20kVA 10kv Wond Core Type Hermetically Sealed Oil Immersed Transformer/Distribution Transformer

Introduction:

Load regulating power transformer is developed and produced according to the requirement of the market. It

can be widely used in urban & rural, industrial & agricultural power network, which has a great significance for

energy-saving and environment protection. The lamination method of this product’s iron core is ladder form,

instead of the traditional iron core lamination technology, which improves the magnetic circuit distribution inside

the iron core. It can be seen as a revolution of transformer iron core manufacturing. Compared with the

traditional, the no-load loss, no-load current and noise of the new one decrease 20% respectively, and load

loss decreases 10%. The new product applies CAD, with advance design, reasonable structure, and excellent

materials. Each index complies with the standards of GB1094-1996 “Power Transformer” GB/T6451-1999

“Technical Parameters and Requirements of Three-phase Oil-immersed Type Power Transformer”. Now its level

is the leading position of our country.

The hermetically sealed oil transformers are normally manufactured with a sealed tank equipped with fins that allow the expansion at the temperature variations. The tightness of the tank is up to 0.5 Bar. This type of transformer is the most widely used in the world. In the hermetically sealed transformer, the oil does not come into contact with the air and its electrical properties are therefore not compromised, ensuring a long life span of the transformer. For powers exceeding 3150kVA, or in case of a transformer with radiators, the transformer can still be hermetically sealed by means of a nitrogen cushion.

For this type of transformers the expansion of the insulating liquid is compensated by the elastic deformation of the oil-cooling radiators attached to the tank. The protection against internal faults is ensured by means of a DGPT device: Detection of Gas, Internal Over Pressure and Oil Over Temperature.

Features:

High reliability, advanced level of performance, economic indicators and reasonable;

Using phase-shaped core of three joints, curing paint brushing the surface to reduce wear and tear and noise;

Winding structure of a new oil road design is reasonable, with the new insulation to improve the mechanical

strength and the ability to engage in short-circuit;

Tank forms, beautiful, generous.

It can be widely used in urban power network as well as petrochemical, metallurgical, textile and humid,

inaccessible enterprises, and mining.
