The 75kVA pad-mounted transformer is tailored for utility customers in Canada, featuring a primary voltage of 25kV and a secondary voltage of 480/277V. It strictly adheres to local standards, including CSA C227.4 and CSA C802.1, ensuring optimal efficiency values. Notably, both the high and low-voltage windings are crafted from aluminum or copper.
15kVA Single Phase Pad Mounted transformer
The 15 kVA single phase pad mounted transformer operates safely, reliably, and efficiently and can be installed indoors and outdoors. This type of transformer has a low operating cost, is environmentally friendly, easy to install, and has a low purchase cost, so it is widely used in residential, commercial, and other public.
25kVA Single Phase Pad Mounted transformer
The 25kVA Single Phase Pad Mounted transformer with a power rating of 25 kVA, the high voltage of the transformer is 24940GRDY/14400×12470GRDY/7200V, which is a dual high voltage design. Customers can switch between 14.4kV and 7.2kV through a dual voltage switch according to the distribution line. There is a five-position voltage regulating switch on the high-voltage side, which can allow small changes in voltage within ±2 * 2 ½%. The 25 kVA transformer has bay o net fuse and ELSP fuse to form a double fuse system to protect the transformer from damage in circuit faults. The transformer comes complete with an oil level indicator and a 4-position load break switch, adding to its versatility and ease of maintenance.
37.5kVA Single Phase Pad Mounted transformer
The 37.5kVA Single Phase Pad Mounted transformer with high voltage (HV) specifications of 24.94GRDY/14.4 kV and low voltage (LV) of 240/120V. At its core lies a robust tank, constructed from resilient alloy 304 stainless steel, guaranteeing longevity even in the harshest conditions. The HV and LV windings, equally critical components, are meticulously crafted from high-quality aluminum to ensure unwavering performance.

FAQ From Customers
-
What is a Transformer?A transformer is an electrical device used to change the voltage of alternating current (AC). It works on the principle of electromagnetic induction, converting high-voltage current into low-voltage current or low-voltage current into high-voltage current. Transformers are widely used in power transmission, distribution systems, and various electronic devices.
-
What are the main uses of a transformer?The main use of a transformer is voltage conversion. Transformers are used in power transmission systems to help transfer electricity from power plants to consumers. In addition, transformers are also used in electronic devices such as chargers, televisions, power adapters, etc., to adjust the voltage to meet the requirements of different devices.
-
Do you have UL listed?Yes, our transformer has UL listed. We have exported to America many pad mounted transformer,substation transformer and HV.
