Core
All are made of high-quality grain oriented cold-rolled silicon steel sheet, with full oblique and no hole binding structure. The iron core is of multi-stage stepped shape, with three or five joints, low air loss and low noise. The rolled iron core is directly wound by special equipment, without joints and angle weight, reducing magnetic resistance and low air loss. The amorphous alloy transformer core is a kind of higher quality iron core material, with an average drop compared with the traditional silicon steel sheet Low air loss 72%, no-load current 50%.
Coil
It is made of high-quality QQ acetal enamelled round copper wire and flat copper coin drawn by oxygen-free copper rod. Its forms include cylinder type, continuous type, new spiral type, split type, etc. it has sufficient electrical strength, mechanical strength and heat dissipation capacity. In order to increase the short-circuit resistance of transformer, higher quality self-adhesive transposed conductor can be used. The coil is made of self-adhesive acetal enamelled flat wire. After being wound into a coil, the enamelled flat wires are mutually bonded to form a rigid coil, which can withstand greater bending stress, thus enhancing the short-circuit resistance of the transformer. The biggest characteristic of the self-adhesive transposed conductor is that it can reduce the loss of the transformer. Because of the multi split conductor and transposition, it can greatly reduce the eddy current loss and circulation loss, reduce the temperature rise of the hot spot of the winding, and make the temperature distribution of the whole winding more uniform.
Fuel tank
It is welded with high-quality steel plate and has elliptical and rectangular structure. The radiator element is chip radiator, expansion radiator or corrugated oil tank. The oil tank has reliable sealing test in the factory. After pickling and phos-phating treatment, the inner and outer surfaces are sprayed with three times of primer and one time of finish paint. The product is salt fog proof, damp heat proof and mould proof, which can meet the requirements of metallurgy, petrochemical system and humidity, special requirements for polluted areas, beautiful and reliable operation.
