12470Y/7200 120/240V pole mounted transformer is mostly used in the North American market. The transformer is small in size and easy to install. It is very suitable for the terrain of the United States.
Basic information:
For single-phase double-winding transformers, the material of the windings can be either copper or aluminum.
12470Y/7200 120/240V pole mounted transformer capacity range is generally 5 to 167kva and is mainly customized according to the customer’s requirements.
The high-voltage side voltage is 12470Y/7200V. “Y” indicates the connection method, representing star connection. The low voltage is generally 120/240V, which is quite suitable for powering residential areas or small commercial districts.
60Hz is mostly used in the power supply of the United States.
Technical characteristics:
Insulation level
The insulation level is generally required to be relatively high, and it needs to be able to withstand an overvoltage impact of 95kv. This can ensure the insulation requirements that the transformer should have and guarantee its safe and stable operation.
Cooling method
The ONAN cooling method is adopted, and the mineral oil filled in the transformer is used as the medium to achieve the purpose of cold zone and insulation. At the same time, it can also dissipate heat to prevent the transformer’s temperature from being too high, so as to avoid transformer malfunctions.
Energy efficiency standard
According to the customer’s requirements, it is necessary to comply with local energy efficiency standards. When energy efficiency is higher, the loss will be lower and the operating cost will also decrease accordingly.
Safety and Protection:
12470Y/7200 120/240V pole mounted transformer needs to be equipped with a pressure relief valve. The purpose is to control the pressure stability inside the transformer. When the pressure is too high, the pressure relief valve will automatically open to release the excess pressure. It is also equipped with an oil drain valve, which facilitates the regular replacement of transformer oil. A grounding device is required to ensure the grounding safety of the transformer during operation.
Application scenarios:
The overhead design can be applied to various scenarios. It is very suitable for densely populated areas to provide efficient and stable power supply. This transformer can also be used if there is a small power demand.
