address : YantaiQixiaTaocunindustrial park



We are factory supply of power line fitting.Iron or aluminum metal accessories widely used for transmission lines, collectively referred to as fittings. There are many kinds of metal fittings, such as various clamps for installing wires, various hanging loops constituting insulator strings, various crimping pipes for connecting wires, repair pipes, and various types of split wires. In addition, there are various types of cable fittings for pole towers, and the size of the protective conductors must be matched. Most of the metal fittings need to withstand large pulling forces during operation, and some also need to ensure good electrical contact. It is related to the safety of the wires or towers. Even if one is damaged, it may cause line faults. Therefore, the quality, proper use and installation of the fittings have a certain impact on the safe transmission of the line.
