500kVA tunnel engineering mobile substation( EU cooperation products)

1. High Reliability By adopting the special VPI (vacuum pressure impregnation) technology and excellent NOMEX® insulation paper, the product shows good overall temperature and humidity resistance as the compact NOMEX® insulation paper still keeps 90% of dielectric strength under complete drying when the humidity is 95%, and good radiation resistance as the product still has original electrical performance and mechanical property in the event of 800 Mrad ionizing radiation.

2. Strong Overload Capacity Because of using NOMEX®paper as a major insulation material, the product has large heat-resistant margin. NOMEX® paper belongs to C-class insulation, and can work safely and stably under 220°C for a long term. Designed as H-class insulation, the product’s maximum operation temperature is 180°C, therefore, 40°C heat-resistant margin will ensure the transformer to work safely even under the circumstances of higher air temperature, more harmonic components and short running beyond installed capacity.

3. Good Environmental Protection, Low Noise NOMEX® paper will endure a short running at 350°C, and cannot soften, fuse and support combustion at 250°C. It will not send out toxic or corrosive gas even at the temperature of 750°C, and never embrittle at an extremely low temperature. The iron core is made out of imported high-quality oriented silicon sheet under optimized design, so the noise will be controlled within 48dB, and the environmental performance is excellent.

4. Good Electrical Performance and Small Partial Discharge

Yes,we can provide sample with charge.

2. What is Amorphous Alloy?

An amorphous metal (also known as metallic glass or glassy metal) is a solid metallic material, usually an alloy, with a disordered atomic-scale structure. Most metals are crystalline in their solid state, which means they have a highly ordered arrangement of atoms.Amorphous metals are non-crystalline, and have a glass-like structure. But unlike common glasses, such as window glass, which are typically electrical insulators, amorphous metals have good electrical conductivity.

3. Advantages of Amorohous alloy

The amorphous is more superior to traditional silicon steel sheet in magnetic permeability, excitation current and iron losses, especially in iron losses, only 1/3 to 1/5 when compared with silicon steel sheet.

1. Small space occupy and easy installation. 2. Low loss 3. Better efficiency in power using 4. Long service time 5. Wide application range.

4.Do you take special orders ?

 Yes , We accept customized products.
