Oil Immersed Transformer Introduction

 

Oil Immersed Transformer is manufactured in conformity with IEC60076 standards (applicable International Electrotechnical Commission standards) and GB1094 standards (applicable state standards of the People's Republic of China). This series of transformers features excellent impact resistance, high mechanical strength, strong short circuit resistance, low partial discharge, low noise, nice sealing performance and less maintenance. It is widely used as the main transformer in power stations, transformer substations and power transmission and transformation systems of urban and rural power grids.

Main measures for preventing oil leakage:


1. Superior large-width steel plate is selected as material and no vertical joins on the tank wall.


2. All sealing flanges are products of finish machining, thus to ensure components' flatness and cleanness. Therefore, the sealing parts have very long service lifetime.


3. Dual-sealing structure is adopted for large and medium size tank, thus to further ensure tank rim from oil leakage.


4. Advanced technology is adopted during protective welding, thus fully ensuring the welding quality. X-ray leakage detection is carried out for each welding seam.


5. All main components and parts (for example, bushing, radiator, sealing parts, butterfly valve and flap door) are purchased from the famous manufacturers recognized and certified by authority.
