hermetically sealed oil filled transformer
Product Introduction
Hermetically Sealed oil-immersed transformer is a type of power equipment that is designed with a special structure to achieve internal sealing. Its core characteristic is that the internal substances (such as oil, gas, etc.) are completely isolated from the external environment during operation. This type of transformer utilizes a rigid shell or elastic material compensation device to ensure that the total volume of the internal medium remains constant under different temperature conditions, thereby avoiding oxidation and pollution problems caused by 'respiration' in traditional transformers

The main advantages :
Insulation and Protection：The fully enclosed structure effectively isolates oxygen and moisture, significantly reducing the risk of insulation material moisture and oxidation, and extending its service life.
operational reliability：The sealing design reduces the contact between oil and air, avoids the invasion of pollutants, and improves the stability of equipment operation, especially suitable for industrial scenes with dense dust or large humidity fluctuations.
safety：By isolating the oil gas contact interface, the risk of combustible gas explosion is significantly reduced.
Structural characteristics: Adopting rigid body sealing structure or elastic compensation device, the total volume of internal oil, gas and their mixtures is kept stable at different operating temperatures through mechanical design. This design completely blocks the material exchange channels inside and outside the transformer, eliminating the phenomenon of air intake caused by thermal expansion and contraction in traditional breathing transformers.
