Pole Mounted Single Phase Transformers

Pole Mounted Single Phase Transformers Description

Our pole mounted single phase transformers with UL/cUL, CSA, SGS, and CESI certificates. Pole Mounted Single Phase Transformer is an oil-immersed transformer. Rating ranging from 10 kVA to 333 kVA.Our Transformer takes pride in its ability to provide customizable and in-stock solutions for single-phase transformers, catering to a spectrum of industry requirements. Our pole transformer's commitment to versatility ensures that these transformers can seamlessly adapt to specific needs, including dual-pressure systems and specialized accessories.

Pole Mounted Single Phase Transformers play an important role in many applications. They are widely used in urban power distribution, rural power supply, industrial production and commercial buildings. In urban power distribution, these pole type transformers reduce the voltage of high voltage transmission lines to a level suitable for urban power needs, providing reliable power to domestic, commercial and industrial facilities. In rural power supply, our transformers support agricultural production and residential life, providing stable and reliable power. They are also widely used in industrial production and commercial buildings to ensure the stable operation of factories, manufacturing equipment and other industrial facilities.

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.
