1. What are the hardware for overhead transmission lines?

Hardware can be said to be a little helper in overhead transmission lines. They help support and fix conductors and ground wires, connect insulators into strings, and protect conductors and insulators. They are mainly made of iron, aluminum or aluminum alloy, with super strong mechanical strength and flexible assembly characteristics.

2. Basic classification of hardware

Suspension wire clamps
Suspension wire clamps are used to hang conductors and ground wires on insulators. Common ones are U-bolt styles, usually made of iron or aluminum materials, and the selection of different lines is also different.

Strain wire clamps
This hardware is mainly used to bear the tension of the conductor and hang it on the tension insulator or pole tower. Depending on the structure, it can be in the form of compression type, bolt type, etc.

Connecting hardware
This part of the hardware is responsible for connecting insulators, suspension wire clamps and tension wire clamps. Common types include ball-socket series and ring-chain series.

Connection hardware
When the length of the wire is insufficient, this hardware comes in handy and is mainly responsible for connecting them. The methods of use include clamping and crimping.

Protective fittings
Protective fittings are important. They help protect conductors and electrical devices. They are divided into electrical and mechanical protective fittings, such as equalizing rings for insulators.

Wire fittings
This type of fittings is mainly used at the corners and terminal towers of power lines to help fix, adjust and connect.

3. Material of fittings
Although the materials of fittings are divided into iron, aluminum and aluminum alloy, each material has its unique application and advantages, suitable for different environments and needs.

4. Summary

Fittings play a vital role in overhead transmission lines. With the development of science and technology and the application of new materials, their functions will become more and more powerful in the future! I hope today's sharing can give you a deeper understanding of these friends!
