FAQ From Customers
-
What are pole-mounted transformers?
A pole mounted transformer is a type of distribution transformer installed on utility poles to supply electricity to residential, commercial, and rural areas. These transformers are compact, cost-effective, and easy to maintain. Available in both single phase pole mounted transformer and three phase pole mounted transformer designs, they step down high-voltage electricity from overhead power lines to a lower voltage suitable for end users. -
How many kVA is a pole-mounted transformer?
The capacity of a pole mounted transformer typically ranges from 10 kVA to 500 kVA, depending on the power demand and application. Single phase pole mounted transformers are usually between 10 and 100 kVA, ideal for residential or light commercial loads. Three phase pole mounted transformers can reach up to 500 kVA or more for industrial or rural network use. NPC Electric offers custom kVA ratings to match specific voltage and load requirements. -
What is the difference between pole-mounted and pad-mounted transformers?
The main difference between a pole mounted transformer and a pad mounted transformer lies in their installation and application. Pole mounted transformers are installed on utility poles for overhead distribution lines, while pad mounted transformers are ground-mounted and enclosed in secure cabinets for underground systems. The pole-mounted type is ideal for rural or open areas, whereas pad-mounted units are better for urban or industrial environments requiring enhanced protection and aesthetics. -
Do pole-mounted transformers step down voltage?
Yes. Pole mounted transformers are designed as step-down transformers, reducing high transmission voltages (typically 11kV or 33kV) to lower distribution voltages such as 415V or 240V. This allows safe and efficient electricity delivery to homes, offices, and factories. Both single phase and three phase pole mounted transformers perform voltage conversion with high efficiency and reliability, minimizing energy loss in the distribution network. -
How to size a pole mounted transformer?
To properly size a pole mounted transformer, consider factors such as total load demand (in kVA), voltage level, power factor, and future capacity growth. Residential areas may use single phase pole mounted transformers, while commercial or industrial networks require three phase units with higher kVA ratings. NPC Electric provides professional transformer sizing guidance based on load analysis, ensuring optimal performance, energy efficiency, and long service life.
