Industrial: It is widely used in industrial fields, such as steel, petrochemical and other industries that require a large amount of power supply.

Commercial: S20-2500kVA oil-immersed transformers are also used in shopping malls, office buildings and other commercial facilities to meet power demand.

4. Precautions for the use of S20-2500kVA oil-immersed transformer

Safe operation: In the process of operation, it is necessary to follow the safety operation procedures to prevent safety accidents. At the same time, the operation status of each component of the transformer should be checked regularly to ensure its safe and stable operation.

Maintenance: Perform regular maintenance, including cleaning the appearance, checking fasteners, checking the oil level, etc. At the same time, the transformer oil should be changed regularly to maintain the cleanliness and quality of the oil.

Operating environment: The transformer should be installed in a dry, well-ventilated, non-corrosive gas environment. In addition, maintain proper indoor temperature and humidity to prevent the transformer from overheating or getting wet.

Prevent overload: The transformer should be avoided from running overload for a long time, so as not to cause damage to the equipment or shorten the service life.

Prevention of lightning hazards: During the thunderstorm season, lightning protection measures should be taken to avoid damage to the transformer caused by lightning.

5. Maintenance of S20-2500kVA oil-immersed transformer

Visual inspection: Regularly check whether the appearance of the transformer is in good condition, whether there is leakage, deformation, etc.

Oil level check: maintain a proper oil level, regularly check whether the oil level is normal, if the oil level is too low or too high, it should be dealt with in time.
