Product Overview
The 2000 kVA dry type transformer is a small, three phase, oil free, fireproof, and environmentally friendly distribution transformer with epoxy resin casting insulation. High mechanical strength: The filler filled resin results in a small difference in the coefficient of expansion within the casting, low curing shrinkage, low internal stress, and high hardness of the cured product. Pre formed reinforcing materials are placed within the epoxy resin encapsulation layer on the inner and outer surfaces of the high and low voltage coils, creating a dense structure similar to reinforced concrete. Therefore, its mechanical strength is even greater than that of pure epoxy resin, enabling it to withstand sudden short circuit electrodynamic forces without damage.
2000 kVA dry type transformers have a wide range of applications: step down transformers meet various voltage conversion needs, can be used in small transformer systems for lower capacity applications, or as three phase distribution transformers in industrial power systems. Thanks to their reliable performance, standardized design, and mature standardized production, we maintain a reasonable inventory level for immediate delivery. We manufacture in strict accordance with multiple international and regional standards: IEC, GB, JIS, ANSI, IEEE, and UL, while meeting energy efficiency ratings (Level 1/Level 2) and SCB series requirements. All products have passed rigorous testing and certification according to the relevant standards.

Characteristics |
Product Technology Advantages |
|
Low local power emission |
Using epoxy resin vacuum casting process, the partial discharge quantity is ≤5pC, which is far below the standard requirement and significantly extends the insulation life. |
|
Anti short circuit ability strength |
The coil is cast as a rigid block, which can withstand the huge electrodynamic force generated during a sudden short circuit, without the risk of displacement or cracking. |
|
Tide resistant |
It can be stored and operated in high humidity environments without pre drying; when used with a protective shell, it is suitable for dusty or corrosive environments. |
