistant transmission hardware in coastal overhead line projects
High-strength aluminum alloy (ASTM B221 standard) is combined with hot-dip galvanized steel (GB/T 13912 standard) to ensure resistance to salt spray corrosion. Key components use silicone rubber sealing rings, which can withstand extreme temperature differences (-40℃ to 120℃).
Production process
1）Precision Casting: Through 3D modeling to optimize mold design, material loss rate is reduced by 15%;
2）CNC Machining: Error precision ≤ 0.05mm, suitable for different specifications of wires;
3）Surface Treatment: Triple anti-rust process (phosphating + electrostatic spraying + epoxy resin coating), service life extended to over 25 years.
II. Product Advantages and Application Performance
---Core advantages
1)Strong corrosion resistance: No rust after continuous use for 3 years in coastal high-humidity and high-salt environments;
2)Lightweight design: 30% lighter than traditional cast iron fittings, reducing the load on the tower frame;
3)Easy installation: Modular structure compatible with mainstream conductor models, increasing construction efficiency by 40%.
---Application fields
1）High-voltage/Ultra-high-voltage transmission and distribution lines, railway electrification projects, new energy photovoltaic/wind power grid connection projects;
2）Case scenario: In a coastal province, the 220kV overhead line renovation project successfully replaced over 3,000 sets of old hardware.
III. Customer Feedback
A power engineering company commented:
"The products performed stably during the typhoon season, with no loosening or oxidation issues, and maintenance costs were reduced by 60%."
Project data: The annual average failure rate of the line dropped from 1.2 times per kilometer to 0.3 times per kilometer after installation.
