Dead End Clamps (terminal tension clamps) are core fixtures for power and optical cable lines, designed specifically for anchoring ADSS/OPGW optical cables, steel strands, and conductors in high-altitude tension environments. Handan Jinmai Fastener Manufacturing Co., Ltd., with a large-scale factory with a registered capital of 2 million yuan (located in Yongnian District, Handan City, Hebei Province), utilizes a customized production model to meet the tension fixation requirements of diverse operating conditions. This product is widely used in high-voltage transmission towers, communication base stations, railway overhead lines, and other applications, ensuring cable stability in extreme conditions such as strong winds, ice, and snow.
1. High Strength and Corrosion Resistance
The main body is made of high-quality alloy steel, hot-dip galvanized (zinc layer thickness ≥ 80μm), and salt spray tested for over 1000 hours, making it suitable for use in highly corrosive environments such as coastal areas and industrial areas.
2. Adaptive Wire Diameter Design
The unique pre-twisted wire structure (such as the PAL35-1000 series) is compatible with wire diameters from 16 to 150 mm², protecting the cable surface through multi-point stress distribution.
3. Quick Installation and Maintenance-Free
The boltless crimping design increases installation efficiency by 50%, eliminating the need for regular tightening and maintenance.
4. Customization
We support non-standard customization, including special angles (0°-90°), vibration-resistant models, and insulated models.
The Handan Jinmai factory is equipped with a fully digitalized production line:
1. Precision Forging
Forming using a 630T friction press, the internal grain size reaches over 8, increasing strength by 30%.
2. Heat Treatment
A quenching and tempering process (quenching and tempering) achieves a hardness of HRC 22-26, balancing toughness and rigidity.
3. Surface Corrosion Protection
Triple Protection: Sandblasting, hot-dip galvanizing, and passivation sealing ensure a 30-year service life.
4. Intelligent Quality Inspection
100% dimensional verification is achieved through 3D scanning and 60kN tensile testing, complying with the national standard GB/T 2314.
