Introduction

 

Oil-immersed type transformer features low noise, low loss, rational structure, high quality material, scientific design, strict production technology and advanced test method. The product also has the following additional advantages:


1. High mechanic strength, great anti-short circuit capability, excellent anti-lightning impulse capability and high reliability. All these performance indexes rank first in the industry in China.


2. Excellent overload capability, capable of continuously working under 110% rated load.


3. Low loss, energy-saving, economic and maintenance free.


4. Nice appearance, small size, less installation space occupation and low engineering cost.


5. Each performance index and technical specification excels that specified in China GB, international IEC and industrial standards.


6. Hermetically sealed corrugated tank structure is adopted, thus to effectively prevent air corrosion to the oil and prolong service lifetime of the transformer.

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.


6. Superior sealing part and nitrile rubber are adopted for sealing process. The nitrile rubber is a type of oil-resistant high-elasticity product that has a reputation as "sealing expert".
