three phase oil immersed transformer,
oil immersed distribution transformer
The oil immersed power transformer is used for regulating voltage and AC power transmission. The advantages include small dimension, reasonable price, strong weather resistance and so on. It is applicable to power systems, industrial and mining enterprises, transportation, post and telecommunications sector, research institutes, etc.Smart and diverse structures and nice appearance make this product to meet the needs of different users.
High-quality grain-oriented cold-rolled silicon steel sheet are employed, and the whole oblique non-porous
banding structure are used here. The core has a multi-level ladder shape, with three joints or five joints, which
is of low no-load loss and low noise. Rolled cores are direct rolled by certain special equipment, which gives the
advantages including no seam, no corner weight, reluctance reduction, low no-load loss. Amorphous alloy is an
advanced core material, which leads to an average reduction of 72% no-load loss and a reduction of 50% no-load
The high-quality QQ acetal enameled round copper wire and oxygen-free copper rod are used to form the coil.
The coil type includes cylinder type, continuous type, new type spiral type, split type, etc. It has sufficient electrical
strength, mechanical strength and cooling capacity.
In order to increase the capacity of anti-short-circuit of the transformer, self-adhesive transposition wire is used in the
35kV and above windings. The wire is made of self-adhesive acetal enameled flat wire, and after winding into a coil,
it is heated so that the flat wire could be bonded between each other to form a rigid coil, which can withstand greater
bending stress, thereby enhancing the capacity of anti-short-circuit of the transformer. The most important feature of
the self-adhesive transposition wire is that it can reduce the loss of the transformer, and as a result of multi-stranded
conductor with transposition, the eddy current loss and circulation loss are greatly reduced, it can also reduce the
temperature rise of the partial hot spots of winding, thus the winding temperature distribution is more uniform.
The oil tank is made of high quality steel plate, and the shape includes elliptical shape, rectangular shape, etc.
The type of the radiator includes: corrugated sheet type radiator, expansion type radiator and corrugated type tank.
The sealing performance test is conducted on oil tanks. The inside and outside surfaces are pickling and phosphate
treated, and then spray priming paint for three times and surface paint for one time, which give its corrosion resistance.
