Transformer Features
This 25 kVA pad-mounted transformer features a 13,800 V delta
primary (15 kV class, 95 kV BIL) and a 240/120 V dual-winding
single-phase secondary (L–N–L, 30 kV BIL). It is equipped with (3)
2-Position Load Break Switches to enhance operational safety and
flexibility during load management.
This 25 kVA pad-mounted transformer features robust and
corrosion-resistant enclosure components, with its tank constructed
from 316 stainless steel, and both the cabinet and base platform
made of 316 stainless steel. These high-quality stainless steel
materials ensure the transformer's (outer casing) exhibits
excellent durability and weather resistance, making it well-suited
for outdoor installation and long-term operation in various
environmental conditions
