In Wenzhou XiFa electric Power Equipment Co., Ltd, the 3 phase dry type 25 kva transformer adopts the epoxy resin vacuum casting process, which ensures excellent insulation performance, outstanding mechanical strength, as well as excellent moisture proof, arc resistant and leakage proof properties. This dry type transformer is an ideal choice for environments with high safety standards, low noise and low maintenance requirements.

Product Features:

The 3 phase dry type 25 kva transformer is based on natural air cooling , and can be equipped with forced air cooling components as needed, significantly enhancing its short term overload capacity. Special optimizations have been made for frequent fluctuating loads and harmonic conditions in scenarios such as photovoltaic and small scale wind power. It has strong anti harmonic capabilities and low additional losses. The overall mechanical structure has been reinforced with vibration damping, capable of withstanding continuous vibration and repeated current impacts. The operation is smooth during start to stop and load switching processes. The operating noise is low, and it does not cause interference to the surrounding environment.

Designing Structures to Optimize:

1. Electromagnetic Design: Utilize low loss silicon steel sheets to optimize magnetic flux density and suppress harmonic losses and moderately increase short circuit impedance to expand the efficient operating range.

2. Winding Structure: Use staggered conductors to reduce eddy current losses, and add a uniform voltage shield to balance the electric field distribution.

3. Insulation System: Select high toughness epoxy resin, strengthen the end insulation, resist repeated thermal stress, and avoid cracking.
