The body of the S13-2000KVA oil-immersed power transformer adopts a new insulation structure to improve the anti-short circuit ability; The windings are made of high-quality oxygen-free copper wire, and a multi-layer cylindrical structure is adopted; All fasteners are treated with special anti-loosening treatment; The S13-2000KVA oil-immersed power transformer adopts corrugated oil tank and fully sealed structure, so that the S13-2000KVA oil-immersed power transformer is isolated from the atmosphere, prevents and slows down oil deterioration and insulation moisture, enhances operation reliability, and operates maintenance-free.

Key functions and features:

1、 Core: The core of S13-2000KVA oil-immersed power transformer is made of cold-rolled oriented silicon steel sheet with a thickness of 0.30mm or 0.27mm, and the step-type coiled core is made of a jointless structure, which is rolled on the core winding machine, first winding 2 small frame cores, and then rolling a large frame outside the 2 small frame cores to form a three-phase coiling core, after the completion of the rolling, it is then loaded into the core annealing furnace, and the core performance can be fully restored after vacuum and nitrogen annealing, therefore, the no-load loss of this series of S13-2000KVA oil-immersed power transformers is very lowThe no-load loss of S13-2000KVA oil-immersed power transformer is reduced by 30% on average compared with the S9 series 10KV distribution S13-2000KVA oil-immersed power transformer, which is a better low-loss distribution S13-2000KVA oil-immersed power transformer.

2. Coil: The coil winding of the coiled core S13-2000KVA oil-immersed power transformer needs to use a special winding machine, which is directly wound on the core, and the high and low voltage coils are wound at the same time, and there is no need to use the winding die.

3. Assembly: When assembling, it is no longer necessary to disassemble the iron yoke on the core, which can prevent the increase of the core loss in the assembly process.

4. Fuel tank: The fuel tank of the S13-2000KVA oil-immersed power transformer for coil distribution is all corrugated fully sealed.

The performance data of S13-2000KVA oil-immersed power transformer such as no-load loss and load loss are completely consistent with the performance data of -M.R series 10KVS13-2000KVA oil-immersed power transformer.

S13-2000KVA Oil-immersed Power TransformerS13-2000KVA Oil-immersed Power Transformer can convert the grid voltage into the voltage required by the system or load to realize the transmission and distribution of electric energy. This S13-2000KVA oil-immersed power transformer can replace the S13-2000KVA oil-immersed power transformer with silicon steel sheet and iron core, and is widely used in outdoor power distribution system.

The large number of network operation of this product can be desirable for good energy-saving effect and can reduce air pollution. This product is particularly suitable for areas where there is a shortage of electrical energy and large load fluctuations, as well as areas where routine maintenance is difficult. Because the S13-2000KVA oil-immersed power transformer adopts a fully sealed structure, the insulating oil and insulating medium are not subject to atmospheric pollution, so it can operate in a humid environment, and is an ideal power distribution equipment in the vast distribution network in urban and rural areas.

The core of the S13-2000KVA oil-immersed power transformer is made of amorphous alloy strip, which has the advantage of low no-load loss. The no-load loss is about 65% lower than that of the S13-2000KVA oil-immersed power transformer. It is a national second-class energy efficiency product.

Copper foil coil is used for low voltage to enhance the ability of S13-2000KVA oil-immersed power transformer to withstand short circuit; Dyn11 is used in the coupling group to reduce the influence of harmonics on the power grid and improve the quality of power supply. The fully sealed structure of the fuel tank and the tank cover welding as one prolongs the service life and is maintenance-free; The S13-2000KVA oil-immersed power transformer adopts vacuum drying and vacuum oil injection, which can completely remove air bubbles in the coil and ensure stable insulation performance.
