2.5 Mva Dry Type Transformer Price

2.5 mva dry type transformer price: USD1*352.00/set

Dry-type transformer is the abbreviation of a transformer that adopts a dry-type iron core or copper core stacked structure (ie, ferromagnetic resonance) and uses air as a cooling medium.

It has the characteristics of small size, light weight, low loss and low operating temperature, so it is widely used in power systems.

The 2.5 mva dry type transformer belongs to the medium-capacity series. Its rated voltage is 400/500V and its rated current is 12A. It is suitable for 10~40.5Kw three-phase AC power supply and used for step-down. This series of transformers consists of a shell, windings and heat sinks. The windings include: a cylindrical coil rolled from a silicon steel sheet, and an enameled wire around it. The cooling device includes: a radiator and a fan.

Features of 2.5 mva dry type transformer:

1. Small size and light weight:

Due to the stacked structure of dry iron core and copper core (that is, ferromagnetic resonance), its overall size is much smaller than that of an oil-immersed reactor with the same capacity, and its weight is also much lighter.

2. Low loss:

Due to the air-cooling method, its loss is about 10% lower than that of an oil-immersed reactor.

3. Low noise:

Since there is no oil tank, the noise it generates is 20% lower than that of inductive inductors with oil tanks.

4. Long life:

Due to the tankless design and the materials used, it has a service life of more than 10 years.

5. Wide working temperature range:

Because it is cooled by forced convection of air, it can operate at temperatures as high as 40°C.

6. Strong adaptability:

For power supplies of various frequencies, it can be used.

7. Less maintenance workload:

Because it has no fuel tank and oil passage, there is no need for regular inspection, just pay attention to clean the dust.

Technical requirements for 2.5 mva dry type transformer:

1. The shell shall meet the following requirements:

(1) Material: Q235 steel is used between the outer casing and the inner casing, and No. 45 steel is used between the inner casing and the outer frame. Sealing ring: rubber parts, temperature resistance 105°C.

(2) Shell: smooth surface, uniform color, no scratches, and no scars that affect the use; all joints should be tightly connected; serious corrosion is not allowed.

2. Winding installation:

Arrangement order of windings: primary first, then secondary, high voltage first, then low voltage.
