Product description
Combined American box transformer is to put the transformer body, high-voltage load switch, fuse and other components together in the transformer oil tank. Because it is immersed in oil, the volume of the components is greatly reduced, the structure is more compact, and the installation is convenient and flexible. Fully insulated, fully sealed structure, safe and reliable, easy to operate, maintenance-free. Widely used in residential areas, high-tech centers, factories and mines, airports, stations, schools and other places.
Features
-Compact structure, small size, easy and flexible installation;
-Fully insulated, fully sealed structure, safe and reliable, maintenance-free, reliable protection of personal safety;
-The high-voltage side adopts double fuse protection, in which the plug-in fuse is a dual-sensitive fuse (temperature, current), and the backup fuse is a current-limiting fuse, which reduces the operating cost;
-The high-voltage incoming line adopts a cable connector structure, which is fully insulated, safe and reliable, and easy to operate;
-It can be used for both ring network and terminal, and the conversion is very convenient, which improves the reliability of power supply
-The transformer is a three-phase three-column or three-phase five-column structure, and the iron core adopts a step joint process or a rolled iron core process, which has low noise, low loss, and strong resistance to short circuit and overload.
-Using special processes of vacuum drying and vacuum oiling
-The box can adopt anti-corrosion design and special spray painting according to the requirements of the operating environment. It has “three-proof” functions, namely anti-condensation, anti-salt spray, and anti-mildew functions, and can meet the anti-corrosion requirements in high temperature and high humidity environments.
Scope of application
① Urban public power distribution system, when the load in residential areas and busy streets increases, the transformer capacity needs to be increased.
② Temporary power supply at construction sites: In the case of existing buildings, it is necessary to transform or increase the power supply of electrical equipment, field operations and outdoor work places, such as oil fields, mining, ports, terminals, stations, etc.
