First of all, we should make it clear that power fittings are important components used in overhead transmission lines. Power fittings used in overhead transmission lines are called line power fittings. There are many cross points in our power system in the transmission lines, and the connection places use power fittings. Power fittings are mainly used to connect and combine various devices in the power system to transfer mechanical loads Electrical load and metal accessories with certain protection function.

If the transmission line is complex, then the electric power fittings are not simple, and the types and purposes are different. For example, various crimping pipes and repair sleeves for connecting conductors, various types of spacers on bundled conductors, various wire clamps for installing conductors, various hanging rings for forming insulator strings, in addition, various stay wire fittings for poles and towers, as well as the size of protective conductors, must be coordinated;

If the relationship between electric power fittings and power transmission lines is likened to an object, it is coffee and coffee partners, because they are compatible; The parts used by different transmission lines are different, but the only thing that remains unchanged is that the transmission line accessories must be power fittings, because the transmission lines have high stability requirements for the fixed connections at these nodes and stress points, and require specific specifications and manufacturing processes, so the power fittings are also a special part.
