Product Introduction
U-0770 U Shape Shackle
The U-0770 is a light-load U Shape Shackle with a nominal breaking load of 70kN. It is mainly used in 10kV rural branch lines, street lighting lines, and short-span light-load lines to connect insulator strings to poles and towers. Made of high-quality carbon steel with hot-dip galvanizing, this fitting features a compact structure, easy installation, and corrosion resistance suitable for humid and hot environments. Widely used in small distribution networks and short-distance power lines in Africa and Southeast Asia, it is the most commonly used standard connection hardware for lightweight poles, offering high cost-effectiveness and strong versatility.
