25KVA Single Phase Pole Distribution Transformer 12470V To 277V
ANSI IEEE
Product Overview
The single phase pole mounted transformer is a fully sealed
cylindrical structure and is installed by pole-mounted suspension.
It has the advantages of small size, strong overload capacity, high
continuous operation reliability, and simple maintenance.
The pole-mounted transformers produced by WINLEY ELECTRIC have
rated capacities ranging from 10 kVA to 333 kVA, meeting ANSI/IEEE
C57, IEC60076 and other standards, and meeting or even exceeding
DOE and CSA efficiency requirements. Our products have been
exported in large quantities to markets such as North America,
Central and South America, and Southeast Asia, and have been widely
praised.
