Frequently Asked Questions (FAQ)

 

Q: What is protection for the pole mounted transformer?

A: Lightning arresters: These are devices that protect the transformer from lightning strikes. They discharge the high voltage current caused by lightning strikes to the ground, ensuring that the transformer and surrounding electrical equipment are not damaged.

Q: What are the pole mounted transformer's requirements of installation?

A: The height of the cross arm of the drop-out fuse from the ground should not be less than 4.5m. The installation inclination angle of the transformer high-voltage drop-out fuse is 25°~30°, and the distance between phases should not be less than 0.7m. The transformer on the pole should be installed smoothly and firmly.

Q: How are pole transformers wired?

A: The transformer is always connected to the primary distribution lines through protective fuses and disconnect switches. For pole-mounted transformers this is usually a 'fused cutout'. An electrical fault melts the fuse and the device drops open to give a visual indication of trouble.

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.
