Product Description


S11-M oil immersed power transformer


The reel core fully sealed distribution transformer is a new generation of low noise and low loss transformer developed in recent years. Its iron core has no joint, greatly reduces the no-load loss and no-load current, reduces the no-load current by 60%~80%, the high and low coils are continuously coiled on the core column, the winding is tight, the concentricity is good, and the product is enhanced more. Anti-theft performance. The noise decreased by more than 10 decibels. The temperature rise is low 16-20K. Because of the continuous winding of iron core (cross section is pure circle), the orientation loss of silicon steel sheet is fully utilized, and the no-load loss is reduced by 20%~30%.

Compared with S9 transformer, the S11 transformer reduces the no-load loss by about 30%.
The low voltage winding with capacity in the 630~2500kVA enclosure is made of cylinder or spiral structure with high mechanical strength and balanced ampere distribution. The product has good short circuit resistance.
The positioning structure is added to the body so that it does not produce displacement during the transportation process, and all fasteners are equipped with fastener nuts to ensure that the fasteners are not loose during the long run of the product and meet the requirements of the non core lifting.
The corrugated oil tank is adopted in the transformer, and the oil conservator is cancelled, the box cover and the box edge are completely welded or fastened by bolts, thus prolonging the service life of transformer oil.
The product surface is painted, primed and topcoat after degreasing, rust removing and phosphating. It can meet the special requirements of metallurgy, petrochemical system and wet dirty area.
A fully sealed transformer oil tank is used. The pressure release valve, signal thermometer and gas relay are installed according to the standard, so as to ensure the safe operation of the transformer. This series of products has beautiful appearance, small size, and can reduce the installation area. It is an ideal free maintenance quality product.

Company introduction

Qingdao Hengfengyou group specializes in the development research, manufacturing and service of power transformers for 30 years. At present, the company has 10 senior engineers, 30 senior technicians, more than 200 employees, with an annual output value of 50 million US dollars and an annual production capacity of more than 10 million kVA. Hengfengyou is a large-scale enterprise in the field of power transmission and distribution equipment manufacturing. With high-quality products and perfect service system, It now provides reliable power transformer products and services for more than 50 countries and regions around the world. It has established a good reputation and image of "HFY" brand in the global market, and won extensive trust and praise from customers.


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.
