50 KVA Overhead Distribution Transformer Pole Mounted 24940V to 120V DOE 2016 Efficiency UL/cUL certified
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.
The rated capacity of pole-mounted transformers produced by WINLEY Electric ranges from 10 kVA to 333 kVA. The products meet IEEE/ANSI/DOE/CSA and IEC standards, and have obtained UL/cUL certification. The products have been exported in large quantities to North America, Central and South America and other markets.
