75 Kva Power Pole Transformer Single Phase Pole Mounted Overhead Distribution 34.5kv To 120v Ansi Ieee Doe 2016 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.

Drawing
The transformer is cylinder sealing structure. Each one is fixed with grounding devices, hooks, sup porting lugs which conforms to ANSI standard, and one or two high voltage bushing on the cover, low voltage bushing on the wall of the tank and eyebolt,connecting terminals. The tap changer should be adjusted basing on the instruction after the power off.
Core features
* Available option of FR3 fluid for increased fire safety or electrical grade mineral oil
* Meets or exceeds industry standards including ANSI, NEMA and DOE Energy Efficiency
* Constructed with EPRI-recommended interlaced core-type design for greater resistance to low-side voltage surges
* Polymer low-voltage bushings are standard at 5-50 kVA
* Cores and coils designed for high reliability and low field failure rates: Available in grain-oriented electrical or amorphous steel
* Domed cover design and formed cover band provide increased pressure withstand capability, eliminate bushing overhang and improve cover retention
* High-voltage bushing design improves gasket protection and seal
*Configurable to Rural Utilities Service (RUS) specification
