1. Structure of features: 

QZB autotransformer is a single-ring type transformer. shared winding and ratio is fixed. Compared to the general 

transformer of the same capacity, has simple structure, material saving advantages of small size, 

especially in occasions transformer ratio close to 1 is particularly economy. so in the voltage close to the

 high-power transmission transformer with widely used In addition,in the induction motor starter

 box more than 10kW.
2. Working conditions:
1). Altitude does not exceed 2500m.
2). The ambient air temperature:
a. the different altitudes highest air temperature 
b. Lowest air temperature: - 40 ° 
3). Air relative humidity: the wettest month average monthly maximum relative humidity of 90%, while the month's average 

monthly minimum temperature of 25 ° C, and taking into account the condensation occurs on the surface of the product due to temperature changes.
4). No significant shake and shock vibration.
5). Explosive medium, the medium does not have enough to corrode metal and damage the insulation of gas and dust (including conductive dust).
6). No rain and snow.
3. The features:
1).Energy-saving and low noise: high-quality cold-rolled silicon steel sheet, high temperature insulation material and special vacuum dipping process, the transformer more energy efficient, more quiet.
2).High reliability: reasonable structure, a lot of basic research and reliability certification in the quality assurance system and reliability engineering, 

performance indicators transformer countries fully comply with relevant standards, reliable operation, can load continuous work for a long time.
3). Environmental characteristics: heat resistance, moisture resistance, stability, chemical compatibility, low temperature resistance, anti-radiation and non-toxic.
4).Capacity: 0.5KVA ~ 5000KVA.
5).Insulation class: F class or H class.
