Descripton：
Single-phase pad-mounted transformers are the preferred choice among base-mounted transformers, offering a balance of environmental friendliness, economic efficiency, high efficiency, and safety. These transformers utilize FR3 high-flash-point insulating fluid, providing excellent fire protection performance. Compared with traditional mineral oil transformers, their expected service life is significantly extended. The rated power of these transformers ranges from 10 to 167 kVA, and they are available in various designs such as ANSI Type 1, ANSI Type 2, and Ranch Runner, making them suitable for different application scenarios.
The FR3 fluid is not only biodegradable and non-toxic, but also capable of delivering sustainable performance at an affordable cost. This fluid strictly complies with the ASTM D6871-03 standard and meets the requirements of the IEEE PC57.147 standard which is under application.
The product performance fully meets or even exceeds multiple industry standards, covering ANSI (excluding the Ranch Runner front panel), NEMA, and DOE energy efficiency standards.
The core and coils are meticulously designed to achieve high reliability and significantly reduce the on-site failure rate. It offers two material options: grain-oriented steel and amorphous steel.
The overcurrent protection is well-configured, with Bay-O-Net fuses as standard, and optional current-limiting fuses or weak link components can be selected according to needs.
Both high-voltage and low-voltage bushing terminals are tinned, which can accommodate aluminum or copper conductors to ensure stable and efficient electrical connections.
