Oil -Immersed Power Transformer

Oil-type transformers are used in power distribution or electrical substations. Their core and coils are immersed in Oil, which cools and insulates. Oil circulates through ducts in the coils and around the coils and core assembly, moved by convection. The Oil is cooled by the outside of the tank in small ratings, and by an air-cooled radiator in larger ratings.

Product Introduction

Gnee Steel (Tianjin) Co., Ltd. is one of the most professional oil -immersed power transformer manufacturers and suppliers in China. Welcome to wholesale customized oil -immersed power transformer at competitive price from our factory. Good service and quality products are available.

 

GNEE Steel oil immersed type transformer

Series oil-immersed transformer core selection of high quality high conductive magnetic grain oriented silicon steel sheet, flat stacked core structure, step type multistage joint, small no-load loss, low noise. The finished product adopts the vacuum oil injection process. The box oil storage tank adopts a fully sealed structure, the insulating oil and insulation medium do not contact with the air, and the oil change is not needed under normal operation, the maintenance cost of the transformer is reduced and the service life of the transformer is extended. This series of products have a beautiful appearance, excellent performance, maintenance-free, reasonable structure, advanced technology, stable and reliable product performance and other characteristics, has been widely used in the power grid.

Oil-immersed Electrical Transformer Performance Characteristics

1. The high-pressure winding all adopts a multi-layer cylindrical structure, which improves the impact distribution of the winding.

2. The low-pressure winding adopts cylinder or spiral structure, with high mechanical strength, Ann turn balance, and good short-circuit resistance of the product.

3. The positioning structure is added to the device body, so that no displacement is generated during transportation. Meanwhile, all fasteners are equipped with fastening nuts to ensure that the fasteners are not loose in the long-term operation process and meet the requirements of not lifting the core.

4. Spray primer and finish paint after oil removal, embroidery removal and phosphorization treatment, which can hide the special use requirements of metallurgy, petrochemical system and wet and dirty areas.

5. Select the components, adopt the fully sealed transformer oil tank, with the pressure release valve, signal thermometer, gas relay installed according to the standard requirements, to ensure the safe operation of the transformer.

6. This series of products are beautiful in appearance, small in size, can reduce the installation area, is ideal maintenance free products.
