On the basis of the S9 series, the S22 power transformer has a 30% reduction in no-load losses, a 70-85% reduction in no-load current, a 10K reduction in average temperature, and a longer service life. The S22 power transformer is more than doubled, and even at 20% load, the product can operate for a long time, and the average noise level of the product can be reduced by 2-4 decibels.

The oil volume of the S22 power transformer can expand and contract, and at the same time, the transformer is protected from the atmosphere, avoiding reducing oil deterioration and insulating moisture, improving operational reliability, normal operation and maintenance-free. After deoiling, rust removal and pickling phosphating, the surface of the carton is coated with three layers of anti-paint, which is suitable for metallurgy, petrochemical, mining and other environments.

Construction & Advantages:

A. The low-voltage winding of the oil-immersed transformer generally adopts a cylindrical or spiral structure; The high-voltage winding adopts a double-layer cylindrical structure, with balanced amperage and winding turns, small magnetic leakage, high impact toughness, and strong short-circuit resistance.

B. The core and winding resistance are individually tightened. Both the body height and the tightening part of the low-voltage conductor are equipped with self-locking locknuts. The non-suspended structure is selected to withstand the impact of transportation.

C. The fuel tank is made of corrugated plate, which has a breathing function and can compensate for the change of oil quantity caused by temperature changes. As a result, the product does not have a tank, which significantly reduces the transformer height.

D. Because the corrugated plate replaces the storage tank, transformer oil and external protection, it effectively avoids the reduction of insulation performance caused by oxygen and water ingress.

E. After deoiling, embroidery, phosphating, the surface of the product is sprayed with primer and topcoat, which can meet the special requirements of metallurgy, petrochemical system, wet polluted area.

F. Install the selected components according to the specifications and standards, such as sealed transformer oil tank, pressure release valve, signal temperature gauge, gas relay, etc., to ensure the safe operation of the transformer.

The S22 power transformer is beautiful in appearance and small in size, which can reduce the installation area. The S22 power transformer is an ideal maintenance-free, high-quality commodity.

Product Advantages:

The S22 power transformer produced by our company adopts a new insulation structure, which improves its short-circuit resistance; The core is made of high-quality cold-rolled silicon steel sheet; The high-voltage winding is made of high-quality oxygen-free copper wire, and the double-layer cylindrical structure is selected; All firmware parts are selected.

S22 power transformer has the characteristics of high efficiency and low loss, which can save a lot of power consumption and operating costs, and has obvious social benefits, and is the promotion of new technology products in China.
