Product Description

1.Introduction

The S11-M series fully-enclosed oil-immersed power transformer has the advantages of low loss, low noise, high efficiency, good energy-saving effect and reduced pollution. Compared with common oil-immersed power transformer, it is not equipped with oil storage cabin, the change of oil size is automatically adjusted and compensated under the elastic action of corrugated sheets of corrugated oil tank; it is isolated from air, so as to attain the purposes of preventing and relieving oil deterioration and insulation aging, enhancing operation reliability, normal running, and no maintenance.

2.Service environment

1.1  Application environment
1.1.1 Environment temperature (natural change values of surrounding air temperature)
Maximum air temperature: +40ºC
Average temperature of hottest month: +30ºC
Maximum yearly average temperature: +20ºC
Minimum air temperature: -25ºC (for outdoor transformer)
Minimum air temperature: -5ºC (for indoor transformer)
1.1.2 The altitude height of installation location shall not exceed 1000m. If exceeding 1000m, it's necessary to otherwise specify.
1.1.3 The relative temperature of air is not higher than 90% (when the air temperature is +25ºC).
