33KV oil immersed transformer

33kV series oil immersed power transformer is advanced in design, and greatly improved in material, structure and technology. Showing strong short-circuit resistance, beautiful appearance, reliable operation, low loss and low noise, it’s performance reaches the advanced level of global similar products.

This product conforms to the Chinese national standard GB1094.1-2013 <power transformer> and GB / t6451-2015 <three phase oil immersed power transformer technical parameters and requirements>. This product has adopted a series of major improves in material, technology and structure, so that the electrical performance of the product reaches the international advanced level compared to similar products. With the characteristics of high efficiency and low loss, it can save lots of power consumption and operation costs, thus has obvious energy-saving effect. It is a new product promoted by the state and one of the most popular products for users.


35 KV oil immersed transformer

Compared with S9 series, the no-load loss of S11 series products is reduced by 30% on average, and no-load current is 70-80% lower. The iron core is made of import high magnetic conductivity, low loss, cold-rolled high-quality silicon steel sheet, which reduces the no-load loss and saves energy significantly. It shows characteristics of high safety and reliability, advanced structure, small dimension, light weight, low noise, low temperature rise, anti-corrosion and reliable anti-leakage measures to prevent oil leakage.




Hengfengyou transformer Qingdao branch is one of the holding subsidiaries of "Qingdao Hengfengyou group". It has been specialized in the development research, manufacturing and service of power transformers for 30 years.


Our main products are: oil immersed transformer, dry type transformer, amorphous alloy transformer, experimental transformer, electric furnace transformer, rectifier transformer, etc. At present, our 10kV, 12kV, 20kV, 33kV, 35kV oil immersed transformers of S11, S13 series , 10kV, 12kV, 20kV, 33kV, 35kV epoxy cast dry-type power transformers of SCB10, SCB13 series , SH15, SCBH15 amorphous alloy power transformers, on load tap changing transformers and other products have passed the inspection of the national electrical product quality supervision and inspection agency and obtained the registration model record certificate. The products also passed the energy efficiency product certification of China quality certification agency, CCC product certification of national power certification agency, EU CE certification, ISO9001 quality management system certification and so on.


Our company research and development production of S11 - M series fully enclosed oil-immersed power transformer has the advantages of low loss, low noise, high efficiency, can obtain good energy saving effect and reduce pollution. Totally enclosed compared with ordinary oil-immersed transformer, cancelled the oil storage tank, the oil volume change by corrugated tank elastic corrugated chips to automatically adjust the compensation, transformer isolated from the rest of the air, to prevent and slow the deterioration of oil and insulation aging, improve operational reliability, running free maintenance.
