Overhead line fittings are accessories that connect and combine various devices in the power system to transfer mechanical and electrical loads or to play a protective role.
Overhead line fittings have the function of mechanical for electrical connections and interfaces that hold insulators and conductors in place. In the relevant standards, fittings are updated periodically as fittings uniformly and may consist of elements or accessories.
Fittings for different conductors are designed for termination, suspension or connection of conductors and are connected directly to the conductor. This category includes dead-end clamps, suspensions, branch clamps, connectors, bundle spacers and vibration-proof fittings. Depending on the function, they may form an assembly containing multiple elements, including, for example, clamps for connecting rods.
Accessories for insulators and other accessories are designed to connect the tensioner assembly to the connection point at the support.
Overhead line fitting is an important component applied to the "grid", where there are a very large number of crossover nodes in the transmission and distribution power system. The line crossings form a network and each line crossing needs to be fixed. There are many substations that form the intermediate nodes of the grid and many power towers that support the backbone of the grid. The transmission of electrical energy requires conductor contact and sufficient current-carrying areas to maintain high power levels. That is, good and solid contact between the grid equipment and conductors such as conductors is guaranteed.
Concept of overhead line jigs
Power lines are widely used for metal fittings such as iron, aluminum or aluminum alloy.
Boost substation and buck substation distribution equipment and conductors, conductors and conductors, transmission line conductors themselves connected, insulators connected into strings. Conductors, insulators, and other metal (iron, aluminum, or aluminum alloy) accessories used for their own protection become overhead line fixtures.
Which is used for overhead transmission lines overhead line gold is called line gold. Line fixture for overhead transmission lines between the wire connection, insulator connection, insulator and tower, insulator and wire connection. It must have sufficient mechanical strength and assembly as well as operational flexibility. Simply put, metal parts are the nodes and stress points of the "net" of the power grid, serving the functions of connection, fastening, transferring mechanical loads, and protection. However, the net requires a high level of safety for the fixed connection of these nodes and stress points and requires specific specifications and production processes.
