Various Classifications And Application Scopes Of Electrical Fittings

overhead line hardware classification is also diverse, which can be uniformly divided into the following categories:

① Connecting hardware, mainly used in overhead power lines in overhead power line connectors construction, and used in substations built by power bureaus. overhead power line hardware is generally used to use connecting hardware to string suspension insulators and hang them on poles and towers. Another function is to use connecting hardware to connect the suspension wire clamps for straight-line tower insertion or the tension wire clamps for non-straight-line tower insertion to the insulator string. There are many places where connecting hardware can be used.

② Suspension wire clamps, this type of transmission line hardware is mainly suitable for hanging wire insulator strings on poles and towers, and hanging jumpers on insulator strings.

③ Protective hardware, as the name suggests, is mainly reflected in the protection of other electrical transmission line hardware fittings functions, reducing the vibration amplitude of overhead power line conductors and lightning arresters, and uniform shielding on lines above 330kv and substation insulator strings. This type of products includes: shock-absorbing hammers, spacer rods, etc.

④ Cable fittings, such as the DTL, DT, and DL series of copper-aluminum terminal blocks are used for the transition connection of various round, semi-circular, and fan-shaped aluminum wires, power cables, and copper ends of electrical equipment in distribution devices. This type of product also plays a vital role in hardware fittings for transmission lines.\
