132kv 110kv 50mva 125mva Oil immersed transformer

132kv 110kv 50mva 125mva Oil immersed transformer realizes voltage conversion and load management for city grid. The capacity selected varies in different areas, and the larger the capacity, the more powerful cooling is required with the addition of fans. The enclosure is equipped with noise reduction equipment to avoid excessive noise during operation, and Lugao Power Co., Ltd strictly follows international standards in design, and each production step is equipped with professional quality control instruments. The production line is equipped with professional quality inspection instruments. The details are strictly grasped on the production line, which builds a good image for Made in China.

Lugao 132kv 110kv 50mva 125mva Oil immersed transformer Introduction

In terms of materials, the 132kv 110kv 50mva 125mva Oil immersed transformer utilizes high permeability silicon steel sheets and is 100 percent all copper wound. In terms of cooling, 4-5 sets of fans are used for 50MVA capacity and 8 sets of fans are used for 125MVA capacity. The insulation medium is a combination of insulating paper and synthetic ester oil, as is the capacitive casing. The oil temperature and oil level are monitored in real time by sensors. The transformer is also equipped with protective devices such as pressure relief valves and oil filters. Careful design in every detail.

132kv 110kv 50mva 125mva Oil immersed transformer uses transformer oil for cooling and insulation, the oil submerges the entire core and windings, which enables more even heat dissipation, the oil naturally convects when heated and sends the heat generated by the windings and the core to the heat sinks without localized overheating alarms. Transformer oil can also quickly extinguish the arc under high temperature decomposition, inhibiting the occurrence of faults from the source. The shell of the high-capacity transformer has a very high level of protection, which can cope with all kinds of extreme weather and block external pollutants.

Lugao 132kv 110kv 50mva 125mva Oil immersed transformer Operating Environment

1.   Standard operating temperature: -30℃～+40℃, if it exceeds the standard, you need to negotiate with the manufacturer to install additional configuration

2.   Standard operating altitude: ≤1000 meters, when it exceeds the standard altitude, the heat dissipation efficiency will decrease with the increase of altitude, and the cooling system needs to be upgraded

3.   To avoid condensation, the relative humidity is ≤95%

4.   When installing outdoors, install a top cover according to the situation, and when installing indoors, ensure that the heat dissipation around is good

5.   Regularly check the oil level, oil quality and the condition of each component.   Ensure the efficient operation of the transformer

6.   Stay away from environments with flammable and explosive gases, away from environments with metal corrosion, and away from environments with strong electromagnetic interference
