Power transformer S series

immersedindustrialtelecommunications

Overview The oil immersed power transformer is composed of core, coil, voltage regulating switch, oil tank and other components, and the dielectric material is dielectric oil. Description  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. Features： Core 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 current. Coil 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.
