COMPARISON WITH OTHER TRANSFORMER TYPES

Compared to Oil-Immersed Transformers

• Oil transformers are suitable for outdoor installation with effective cooling performance.
• However, the 250 kVA open-type transformer offers clear advantages for indoor use: No risk of oil leakage, easier maintenance, lower operating costs in many cases.

Compared to Dry-Type Transformers

• Dry-type transformers provide high safety and excellent fire resistance.
• However, they typically come with higher initial investment costs.
• LE’s open-type transformer delivers an optimal balance between performance - cost - durability.

Compared to Lower Capacities (100-160 kVA)

• Easily overloaded as production expands
• Insufficient for high-power equipment
• In contrast, the 250 kVA model provides better capacity margin and supports long-term growth

APPLICATIONS OF THE 250 KVA THREE-PHASE OPEN-TYPE TRANSFORMER

This product is widely used in:

• Medium to large-scale manufacturing plants
• Industrial zone enterprises
• Internal factory power distribution systems
• Mechanical workshops, processing plants, and continuous production facilities

It is especially well-suited for industrial zones with medium to high load demands, where stable power supply and cost efficiency are essential.
