For instance, the GPU400L-330090 model, with its 26-meter cable length, is designed to accommodate various aircraft sizes and parking scenarios. This cable coil GPU ensures that power can be delivered efficiently to aircraft, regardless of their position on the tarmac. Airport layouts and gate designs also play a crucial role in determining the optimal cable length, as GPUs need to be versatile enough to service different areas without compromising on power delivery or safety.
Operational Flexibility and Mobility Requirements
Operational flexibility and mobility requirements are key factors in selecting the appropriate cable length for cable coil GPUs. Airports with diverse aircraft types and frequently changing gate assignments benefit from GPUs with longer cables, as they provide greater flexibility in positioning the unit. The cable coil design, as seen in models like the GPU400L-330090, allows for easy extension and retraction, enhancing mobility and reducing tripping hazards on the tarmac. This feature is particularly valuable in busy airports where ground equipment needs to be quickly repositioned or stored. The 26-meter cable length of this cable coil GPU strikes a balance between reach and manageability, ensuring that ground crews can efficiently service aircraft without the need for frequent GPU relocation.
Power Loss and Voltage Drop Considerations
When selecting cable lengths for cable coil GPUs, power loss and voltage drop are critical considerations. Longer cables can lead to increased resistance and, consequently, power loss along the cable's length. This is particularly important for high-power units like the 90kVA GPU400L-330090. The cable coil GPU design helps mitigate some of these issues by allowing for optimal cable management and reducing unnecessary cable exposure. Manufacturers like ACSOON take these factors into account when designing their cable coil GPUs, ensuring that even with a 26-meter cable, the unit can maintain its output of 3×200VAC at 400Hz with minimal loss. The phase angle symmetry of 120°±1° for balanced loads and 120°±2° for 30% unbalanced loads demonstrates the precision engineered into these systems to compensate for potential power degradation over longer cable lengths.
How do different cable lengths affect the performance of cable coil GPUs?
Impact on Power Delivery and Efficiency
The length of cables in cable coil GPUs has a direct impact on power delivery and overall efficiency. Longer cables, while providing greater reach, can potentially result in increased voltage drop and power loss due to resistance. However, advanced cable coil GPU models like the GPU400L-330090 are designed to minimize these effects. With its 26-meter cable length, this unit strikes a balance between extended reach and maintaining power integrity. The cable coil design allows for efficient power transmission by reducing unnecessary exposure and potential damage to the cable. This results in consistent power delivery of 3×200VAC at 400Hz, even at the cable's full extension, ensuring that aircraft receive the necessary power without significant loss or fluctuation.
