| High Light | 45kVA single phase pad mounted transformer ，13800V to 120/240V transformer with warranty ，304 stainless steel URD transformer | ||
The 45 kVA single-phase pad-mounted transformer converts 13800V primary medium voltage down to 120/240V secondary low voltage, designed specifically for outdoor commercial and underground distribution networks. Configured with a loop-feed primary architecture, dead-front safety construction, and a 4-position loadbreak switch, it enables seamless sectionalizing and maintenance flexibility without interrupting local service.
Built with 100% 304 stainless steel enclosure and base, filled with biodegradable FR3 natural ester fluid, and compliant with DOE 2016 efficiency and ANSI C57.12.38 standards, this unit provides exceptional long-term corrosion resistance and environmental safety. It is engineered for harsh, high-humidity, coastal, or underground-fed infrastructure projects requiring reliable power delivery.
