Details: S Series of Oil-Immersed Transformers are suitable for use both indoors and outdoors at ambient temperature up to 50º C. With reasonable structure, the transformer is capable to withstand short-circuit and overload, having many good features, such as free of maintenance and easy to repair.
Core is designed into oval-shape and laminations jointed together in 45° Mitred at 4-step-lap, which gives a compact space factor for reducing no-load losses. The whole process is controlled by computer. Upper yoke is free of stacking which ensuring the core free from being damaged when assembling and disassembling the yoke from limbs.
Both HV and LV windings are designed in Layer and Cylindrical Structure. Instead of corrugated pressboard, high fire-resistant laminated-wood rods are used to form oil-ducts which are easier for oil circulation and to speed up dissipating winding heat for improving and having higher overload capacity. The LV winding of 250kva and above is made of imported copper foil. Winding layers, insulation is made up of diamond dotted paper, which is glued with all windings into an entirety after hot drying. This helps to strengthen the winding mechanism ability, which increases stronger capacity to withstand shot-circuit.
All wiring are connected in a flexible way, so they would not loose or be broken during transportation. The height of an active part is changeable with bolts and rubber under bottom. The active part would not be displaced during transportation, thus the product is reliable.
