Product Overview
Engineered for outdoor distribution networks, this oil immersed transformer features a hermetically sealed tank for leak-proof operation and long service life. It delivers high efficiency with reduced energy loss, helping lower operating costs. Widely used in rural electrification, overhead line systems, residential distribution, and small commercial power networks, it ensures stable performance in outdoor environments.
With high efficiency (up to 98%) and reduced no-load loss (15%–20%), it helps improve energy savings. The sealed tank design prevents leakage and supports maintenance-free operation in harsh conditions from -25°C to +40°C, including humid, coastal, and dusty areas.
Its compact pole-mounted structure allows quick installation and reduced construction cost. Compliant with UL certification, Designed for 60Hz power distribution systems in North American utility applications.
