The pigtail hook is a core fixture for overhead optical/cable wiring, specifically designed for managing excess cable at the terminals of power and telecommunication cables, such as OPGW and ADSS. Manufactured by Handan Jinmai Fastener Manufacturing Co., Ltd. using pre-twisted wire, it is suitable for coiling and securing pigtail cables in locations such as power towers and communication base stations, effectively preventing cable displacement and damage caused by wind vibration, ice, and snow loads. The product can be customized to accommodate various cable diameters and installation environments.
1. High Compatibility
- Supports customizable optical cable specifications from 5mm to 30mm, compatible with a variety of cable types, including OPGW, ADSS, and drop-cord cables.
2. Fatigue-Resistant Design
- Pre-twisted construction disperses stress, passing IEC and NFC international standards testing and boasting a corrosion resistance lifespan exceeding 30 years.
3. Lightweight Installation
- Made of one-piece stainless steel (available in 304/316L), it is 40% lighter than traditional hardware and supports quick-lock installation at high altitudes.
4. Safety Protection
- Surface passivation prevents cable wear, and a built-in rubber cushion provides dual cushioning protection.
1. Precision Cold Forging
- The base is processed using a CNC punch press and friction press, with an accuracy control of ±0.1mm.
2. Automated Pre-Twisting
- A fully automated production line twists high-strength aluminum alloy strands with a tensile strength of ≥1,200 MPa.
3. Double Surface Treatment
- The base is hot-dip galvanized (thickness ≥86μm) and then electrostatically sprayed, passing a 1,000-hour salt spray test.
