Busbar plays a crucial role in electrical systems, ensuring safe and efficient transmission of electrical power. This article will help you gain a deeper understanding of Busbar, from its definition, structure, and classification to its applications and outstanding advantages.

1. What is Busbar?

A Busbar is a type of conductive metal bar used to distribute high currents in an electrical system. Busbars are usually made of copper or aluminum and can be plated with Silver or Nickel for increased corrosion resistance.

2. Structure of Busbar

Busbars are typically made of copper or aluminum and can be Silver or Nickel plated for increased corrosion resistance. The structure of the Busbar can vary depending on the purpose of use, usually the Busbar will be made up of the following components:

2.1. Conductive core

• The core of the busbar is the main component of the busbar. It is made of a good conductor material such as copper or aluminum.
• The core of the busbar can have different shapes, such as flat, round, square, or U-shaped.
• The size of the core depends on the expected current that will run through it.

2.2. Electrical case:

• The busbar has an outer sheath that covers the core to ensure safety and prevent electrical leakage.
• The materials commonly used are PVC, XLPE, EPR, or silicone.
• The insulation sheath can have different colors to easily distinguish the electrical phases.

2.3. Accessory:

• Busbars can be equipped with additional accessories such as support bars, clamps, connectors, etc. to support installation and use.
• These accessories are made from various materials such as steel, aluminum, plastic, etc.

3. Busbar classification

Busbars can be classified according to various criteria such as material, shape, insulation, protection level, application, etc.

In general, busbars are classified into 6 types as follows:

3.1. Flexible busbar

3.2. Solid Busbar

3.3. Aluminium Busbar

3.4. Braided busbar

3.5. Busbar CU-AL

4. Features of Busbar

4.1. Conducts and distributes electricity

Busbar is a good conductor of electricity, capable of carrying large currents with little power loss. Therefore, busbar is used to transmit electrical energy from the power source to electrical equipment efficiently. Busbar can be used to distribute electricity to different electrical devices in an electrical system. Busbar is commonly used in electrical cabinets, transformer stations and power plants.

4.2. Connect and protect electrical systems

Busbars can be used to connect different electrical devices in an electrical system. Busbars help to create a safe and reliable connection between electrical devices.

Busbars can be used to protect the electrical system from short circuits and overloads. Busbars can be equipped with protective devices such as fuses or circuit breakers to interrupt the electrical circuit in the event of a fault.

In addition, busbars are insulated, which helps to protect users from electric shock. Busbars have a high load capacity, which helps to reduce the risk of electrical accidents.

5. Advantage of Busbar

• Higher current carrying capacity: Busbars can carry much larger currents than electrical cables of the same size, meeting the power supply needs of high-power consuming devices.
• High temperature resistance: Due to the insulation layer, busbars can operate in high temperature environments.
• Corrosion resistance: Busbars will be coated with an anti-corrosion layer to be suitable for use in high humidity environments.
• Fire resistance: Busbars can be used in environments with a high risk of fire and explosion.
• High reliability: Busbars are more reliable than electrical cables. Busbars have a higher resistance to heat, shock and corrosion, are less dangerous and cause less damage. In addition, busbars have a longer life than cables.
• Easy installation: Busbars can be designed in many different forms to suit different applications. This makes it easier to install and maintain than electrical cables. Busbars can also be installed in a variety of environments.

6. Application of Busbar

Busbar is widely used in a variety of fields, including :

6.1. Electrical System

• Electrical Cabinets: Distributes power to the devices within the cabinet.
• Power Stations: Connects transformers, circuit breakers, isolators, transformers, and current transformers.
• Residential Electrical System: Distributes power to different areas of the house.
• Industrial Electrical System: Provides power to high-performance equipment.

6.2. Cars, motorbikes, trains

• Modular battery: Connects the cell batteries, conducting electricity in the battery of the electric vehicle
• Electrical system: Conducts electricity from the battery to the components of the electric vehicle

6.3. Recycled energy

• Solar system: Connect solar panels.
• Wind energy system: Conducts electricity from the wind turbine to the electrical system.

6.4. In addition, Busbar is also used in a number of other fields such as:

• In the mining industry, Busbar is used to supply power to mining equipment.
• Busbar provides power for high-performance equipment: welding machines, laser cutting machines,…
• Busbar provides light source systems, telecommunications equipment,…

7. Conclusion

With its diverse features and applications, Busbar plays an important role in ensuring safe, efficient and reliable power supply for electrical systems.

In addition, Busbar also has strong development potential in the future, with the development of industries such as renewable energy, electric vehicles and smart homes.
