General
The SFZ series Oil-immersed type transformer features low noise, low loss, rational structure, high quality material, scientific design, strict production technology and advanced test method.
The product also has the following additional advantages:
1. High mechanic strength, great anti-short circuit capability, excellent anti-lightning impulse capability and high reliability. All these performance indexes rank first in the industry in China.
2. Excellent overload capability, capable of continuously working under 110% rated load.
3. Low loss, energy-saving, economic and maintenance free.
4. Nice appearance, small size, less installation space occupation and low engineering cost.
5. Each performance index and technical specification excels that specified in China GB, international IEC and industrial standards.
6. Hermetically sealed corrugated tank structure is adopted, thus to effectively prevent air corrosion to the oil and prolong service lifetime of the transformer.
