U-shaped shackles are one of the most fundamental and commonly used components in power connecting fittings. Named for their U-shaped main body, their core function is to realize mechanical connections between poles and towers, insulator strings, and other fittings, while transmitting the mechanical loads of the power line.
Here are main features:
Simple and reliable structure: The main body is made of U-shaped steel, with bolt holes at both ends. Connection is achieved through bolt fastening, which is easy to install and not easy to loosen.
Strong material adaptability: Hot-dip galvanized steel (for corrosion resistance) is used in conventional scenarios, stainless steel is selected for highly corrosive environments such as coastal areas and industrial zones, and steel with better low-temperature toughness is considered for high-altitude areas.
