What is Busbar Trunking?
Busbar trunking is a system of electrical distribution. It uses busbars to conduct electricity. Busbars are metallic strips. They carry large amounts of current. This system is used in buildings, factories, and other places.
Types of Busbar Trunking
There are several types of busbar trunking. Each type has its own use. Let’s look at them one by one.
1. Sandwich Type Busbar Trunking
Sandwich type busbar trunking is very common. In this type, the busbars are placed close together. They are sandwiched between insulating materials. This helps in reducing the size of the system. It also improves the efficiency of power distribution.
Advantages:
- Compact size
- High efficiency
- Less heat generation
Applications:
- High-rise buildings
- Commercial complexes
- Industrial plants
2. Air Insulated Busbar Trunking
Air insulated busbar trunking is another type. In this type, air is used as the insulating medium. The busbars are placed with some space between them. This type is easy to install and maintain.
Advantages:
- Easy installation
- Simple maintenance
- Lower cost
Applications:
- Warehouses
- Manufacturing units
- Power stations
3. Cast Resin Busbar Trunking
Cast resin busbar trunking is a special type. In this type, the busbars are coated with resin. This gives them extra protection. They are safe from moisture and dust. This type is very durable.
Advantages:
- High durability
- Protection from moisture
- Dust resistance
Applications:
- Chemical industries
- Food processing plants
- Outdoor installations
4. Segregated Busbar Trunking
Segregated busbar trunking is another type. In this type, the busbars are placed in separate compartments. Each compartment has its own insulation. This helps in preventing faults.
Advantages:
- Fault prevention
- Easy to identify issues
- Better protection
Applications:
- Data centers
- Hospitals
- Critical installations
5. Open Type Busbar Trunking
Open type busbar trunking is a simple type. In this type, the busbars are exposed. They are mounted on insulators. This type is easy to inspect. But it needs more space.
Advantages:
- Easy inspection
- Simple design
- Low cost
Applications:
- Electrical rooms
- Substations
- Power distribution centers
Choosing the Right Type
Choosing the right type of busbar trunking is important. It depends on the application. It also depends on the environment. Let’s look at some factors to consider.
1. Load Requirements
Consider the load requirements. Different types have different capacities. Choose the one that meets your needs.
2. Space Availability
Check the space available. Some types need more space. Others are compact.
3. Environmental Conditions
Look at the environmental conditions. Some types are better for harsh environments. Others are not.
4. Maintenance Needs
Think about maintenance needs. Some types are easy to maintain. Others need more effort.
