Introduction

 

  • S11 Series Three-Phase Variable Voltage Transformers offer better energy efficiency and longer lifespan compared to the S9 series.
  • Non-Standard Customization: Rated capacity ranges from 200 to 2500 KVA.

 

We have made several improvements based on traditional structures and mature technologies, including:

  • Spiral coils with longitudinal oil channels for better internal cooling.
  • Enhanced support for coil end-faces, increasing short-circuit current resistance.
  • New lifting and positioning structures to ensure reliability during long-distance transport and operation.
  • Many unique and reliable structures to serve you.
  • Higher-performance transformers with advanced technology.

 

The S11 series offers significant improvements over the S9 series:

  • No-Load Loss: Reduced by an average of 30%.
  • No-Load Current: Decreased by 70-85%.
  • Average Temperature Rise: Reduced by 10K.
  • Product Lifespan: Increased by more than twice, allowing for long-term operation even under 20% overload conditions.
  • Operational Noise: Reduced by an average of 2-4 decibels.

 

In December 2022, we welcomed an important client from a city in Brazil, Pietro, through our independent platform. Pietro's city is undergoing rapid development with a growing demand for electricity. After extensive market research and comparisons, he finalized a custom solution for a 300KVA S11 oil-immersed distribution transformer. During the discussions, Pietro had strict requirements regarding the product's performance, quality, and reliability. Our sales team and technical experts responded proactively. The successful collaboration with Pietro not only expanded Jinshanmen Technology Co., Ltd.'s presence in the international market but also established a strong reputation for the company in Brazil and across South America.

The typical service life of an S11 300KVA oil-immersed distribution transformer is between 20 to 30 years. However, its actual lifespan can be influenced by various factors, such as operating environment, load conditions, quality of maintenance, and power grid stability. If the transformer operates in a favorable environment, with moderate load, proper maintenance, and a stable power grid, its lifespan may approach or exceed 30 years. Conversely, if it is exposed to harsh conditions (high temperatures, humidity, dust, etc.), operates under overload, or lacks proper maintenance, its lifespan may be significantly reduced.
