S(B) Oil-immersed Transformer

A transformer specially designed to improve electrical performance and durability is manufactured using high-quality materials and process technologies. The transformer realizes the uniform distribution of the electric field through the copper foil winding technology of the low-voltage winding, thereby optimizing the electrical efficiency. In terms of the internal structure, the low-voltage part uses a formed hard paper tube as the inner frame and is equipped with laminated wood compression blocks to enhance the overall mechanical strength and stability. In terms of the production process, the transformer is treated with a vacuum oil injection process, which can effectively eliminate the bubbles inside the coil and further improve the electrical performance and insulation grade.

Product Features

  1. Easy to maintain: The design of this transformer focuses on the simplicity of daily maintenance to facilitate effective management and maintenance by users.

  2. Appearance and detail processing: The edge of the box body is connected with stainless steel bolts, which not only guarantees the mechanical strength but also takes into account the beautiful appearance.

  3. Reliable sealing components: The sealing parts are molded parts, making the overall sealing of the transformer better and reducing the risk of failure caused by sealing problems.

  4. Vacuum oil injection process: The transformer is oiled under vacuum conditions to completely discharge the gas inside the coil to ensure good insulation performance and reliable long-term operation.

  5. Copper foil winding technology: The low-voltage winding is precisely wound with copper foil to ensure the balanced distribution of the electric field inside the transformer, reduce the risk of local overheating, and improve the power transmission efficiency.

  6. Mechanical structure strengthening: The inner frame is composed of a formed hard paper tube, which is not only light in weight but also high in strength; the compression block uses laminated wood material, increasing the anti-vibration and durability of the transformer during operation.

  7. Fully sealed oil tank design: The product is equipped with a fully sealed oil tank, which effectively isolates the transformer oil from contact with the outside air, greatly slowing down the natural aging speed of the transformer oil and prolonging the service life.
