S11 Three Phase Oil Immersed Oil-Immersed Type Transformer Oil-Filled Electric Transformer
Coil Structure:
The high and low voltage coil is packed according to the split phase. The design pressure is
evenly compressed to ensure the coil axial strength.
The inner coil is lined with high-strength phenolic paper tube. The internal and external struts
are used on the high and low voltage coil, technically making ensure enough tightening of the
coil radial.
The exposed wires inside the transformer are insulated. Add the leading wire support point,
reinforce the strength of leading wire support frame and shell. The leading wire connection
adopts cold crimping technology.
Electrical equipment and supplies 1250kva transformer 11kv 33kv
1. The height of sea level is less than 1000m.
2. Highest temperature 40ºC
3. Lowest temperature: -20ºC
4. Maximum daily average temperature: 25ºC
5. Maximum annual mean temperature: 20ºC
6. The relative humidity is less than 95%(when the sir temperature is 25ºC)
7. Install at the site with dust methane, but no explosion water
8. Power supply voltage profile approximate to sine wave
Oil Tank Manufacturing:
Transformer tank adopts bucket type or bell-type. Model "F" is for the side blowing and
air-cooled type. The sealing rubber uses "0" type of the overall structure to ensure that
no leakage occurs.
All the gas collection pipelines on the top cover of the bell jar adopt the slope structure
leading to the gas relay.
The fuel tank takes shape by compression molding of reinforcing ribs. The cushion blocks
for the jack are 4 pieces and are marked with oil paint. The structure layout of transformer
is reasonable, beautiful. The inner wall of the fuel tank is coated with epoxy resin paint. and
the external wall of the tank paints the high-quality silver power coating.
The transformer explosion-proof device uses YSF8-type pressure relief valve.
