Product Description

 

Product Introduction

Oil immersed series transformer:

   

      The M in S11 (M) R- indicates that the tank is fully sealed, and the fully enclosed distribution transformer eliminates the oil tank in the case of a conventional oil immersed transformer.
     
       The three-phase oil immersed distribution transformer produced by our company adopts a new insulation structure, which improves the ability to withstand short circuit. 
     
       The core is made of high quality cold rolled silicon steel sheet. High quality oxygen free copper wire is used in the high voltage windingFor the material, and use a multi-layer cylindrical structure, all fasteners are using special anti loose processing.
     
       Products with high efficiency, low loss characteristics, can save a lot of power consumption and operating costs, social benefits significantly,is the country's high-tech products to promote.

Product Advantage

1.Reliable Structure

1. Using new silicon steel chip material, the service life of the transformer is longer;

2. Improved the effective support of the coil end face, stronger ability to withstand short circuit current;

3. The new hoisting structure and body positioning structure are adopted to ensure more reliable in long distance transportation and operation.
 

2. High-Quality
 

1. Our factory has a unique comprehensive testing center, and each finished transformer needs to pass the test before it can be shipped;


2. After each process in the production of the transformer is completed, we will conduct a qualified test, and the quality of the transformer has reached the highest level.
