1.Multiple Circuits, High Reliability, Low Losses: When transmitting the same power with equivalent conductors, compared to a 10kV 200 kVA 3 phase utility transformer, a 22 kV 200 kVA 3 phase utility transformer extends the supply radius by 60%, expands the coverage by 1.5 times, and increases the power transmission capacity by a factor of 1, while reducing transmission losses by 75%.
2.Cost-Effective and Economical: Implementing a 20kV distribution network for power supply can result in reduced investments and land requirements for larger capacity customers. It offers an optimized power supply solution, while operating and maintenance costs remain largely comparable to those of 10kV systems.
3.Enhanced Power Delivery Capability, Wider Coverage: The power delivery capability of a 22 kV 200 kVA 3 phase utility transformer is approximately twice that of a 10kV 200 kVA 3 phase utility transformer, and the coverage area is about 2.5 times larger.
4.Long-Distance Transmission: There is significant untapped potential for supplying power to remote rural areas. Using a 20kV long-distance power supply approach can reduce losses, alleviate issues related to excessive voltage, and take advantage of long-distance transmission capabilities in low load density regions.
