Product Description
Ei Type High Frequency Power Transformer 

S11 Series Fully Sealed Power Transformer
1. Brief Description
S11 series oil-immersed transformer adopts traditional compact structure with high reliability. This series of product adopts fully sealed oil tank, thus isolating the transformer oil from the air and slowing down the aging of transformer oil and insulators. This series of product uses traditional material and is efficient and energy-saving.
2. Application Scope
The product has been widely applied in new and reconstruction projects of urban and rural power grids. It is especially suitable for the areas where the electric energy is insufficient, the load fluctuation is big and the daily maintenance is difficult. As the transformer adopts fully sealed structure and avoids contact with the air, it may run in the humid environment and is the ideal power distribution equipment for urban and rural power distribution network.

5. Normal Service Conditions
Height above sea level: Not greater than 1,000m;
Ambient temperature: Maximum temperature: +40ºC;
Maximum daily average temperature: +30ºC;
Maximum annual average temperature: +20ºC;
Minimum outdoor temperature: -25ºC;
Installation environment: ground acceleration caused by earthquake: ag<2m/s
6. Features
1. Simple maintenance.
2. As the low voltage adopts copper foil winding, the electric field distribution of transformer is uniform. The low-voltage inner frame adopts formed hard paper tube, while the high-voltage outer half lap is wound with tasteless glass adhesive tape layer by layer. The compression pad adopts the laminated wood, thus enhancing the mechanical strength of the transformer. The transformer uses vacuum oil filling, which may totally eliminate the bubble in the coil, so as to improve the overall ability of the transformer to withstand the sudden short circuit.
3. The tank rim adopts stainless steel bolts, with beautiful appearance.
4. The oil tank adopts the fully sealed tank, thus isolating the transformer oil from the air, and slowing down the aging of transformer oil. The sealing elements adopt formed parts, with the sealing reliability of the transformer enhanced.
IV. SZ11 Series On-load-tap-changing Power Transformer
1. Brief Description
SZ11 series on-load-tap-changing oil-immersed transformer is an upgraded product developed based on S11 series oil-immersed transformer. The voltage fluctuation and load change of power grid lead to fluctuation of output voltage of transformer during the running. If the voltage is too high or too low, the electric equipment will fail to work normally and even be burnt, and the insulation and efficiency of the transformer will be influenced. To ensure the variation of the output voltage within a reasonable range, voltage regulation is necessary. The product may operate the on-load tap changer manually or automatically to regulate the voltage when it is loaded, or realize remote voltage control through a controller.
2. Application Scope
The product applies to the users who require stable voltage and the voltage fluctuation of power grid is big.
