20kV - 1600kVA , Oil - Immersed Transformer, Three Phases, Two Winding, Power Distribution

 

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.
 

 

Accessories:


The transformer is equipped with HV & LV bushings, oil drain valve, earthing bolt, lifting board, rating plate, pressure relief valve and other accessories. Transformers of over 800KVA power are equipped with signaling thermometer and gas relay.

 

 

2.Structure and feature

 

2.1 Tubing oil level indicator consists of the instrument housing made of aluminum

alloy which is shaped by compressing and casting,float indicating system,protective

frame,visual window and top cover or pressure-relief-valve;Visual window is made

of thick glass tube which is inside the indicator.
