Bow Type power fittings are key connection and fixing components in power lines and optical fiber systems, and are widely used in high-voltage power transmission, communication optical cable installation, and railway electrification projects. Its bow-shaped structural design can effectively disperse stress and ensure the stability and safety of the line in complex environments. Handan Jinmai Fastener Manufacturing Co., Ltd. specializes in the production of Bow Type fittings, and its products include tension clamps, suspension clamps, pull rods, and matching iron accessories, which are suitable for steel-core aluminum stranded wire, OPGW optical cable and other scenarios.
1. High strength and durability: Forged with Q235/Q345 high-quality carbon steel, with a tensile strength of ≥500MPa, it meets the high load requirements of high-voltage lines.
2. Corrosion resistance: The surface is hot-dip galvanized, with a zinc layer thickness of ≥85μm, suitable for harsh environments such as humidity and salt spray.
3. Customized service: Supports customization of non-standard sizes and special materials (such as stainless steel and aluminum alloy) to meet the diverse needs of customers.
4. Precise adaptability: The product complies with the GB/T 2317.1-4-2008 industry standard and has passed the ISO9001 quality management system certification.
1. Forging: Use friction press and CNC punch for precision forging to ensure uniform mechanical properties of the bow structure.
2. Heat treatment strengthening: Improve material toughness through quenching + tempering process, and control hardness within the range of HB180-220.
3. Surface treatment: Use automated sandblasting and hot-dip galvanizing process to eliminate oxide scale and microcracks and improve anti-corrosion life.
4. Inspection process: 100% dimensional inspection, salt spray test and mechanical property sampling to ensure zero defects before leaving the factory.
