Distribution Pole Mounted Transformer Description

 

Distribution Pole Mounted Transformer manufactured by TRANSPOWER.Our commitment to excellence extends to every product we offer. We ensure that each transformer meets stringent standards and undergoes thorough acceptance testing, maintaining a 0% failure rate record for over 10 years. Designed to meet international standards such as IEC and ANSI, Pole Mounted Transformer is a model of efficiency and durability.

TRANSPOWER ELECTRICAL's Distribution Pole Mounted Transformer utilizes high quality workmanship materials and advanced manufacturing processes. The core is made of high quality silicon steel sheet to ensure good permeability and low loss. The windings are precision wound. The liquid-filled oil tank is made of insulating oil with excellent insulation properties, which both cools the transformer effectively and provides good insulation protection.

The Distribution Pole Mounted Transformer has a number of structural features that ensure its excellent performance in various application scenarios. First of all, pole type transformer adopts pole mounting method, which is suitable for outdoor environment, saving space and easy to install. Secondly, Distribution Pole Mounted Transformer is well-designed with good heat dissipation and insulation to ensure stable operation for a long time. In addition, our transformers are manufactured with moding technology, which makes them have low noise level and will not cause disturbance to the surrounding environment and people. We also offer a wide range of customized options in terms of rated capacity, voltage level and connection method to meet the diverse needs of our customers.

Frequently Asked Questions (FAQ)

 

Q: What is the minimum clearance for a pole mounted transformer?

A: From Buildings: Transformers on poles shall be so located that normally Unenergized parts clear the surfaces of buildings by not less than 3 feet horizontally or by not less than 8 feet vertically.

Q: How is a pole transformer grounded?

A: The primary bushing on the transformer is connected to the secondary bushing, which is then connected to the secondary neutral. The secondary neutral in turn is directly connected to the ground rods at regular pole intervals.

Q: What is inside a pole mounted transformer?

A: When you open the oil tank cap of a pole transformer, you will see: Insulating Oil: The liquid used for electrical insulation and cooling. Iron Core: The core that forms the magnetic circuit. Windings: The primary (high-voltage) and secondary (low-voltage) coils.

Q: What voltage do pole mounted transformers step down to?

A: The primary voltage varies depending on the distribution system they are connected to. Common primary voltages include 7.2 kV, 14.4 kV, and 34.5 kV. These high voltage levels are stepped down to standard secondary voltages, such as 120/240V for residential use or higher voltages for industrial applications.

Q: Do pole mounted transformers have fuses?

A: Pole-mounted transformers often include accessories such as surge arresters or protective fuse links. A self-protected transformer includes an internal fuse and surge arrester; other transformers have these components mounted separately outside the tank.
