Product Description
A single-phase pad-mounted transformer, also known as a single-phase distribution transformer, is a common electrical device used to convert high voltage to low voltage or vice versa. It consists of a core and multiple windings.
The core of the pad-mounted transformer is typically made of silicon steel sheets, which have good magnetic conductivity and low losses. The shape of the core can be square, rectangular, or circular, depending on the application requirements and space limitations.
The windings of the pad-mounted transformer are divided into primary windings and secondary windings. The primary winding is connected to the input power source, while the secondary winding is connected to the output load. By varying the turns ratio between the primary and secondary windings, the pad-mounted transformer can provide the desired voltage transformation.
The transformer is also equipped with protective devices such as overcurrent protectors, over-temperature protectors, and ground fault protectors to ensure the safe operation of the equipment.It meets the following standard:IEC60076, ANSI/IEEEC57.12.00, C57.12.20, C57.12.38, C57.12.90 CSAC27.3 and etc.
