Aluminum Alloy Strain Clamps are one of Handan Jinmai Fastener Manufacturing Co., Ltd.'s core products, designed specifically for power transmission and distribution lines and fiber optic cable installation. Made from high-strength aluminum alloy through precision machining, these clamps are primarily used to secure conductors, optical cables, or electrical cables, ensuring stability and security in complex environments. Since its establishment in 2010, the company has been deeply engaged in the power hardware industry, providing customized services to meet diverse project needs. These clamps are widely used in industries such as power, communications, and railways.
1. Lightweight Design: Aluminum alloy has a low density and weighs only one-third of traditional steel fittings, making it easy to transport and install.
2. High Corrosion Resistance: The anodized surface protects against harsh environments such as moisture and salt spray, extending its service life.
3. Excellent Conductivity: Suitable for high-current applications, it reduces power loss and meets energy-saving and environmental standards.
4. High Strength and Flexibility: With a tensile strength of ≥150 MPa, it is compatible with a variety of conductor sizes (16-400 mm²) and can be customized with segmented structures to meet different tension requirements.
5. Strong Compatibility: It supports the fixing of optical cables such as ADSS and OPGW, as well as steel-core aluminum stranded wire, and is compatible with various pole and tower types.
1. Raw Material Selection: 6061-T6 aluminum alloy is selected, and spectral analysis is performed to ensure that the composition meets the standards (Si ≤ 0.6%, Mg 0.8-1.2%).
2. Pre-twisted Forming Technology: Utilizing a domestically advanced pre-twisted wire production line, this ensures uniform stress distribution between the clamp and the conductor, avoiding stress concentration.
3. Heat Treatment: Solution treatment and artificial aging in an aging furnace enhance material hardness and fatigue resistance.
4. Precision Machining: CNC lathes and stamping equipment operate in tandem to ensure dimensional accuracy of ±0.1mm and surface roughness ≤Ra3.2.
5. Quality Inspection: Each batch of products undergoes salt spray testing (≥72 hours), tensile testing (breaking load ≥1.5 times the rated load), and conductivity testing.
