As a kind of clean energy, electricity has become the main driving force of the development of the times, whether it is industrial production or transportation are vigorously promoting the application of electric energy. Especially in the current situation of environmental degradation, to replace traditional energy sources with electricity has become an urgent matter. The application of electric energy can not be separated from a variety of transformers to assist, transformers according to its cooling method is mainly divided into dry-type transformers and oil-immersed transformers. Dry-type transformer mainly rely on air convection for natural cooling or increase fan cooling, so more for building electricity and local lighting and other small capacity transformer place. Oil-immersed transformers rely on oil as a cooling medium, strengthening the insulation and cooling conditions, is widely used in industrial and mining enterprises, petrochemical industry and large buildings and other power distribution places.

When the market oil-immersed transformer models, performance characteristics are very different, how to choose a reliable quality, easy to maintain the product has become a headache for many power supply units. Green Apple Transformer as the industry’s transformer suppliers, the launch of the S11 and S13 oil-immersed power transformers with innovative technology and quality to win the market’s welcome.

Green Apple S11-M series fully sealed oil-immersed transformer has the advantages of low loss, low noise and high efficiency, which can achieve good energy saving effect and reduce pollution. Fully sealed transformer compared with the ordinary transformer, eliminating the oil storage cabinet, oil volume changes by the corrugated mailbox corrugated piece of elasticity to automatically adjust the compensation, the transformer is isolated from the air, to prevent and slow down the deterioration of the oil and insulation aging, enhance operational reliability, normal operation maintenance-free. Green apple S11-M series transformer mainly has the following characteristics: 1, transformer core is made of cold rolled silicon steel sheet stacking, greatly reducing no-load loss and no-load current, and the core is tied to ensure that the core of the tightness of the noise reduction. 2, high and low voltage windings are wound with oxygen-free copper, low voltage windings of 500kVA and the following double-layer cylindrical structure, 630kVA and the above using foil type coil, high-voltage coil adopts multi-layer cylindrical structure. 3, transformer linkage group adopts Dyn11, reduce the harmonic impact on the grid, improve the quality of power supply. 4, the transformer is fully sealed structure, prolonging the service life, free of lifting heart, free of maintenance. 5, measured noise value is lower than the standard.

The innovative technology application of Green Apple’s S11 and S13 oil-immersed transformers provides a more reliable solution for power supply units to build distribution networks. The advantages of low loss, low noise and high efficiency of its products have made the Green Apple oil-immersed transformer a popular and classic product in the industry.
