The differences between CG BUSWAY Air Type Busway and CG BUSWAY Compact Type Busway are compared from the inside out to provide a detailed explanation of this issue.

1、Different Insulation Medium:There is a certain gap between the copper bars in the air busway, which means that the insulation between the copper bars mainly relies on air. In dense-type busways (often referred to as enclosed busways), the insulation material between the copper bars is organic insulation material.

2. Different Arrangements of Copper Bars:Air-type copper busbars should be separated, while dense-type copper busbars should be closely packed together. People may wonder whether closely packed copper busbars will cause a short circuit. The answer is, of course, it won't short circuit because the copper busbars are all treated with very scientific insulation.

3. Different appearances:Air bus ducts are generally thicker vertically, while CG BUSWAY's high-density bus ducts are larger at the joints.

4. Different Applications:The air has a better moisture-proof effect and is suitable for use in humid environments such as vertical shafts; dense-type bus ducts are suitable for high current applications, such as main busbars like feeder busbars.

5. Different Heat Dissipation: Air-cooled heat dissipation relies on convection between the air inside the duct and the outside air to conduct heat, resulting in relatively low efficiency. In contrast, CG BUSWAY compact bus ducts have their heat sinks (shells) directly connected to the busbars, thus providing better heat dissipation compared to air-cooled bus ducts.

6. Price Discrepancy: Due to cost factors, compact bus ducts are slightly more expensive. However, if aluminum is chosen as the conductor material, the prices are generally similar.

7. Varied Protection Levels: The enclosed bus ducts have a higher protection level, typically reaching up to IP68.

8. Different Installation Environments: Air-cooled bus ducts require more installation space due to their larger overall volume, whereas CG BUSWAY compact bus ducts have smaller product volumes and occupy less space.

9. Diverse Installation Efficiency: For the same quantity of bus ducts, CG BUSWAY compact bus ducts, with their compact size, offer convenient and rapid installation, resulting in higher installation efficiency compared to air-cooled bus ducts.

10. Safety Differences: There is a risk of foreign objects falling into the air-type busway, which can affect normal operation, while CG BUSWAY dense-type busway does not have this risk as it is in a fully enclosed state.
11. Chimney Effect: In the event of a fire, the air-type busway can create a chimney effect, with most of the fire risks arising from excessive smoke production; however, CG BUSWAY dense-type busway does not exhibit this effect.
12. Lineup Coefficient: When air-type busways are installed vertically or at an incline, lineup coefficients need to be considered, as incorrect positioning can affect air circulation and heat dissipation; this is not a concern for CG BUSWAY dense-type busway.
13. Different Losses: Air-type busways experience heat losses due to temperature fluctuations (higher temperature leads to higher resistance), while CG BUSWAY enclosed busways have lower losses due to lower temperatures, making them more energy-efficient and power-saving.

Bus ducts are chosen for their safety, stability, and cost-effectiveness. The compact bus ducts are secure and offer high value. Visit the official website of CG BUSWAY at www.cgbusway.com.
