UL/cUL Listed 25Kva Single Phase Pole Mounted Overhead Distribution
Transformer 7200V to 120V DOE 2016 CSA ANSI IEEE Standards
The 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
reliability in continuous operation, simple maintenance, long
service life, small infrastructure investment, and reduced
low-voltage power supply radius. It can reduce low-voltage line
losses by more than 60%. The products are widely used in industrial
and agricultural power grid transmission and distribution.
