Copper bus bar suppliers

When it comes to electrical conductors, copper has been a popular choice for a long time. Its superior electrical conductivity makes it an ideal material for various electrical applications. However, not all copper is created equal. Among the different types of copper, ETP or Electrolytic Tough Pitch stands out as having the highest electrical conductivity. In this blog post, we’ll discuss the benefits of ETP copper bus bars and why they are the conductor of choice in many industries.

What Are ETP Copper Bus Bars?

Copper bus bars are copper strips used in electrical power distribution and provide a convenient method of connecting many individual circuits, protection systems, control equipment, and instruments. They can be flat or tubular and usually consist of high-conductivity copper alloys such as CDA 110 or ETP copper. Copper bar stock is highly conductive compared to other materials such as aluminium, steel and iron due to its low resistivity rate, making it a preferred material in electrical power applications. Copper bus bars also offer low inductance characteristics, further enhancing their ability to transport large currents with minimal losses.

Exceptional Electrical Conductivity

The electrical conductivity of ETP copper is higher than any other type of copper. This means that ETP copper busbars can carry more electrical current than other copper bus bars. This increased conductivity of ETP copper is due to its low impurity levels, making it a more effective electrical conductor. The higher the current, the more significant the benefits of using ETP copper busbars.

Resistance To Corrosion

Copper is known to corrode over time, compromising the electrical transmission process. However, ETP copper has a uniform crystal structure, making it highly corrosion-resistant. This makes ETP copper bus bars an ideal choice for applications where the conductor is exposed to harsh environmental conditions. The corrosion resistance ensures the longevity of the ETP copper busbars and makes them ideal for use in marine and industrial applications.

Excellent Thermal Conductivity

ETP copper also has excellent thermal conductivity, which makes it a good choice for heat-dissipating applications. Its ability to conduct heat effectively means it can help prevent overheating and potential malfunctions. This makes ETP copper bus bars ideal for use in applications that require high voltage, such as transformer applications.


ETP copper busbars may appear more expensive than other copper conductors, but they offer a long-term, cost-effective solution. The high electrical conductivity of ETP copper means that less copper is needed for the same electrical current, reducing the amount of material required and overall costs. Moreover, the resistance of ETP copper to corrosion ensures that the bus bars require less maintenance, resulting in greater cost savings over time.

Variety Of Applications

The superior electrical conductivity and other unique properties of ETP copper busbars make them the conductor of choice in numerous applications. These include power distribution, circuit breakers, switchgear, and installation in generators, transformers, and motors.


ETP copper bus bars offer an alternative to conventional copper conductors. The exceptional electrical conductivity, resistance to corrosion, excellent thermal conductivity, cost-effective nature, and variety of applications make ETP copper bus bars ideal for a diverse range of electrical applications. Conducting excellence with ETP copper busbars ensures a reliable electrical transmission process, reduced maintenance costs, and increased operational efficiency.
