Main use of metal fittings

According to a certain classification, gold fittings can be divided into different types and types. Different types and models produce different performances and functions in actual use, and generate important functional values ​​in specific power use. The following describes different models and models. The main purpose of the type of fittings:

1 Suspended fittings: Suspended fittings are also known as supporting fittings or hanging clamps. This type of fitting is mainly used to suspend wires on insulator strings (used in linear towers) and suspension jumpers on insulator strings.

2 protective fittings: This kind of fittings are used to protect wires, insulators, etc., such as the equalizing ring for protecting insulators, the weights used to prevent the insulator strings, and the anti-vibration hammers and guard wires for preventing the wires from vibrating.

3 Anchoring fittings: Anchoring fittings are also called fastening fittings or tensile clamps. The metal fitting is mainly used for fastening the terminal of the wire to be fixed on the tensile insulator string, and is also used for fixing the lightning protection terminal and anchoring the cable. The anchoring hardware bears all the tension of the wire and the lightning protection wire, and some anchoring hardware also acts as an electrical conductor.

4 fixed fittings: fixed fittings are also called power plant fittings or high-current busbar fittings. The metal fittings are used for fixing and connecting various hard bus bars or soft bus bars and post insulators in the power distribution device, and most of the fixed metal fittings are not used as conductors, and are only used for fixing, supporting and hanging. However, since these fittings are used for large currents, all components have no hysteresis loss.

5 connection fittings: This kind of fittings is used to connect various bare wires and lightning protection lines. The connecting fittings bear the same electrical load as the wires, and most of the connecting fittings bear the full tension of the wires or lightning conductors.

6 Contact fittings: This kind of fittings are used for the connection of the hard busbars, the soft busbars and the outlet terminals of the electrical equipment, the T connection of the conductors and the parallel connection of the unsupported forces. These connections are electrical contacts and therefore require contact with the fittings to have high electrical conductivity and contact stability.

7 Coupling fittings: Coupling fittings are also called hanging wire parts. This fitting is used to connect the insulators in a string and the connection of the fittings to the fittings. It is subjected to mechanical loads.

The above is the specific use of different types of fittings, showing different values ​​and contributions in the power industry.
