11kV - 800kVA , Oil - Immersed Transformer, Three Phases, Two Winding, Power Distribution
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.
high quality cold rolled grain-oriented silicon steel
high quality copper conductor
high quality foil conductor
The transformer adopts class-A insulation.
The tank is jointed with high-quality steel.
The transformer is equipped with HV & LV bushings, oil drain valve, earthing bolt, lifting board, rating plate, pressure relief valve and other accessories. Transformers of over 800KVA power are equipped with signaling thermometer and gas relay.
---This indicator can give the correct oil level 30mm under the oil tank cover.
Indication is real,correct.The position of oil indicating can be decided by our
customers' requirements, and is given it out when they order the goods, without
special requirements the oil level indicating position will be set above the tank cover,
i.e. when the oil level is above the tank cover, float gives blue color completely,that
means the oil level is OK.
