Product Description

   
  Kexun is a power transmission and transformation equipment factory in China. Its beauty American Box Type Substation is well known for its good protective performance, high standardization, simple maintenance and wide applicability.

 Product advantages
1. The Pre-installed American Box Type Cabinet have compact and standard structure, small floor space, far less than the European type with the same capacity.
2. Sealed, insulated structure, strong safety.
3. The Pre-installed American Box Type Cabinet adopt transformers with low loss, low noise, low temperature rise, strong overload capacity, short circuit resistance and strong impact resistance ensures the high performance of the product.
4. Accept various solutions to meet the customized needs of customers and deal with different usage scenarios.
 Transformer
Pre-installed American Box Type Cabinet adopt S11 series three-phase oil-immersed transformer with low loss, low temperature rise and low noise is adopted. Fully sealed structure effectively isolates the air pollution and insulation degradation caused by moisture. The corrugated sheet of the oil tank shell has the functions of heat dissipation and cooling, and effectively reduces the internal pressure.
 Two-station terminal load switch
Its structural diagram is shown in Figure 4, in which "I" is connected to the high-voltage incoming terminal. During operation, the user inserts the special operating handle into the rotating shaft of the load switch and rotates it 90 degrees counterclockwise, and the load switch turns to the "off" position. The terminal load switch only cuts off the transformer branch in the terminal power supply mode or works when replacing the plug-in fuse core, so the terminal negative load switch only has two positions of off and on, and the operating force is also small due to its small size. In order to reduce the oil pollution in the oil tank, it is suggested that the user turn off the low-voltage switch before operating the load switch to reduce the pressure side load.


 

 Environmental Conditions of Use
 Environment temperature : The Pre-installed American Box Transformer should be use in the environment between -30~40ºC
 Altitude : Below 4000m
 Wind speed : Below 34m/s
 Humidity : The average daily relative humidity is not more than 95%; The monthly relative humidity value is not more than 95%
 Shockproof level :The horizontal acceleration is not more than 0.4m/S², and the vertical acceleration is not more than 0.15m/S²
 Installation inclination : Within 3°
 Installation environment :The surrounding air is not obviously polluted by corrosive and combustible gases, and there is no violent vibration at the installation site.
Note :When ordering Pre-installed American Box Transformer beyond the above conditions, you can negotiate with our company.
 Insert Type Fuse
Its melting core has dual sensitivity (temperature and current), that is, it melts when the load side fails (overload or excessive temperature). Plug-IN fuse and backup protection fuse are used in series, which can protect the whole range from small current (several times in) to large current (several tens of kiloamperes), and the maximum breaking current is 50kA.
