First of all, it should be clear that electric power fittings are important parts used in the “power network”. Before understanding the fittings, we should first understand the characteristics of the power network.
Because there are so many intersecting nodes in our power system, we often refer to it figuratively as the “grid”. So what does the grid, as a “net”, have in common with spider webs, wire nets and fishing nets
A network is formed only when lines are crossed, and if any network is to be stable, the intersections of lines must be fixed. In other words, the “nodes” need to be fixed, otherwise there will be no network. This characteristic also applies to the power network, which is a complex network composed of many transmission and distribution lines. Every substation and even every base tower can be regarded as a “node” of the power network.
In the dotted box is the power network. In this figure, we can understand that there are many substations constituting the intermediate nodes of the power grid in the whole large power grid, and there are many power poles and towers supporting the main lines of the power grid. The transmission of electric energy requires conductor contact, and sufficient current-carrying area should be guaranteed under large power, that is, good and firm contact should be guaranteed between the equipment of power grid and conductors and other conductors.
Let’s take a look at the concept of gold ware:
What is a widely used with the electric power line of iron, aluminum or aluminum alloy and other metal accessories, step-up substation and step-down transformer substation equipment and conductor, a conductor and wire in distribution equipment, transmission line conductor connection and connection string, conductor and insulator’s own protection used metal (iron, aluminum or aluminum alloy) attachment called fittings. Power fittings are metal accessories that connect and combine all kinds of devices in the power system and play the role of transferring mechanical load, electrical load and some protection. The power fittings used for overhead transmission lines are called line fittings. Line fittings are used for connection between conductors, connection between insulators, connection between insulators and towers, and connection between insulators and conductors on overhead transmission lines. It must have sufficient mechanical strength and flexibility to assemble and operate.
Tell commonly, gold appliance is power network this piece “net” the node and force point place connect, fasten, transfer mechanical load, protect the function such as the part that do with metal, just this net to these node and force point place fixed connection safety requirement is higher, need has specific specification and make craft
