A Brief Analysis Of The Classification Of Power Fittings.
overhead line connectors Classification: According to function and structure, it can be divided into suspension clamps, tension clamps, UT clamps, connecting hardware, splicing hardware, maintenance hardware, equipment clamps, T-type clamps, busbar hardware, guy wire hardware, etc.; according to use, it can be divided into line hardware and substation hardware. According to product unit overhead line hardware, it is divided into malleable cast iron, forged, aluminum-copper-aluminum and cast iron, a total of four units. According to the main function and use of the fittings, they can be roughly divided into the following categories: suspension fittings, also known as support fittings or suspension clamps. These fittings are mainly used to suspend conductors on insulator strings (mostly used on straight poles and towers) and to suspend jumpers on insulator strings; anchoring fittings, also known as fastening fittings or tension clamps.
These fittings are mainly used to fasten the ends of conductors, fixing them on tension insulator strings, and are also used for fixing the ends of lightning protection wires and anchoring guy wires. Anchoring fittings bear all the tension of the conductors and lightning protection wires, and some anchoring fittings also act as conductors; connecting fittings, also known as hanging parts. These fittings are used for connecting insulators into strings and connecting fittings to fittings. They bear mechanical loads.
Splicing fittings. These fittings are specifically used for splicing various bare conductors and lightning protection wires. The splice bears the same electrical load as the conductor, and most splicing fittings bear all the tension of the conductor or lightning protection wire; protective fittings. These fittings are used to protect conductors, insulators, etc., such as equalizing rings for protecting insulators, heavy weights to prevent insulators from being pulled off the string, and anti-vibration dampers and protective strips to prevent conductor vibration.
