High Voltage Distribution Transformer 150kVA

Features of products
    The three-phase oil-immersed distributing transformer applies new type insulating structure and makes short -circuit resistance strong. The iron core is made of high-quality cold-rolled silicon-steel plate. High-voltage winding group is made up of high-quality oxygen-free copper lines and it adopts multilayered drum typestructure. All fasteners have been processed with special treatment to prevent them from loosening.
    As high-tech product that promoted by the country, the product has many advantages such as highefficiency, Iow loss.Its social benefits are remarkable that it will save much of electricity consumption andoperating cost.
 
Reliable structure
    With the fundament of traditional frames and proved techniques, our company made a great improvement,for instance:
    we employ spiral loops with longitudinal oil path to produce a better interior cooling effect;
    we improve the effectual support of the loop's terminal face to strengthen the anti-short circuit electricity capability;
    we employ new suspending structure and instrument-positioning frames to guarantee that the long distance transport and movement will be more reliable.
    In addition to those above, we have lots of novel and dependable frames that wait to serve you.
    We are sure that, when you choose more advanced transformers, you will enjoy greater technique intensity.
 
Excellent materials
    Because we use oxygen-free copper lines of lower resistivity, which will become smoother and burr-free after series of additional surface treatment, so the load loss of our transformer is lower and the electric performance is better.
    We use high-quality silicon-steel plates which are of lower unit loss, and the no-load of the transformers is lower.
    We use high quality wooden laminating insulation pieces, which won't split or move even under the influence of short circuit.
    We use thoroughly filtrated transformer oil containing less water, gas and impurities, which makes our transformers work better.
    We use high quality rubber sealing material, which can prevent the transformers from aging or leakage.
    All raw materials has passed the quality testing, and all the raw material factories has pass through the national standard ISO9000 inspection.
 
Good technology and economic performance
    Compare with S7 series product, S9 series product reduces the no-load loss by 10%, load loss by 24% and no- load electric current by 46%; as a result, the operating cost will drop by 19%.
    Improved from S9 series product, Sll series product reduces the no-load loss by 30%; no-load electric current by 70-85%; average temperature by 10K; noise level by 2-4 db; and double the products' service life. Even under 20% overloads, it can also work for a long period of time.
 
Sealed tank(M)
    The "M" in S11 (M) R- stands for omniseal structure that the oil tank employed. Compared with common oil-immersed transformer, omniseal oil-immersed transformer taking off oil storage cabinet adopts wing-like corrugation for replacing oil tube as component of heat dispersion. The corrugated oil tank which is made up of high-quality cool-rolled plates isproduced on the special produce lines. The wing-like corrugation will expand and compressas that the volume of transformer dose, so that the transformer is separated from the atmosphereand can prevent or slower deterioration of oil and breathing of insulation. All these ensure the reliability of operation and without maintenance.
    After the treatment of deoiling, derusting and parkerizing, the surface of corrugated oiltank is coated with paint which can provide rain-proofing, damp-proofing and salt haze-proofing. It is suitable for the use in the environment, such as metallurgy, petrochemical industry and mining, etc.
