In contrast to the "grid-like" structure of the air type busbar, the compact busbar's "sandwich" structure offers the evident benefits of a smaller volume and reduced space occupation.

  The resistance, capacitance reactance, and inductance reactance of the transmission lines are the primary factors determining the voltage drop index of the general low-voltage system. The eddy current phenomenon is evident in the air-type enclosure, which is constructed from magnetic material (steel). This is evidenced by the substantial capacitance reactance and inductance reactance, as well as the pronounced voltage decrease and substantial power loss observed. Nevertheless, the impedance of the busbar system is significantly reduced by the compact structure of the compact busbar. The aluminum-magnesium alloy enclosure also prevents the occurrence of magnetic hysteresis and eddy current phenomenon, which leads to a very low energy consumption and a very small voltage drop for the complete system. It generates less heat and dissipates heat rapidly.

  The voltage drop index of transmission lines in a general low-voltage system is primarily determined by the resistance, capacitance reactance, and inductance reactance of the lines. The air-type enclosure is constructed from magnetic material (steel), and the eddy current phenomenon is readily apparent. This is evidenced by the substantial capacitance reactance and inductance reactance, as well as the pronounced voltage decrease and substantial power loss. On the other hand, the impedance of the busbar system is significantly reduced by the compact structure of the compact busbar. In addition, the aluminum-magnesium alloy enclosure prevents the occurrence of magnetic hysteresis and eddy current phenomenon, which leads to a minimal voltage loss and extremely low energy consumption for the entire system. It produces a reduced amount of heat and dissipates it rapidly.

   The enclosure of the air type busbar is primarily assembled through bolt connection, whereas the compact busbar is assembled using a completely automatic riveting system. In the former scenario, bolt loosening and shedding are highly probable during the electrical operation, which is accompanied by vibration, thereby presenting a potential safety hazard. Conversely, the latter eliminates the conventional fastener connection, maintains high assembly accuracy, and eliminates human factors while maintaining excellent electrical continuity.

 The "chimney effect" is an unavoidable characteristic of the air-type busbar. When a fire occurs at a single location, the porous structure of the structure functions identically to a chimney, thereby accelerating the fire's spread and posing a significant safety hazard.

  The air type busbar is more adaptable to environments with comparatively high humidity and can accommodate high-rise buildings. It has less stringent environmental requirements. It has a clear advantage in terms of product durability.

   The air type busbar is particularly convenient for maintenance. In the event of an emergency, the insulation components and conductors can be disassembled and replaced on site, and the air type utilizes the insulation spacer plus bolt fixation method.

   The insulation effect of the air type busbar channel is greatly enhanced over that of the compact busbar channel due to the use of insulation spacers and fastener fixation.
