Amorphous alloy dry type transformer is made of amorphous alloy with the structure of three-phase five-column, the core is clamped with sheet or molding frame. HV winding is adapted with the segmented hierarchical structure, meanwhile, LV winding is adapted with foil structure. Amorphous alloy dry-type transformers have many advantages as excellent energy-saving, low loss, powerful anti-short circuit capability, low partial-discharge, and low noise.
2.Rated power: 100kVA
3.Primary voltage: 33kV
4.Secondary voltage: 0.4kV
6.Vector group: Dyn11
7.Insulation class: H/F Class
1.Low loss, especially no-load loss, 70% lower than the value of GB standard, economy, and energy saving.
2.Low noise, low partial discharge, high reliability, outstanding anti-short-circuit capability, high anti-lighting impulse capacity.
3.HV winding is cast with epoxy resin at a vacuum state with pressure.
4.Simulating analysis is used in the core model to avoid the resonance and lower the noise. Simulation calculation and analysis of lighting impulse wave is also used in the HV winding model to improve anti- lightning impulse capability.

After-sales Service: We have a professional aftersales engineer team, each aftersales engineer has more than 3 years of experience. And we also have localized technical backup to offer timely support in Malaysia, South Africa, Egypt, Dubai, UAE, Brazil.
IP protective enclosure:
The standard transformers produced by our company are without the case and their protection level is IP20. We can also provide IP30 or IP40 if you require. The case can be made by common steel plates, stainless steel plants, or aluminum alloy and can be acid-washed,parkerised, and powder-painted.
The temperature controller displays are installed on the low voltage side of the case, which is reliable and convenient for users to check.
