OMEK 1500 kVA Transformer Types and Specifications
1500 kVA Dry Type Transformer
Product Details
This type is designed in cast resin construction and with copper windings. The windings are encapsulated in epoxy resin for protecting against dust and moisture. No insulating oil filled, so there’s no risk of oil leaking.
The 1500 kVA rating provides enough capacity for large three-phase electrical loads. It allows the transformer to be installed close to the load in an indoor electrical room.
Before you decide to select the dry type of 1500 kVA, OMEK recommends consider main factors such as installation space, ventilation, ambient temperature, load profile and noise requirements. If you have any difficulty, don’t hesitate to contact OMEK – your repliable supplier of 1500 kva dry type transformers in China!

1500 kVA Oil Filled Transformer
Product Details
At the 1500 kVA capacity level, heat dissipation becomes an important part of transformer design. OMEK 1500 kVA oil filled transformer uses insulating oil, so the heat generated by the core and windings can be transferred to the transformer tank via the oil, and dissipated to the surrounding environment.
OMEK also uses a spiral winding structure to configure the low voltage winding, and adopts layers design for the high voltage windings. This helps to make a perfect cooling system.
No doubt, this oil filled transformer at 1500 kva is very good at handling large continuous electrical loads.

1500 kVA Pad Mount Transformer
Product Details
Like the 1500 kVA oil filled transformer, the pad mount type is also used for outdoor applications and provides large 3-phase loads.
This ground mounted transformer places the transformer, HV and LV components inside an integrated enclosure. It is compact, weather resistant, easy to install and beautify the environment.
OMEK, as a 1500 kVA pad-mounted transformer manufacturer and supplier in China, can do configurations of radial feed and ring types. Tell us your required connection mode and other requirements, our engineers can measure them and provide you a complete solution.
