A hot-dip galvanized, wedge-type strain clamp designed for quick installation and reliable tension holding on overhead power lines. Its adjustable design accommodates various conductor sizes, providing superior grip strength and vibration resistance without damaging the cable.
The Jiujin UT Wedge Type Adjustable Strain Clamp is an innovative solution for dead-ending and tensioning overhead conductors. Engineered with a unique wedge-locking mechanism, this clamp applies uniform pressure on the conductor, ensuring a secure hold that improves with increasing tension load. Manufactured from high-strength malleable iron or carbon steel with a heavy-duty hot-dip galvanized finish, it offers exceptional corrosion resistance and durability. The adjustable design eliminates the need for multiple size-specific clamps, reducing inventory costs and simplifying field installation. Produced at our Hebei factory, this clamp is designed to withstand extreme environmental conditions while maintaining reliable performance in electrical distribution networks.
