The Y-clevis is a key component used in power transmission lines to connect insulator strings to crossarms, fittings, or towers. Its unique Y-shaped structure effectively disperses mechanical stress, ensuring the stability and safety of high-voltage lines. Handan Jinmai Fastener Manufacturing Co., Ltd. specializes in the research and development and production of power fittings. Leveraging the strengths of the Yongnian fastener industry in Hebei Province, it offers a full range of custom hot-dip galvanized Y-clevis. These products are widely used in transmission towers, substations, and fiber optic cable installations.
1. High-strength, forged from Q235 carbon steel (optional 45# steel), precision-molded, with standard breaking loads ranging from 70kN to 210kN, meeting the specifications of the National Standard (GB), American Standard (ANSI), and the International Electrotechnical Commission (IEC).
2. Long-lasting corrosion protection is achieved through a hot-dip galvanizing treatment (zinc layer thickness ≥ 86μm) that passes the ISO 1461 salt spray test. It withstands harsh environments such as high temperature, high humidity, and industrial pollution, with a service life of over 30 years.
3. Flexible adaptability supports non-standard customization: Adjustable parameters include aperture diameter (16mm-50mm), arm length, and opening size, making it compatible with a variety of applications, including OPGW/ADSS cable fittings and porcelain insulator steel legs.
Handan Jinmai strictly adheres to a four-step quality control process:
1. Forging: Precision forging on a 10,000-ton friction press eliminates internal porosity defects;
2. Machining: CNC lathes refine holes and threads to an accuracy of ≤0.1mm;
3. Hot-dip galvanizing: Galvanizing at 450°C with a secondary passivation treatment to enhance adhesion;
4. Inspection: Tensile load testing (up to 120% of the design load) is performed on each piece, and a third-party quality inspection report is issued.
