What are power fittings?

                                                                        What are power fittings? 

Simply put, power fittings serve as the “skeleton and joints” of the power network, connecting conductors, insulators, towers, and other equipment to ensure the safe and reliable transmission of electricity. Most fittings endure significant tensile forces during operation, while some must also maintain good electrical contact. Even a single damaged fitting can cause line failures, making their quality and proper installation critical for safe power delivery.

What products are included in power fittings?

Power fittings come in numerous types with diverse applications. They can be primarily categorized by function and structure as follows:

1. Suspension Clamps: Also known as support fittings, these primarily suspend conductors (or ground wires) onto suspension insulator strings. Commonly found on straight towers.

2. Tension Clamp: Also known as Dead-end Clamps, these secure the conductor ends to the tension insulator string, bearing the full tension of the conductor or ground wire.

3. Connecting Fitting: Used to link insulators into strings and connect fittings to each other, primarily bearing mechanical loads.

4. Splicing Fitting: Specifically designed for splicing various bare conductors and lightning conductors. It must bear the same electrical load as the conductor and typically supports most of the conductor or lightning conductor's full tension.

5. Protective Fitting: Used to protect conductors, insulators, and other equipment, such as vibration dampers (preventing conductor vibration), spacers (maintaining separation between split conductors), voltage equalizing rings, and counterweights.

6. Terminal Connector: Primarily connects busbar leads in substations. Materials include copper transition terminal connectors and aluminum terminal connectors.

7. Bus-bar Fitting: Secures, suspends, and supports rigid or flexible busbars in distribution equipment.

8. Guy Fittings: Used to connect, secure, and adjust guy wires on towers, such as Stay Rods, Pole Top Make-Off, Guy Grips, Stay Plates, and Stay Insulators.

Additionally, based on application scenarios, electrical fittings are categorized into line fittings (for overhead transmission lines) and substation fittings (for use within substations).

The Importance of Selecting High-Quality Power Fittings

The safe and stable operation of power systems directly depends on the reliability of every component. Therefore, when selecting power fittings, ensure they comply with relevant international or national standards (such as GB, IEC, ASTM, etc.), possess excellent mechanical strength, conductivity, and corrosion resistance to withstand diverse climatic and environmental conditions in regions like Africa and South America.
