Working Principle and Practical Applications of 35 kV Substations

2026-02-16 10:13:41

A 35 kV substation mainly converts high-voltage electrical energy into medium- and low-voltage power suitable for end users through transformers and switching equipment. Its core working principle involves stepping the voltage up or down via transformers to meet the requirements of different transmission and distribution networks. In practical applications, 35 kV substations are commonly used in urban and industrial power supply systems, especially as an important part of the distribution network.

During operation, the substation must strictly follow established operating procedures to ensure equipment safety and energy efficiency. Operators are required to closely monitor the operating status of the equipment, and any abnormalities should be promptly identified and addressed through troubleshooting. In addition, with increasingly stringent environmental regulations, greater emphasis is being placed on environmental protection and improvement measures in practical applications to reduce the impact on the surrounding environment. In humid or dusty conditions, dustproof and moisture-proof measures are also critical, as they not only extend the service life of the equipment but also enhance operational safety.
