Energy Loss Reduction
One of the key advantages of LE transformers is their ability to save energy thanks to the low no-load loss of only 433W. This helps businesses significantly reduce operating costs throughout the product lifecycle.
Open-Type Design For Easy Maintenance
Compared to sealed oil transformers, the 400 kVA Open-Type Three-Phase Transformer features a more accessible structure that simplifies inspection and periodic maintenance. This design is particularly suitable for facilities with spacious installation areas, professional technical systems, and regular operational monitoring requirements.
The 400 kVA transformer is designed in an open-type structure for easy maintenance.
High Durability And Adaptability
LE transformers are manufactured using high-quality materials, low-loss electrical steel cores, and pure copper windings, ensuring excellent durability and strong load-bearing capability. The product performs effectively in various environmental and geographical conditions, from industrial parks to infrastructure projects and production facilities.
COMPARISON WITH OTHER TRANSFORMER TYPES
- Compared to smaller-capacity transformers such as 100 kVA, 160 kVA, or 250 kVA models, the 400 kVA transformer can handle significantly larger electrical loads, making it an ideal choice for medium- and large-scale industrial systems. It is especially suitable for businesses expanding their operations or operating multiple high-power machines simultaneously.
- Compared to sealed-type transformers, open-type transformers offer superior heat dissipation, easier maintenance, and more convenient technical inspection. However, they are generally more suitable for environments with controlled installation conditions and lower exposure to dust or excessive humidity.
- Additionally, when compared with many products currently available on the market, LE transformers stand out for their optimized energy efficiency, reliable performance, and strictly controlled manufacturing processes.
