75Kva Single Phase Pole Mounted Transformer Overhead Distribution
Dual Windings 34500V to 120/240V UL/cUL Listed
The Overhead Distribution Transformer is a conventional,
single-phase, liquid-filled, pole-mounted unit designed for
efficient power distribution. With a capacity of 75 KVA, it
operates at primary and secondary voltages of 34500V and 120/240V,
respectively. The transformer meets DOE 2016 efficiency standards
and complies with ANSI/IEEE standards, achieving 99% efficiency.
The pole-mounted transformers produced by WINLEY have obtained
UL/cUL certification, with rated capacities ranging from 10 kVA to
250 kVA. The products meet or even exceed ANSI/ IEEE, CSA, IEC60076
and other standards.

Performance Characteristic
1. The products are widely used in power transmission and
distribution of industrial and agricultural power networks.
2. Iron core is made of cold-rolled silicon-steel sheet with high
conduction of magnetism and adopts pulling-plank structure, so that
its magnetic route is short, losses and noise level is low.
3. Compress wire is adopted for winding so losses are low and have
good ability withstand short-circuit.
4. The oil tank is bell type with the structure of full folding
plate type, having an excellent exterior and easy for maintenance.
