Transformer prices vary substantively, hinging on the specific type and size you require. For instance, a 75 kVA transformer’s price tag can span from $1,336 for a low-efficiency iteration to $3,214 for its high-efficiency counterpart. Smaller transformers, measured at 10MVA or lower, typically start at around $600,000, whereas medium-sized transformers, spanning 10MVA to 50MVA, cost approximately $2,524. It’s crucial to specify the type of transformer you need, as costs can diverge significantly.

What is the Cost of an Opened Transformer versus a Sealed One?
Transformers for electrical isolation and lightning protection come in two main varieties: opened and sealed. The primary factor determining the cost difference between the two is the level of exposure to contaminants and the requirements for maintenance.
Opened Transformers
Opened transformers have accessible compartments for easy maintenance and replacement of components. This design allows for:
- Easier access for repairs and upgrades
- Reduced labor costs for maintenance
The exposed internal components, however, make them more prone to contamination and oxidation, which can lead to premature aging and reduced performance.
Sealed Transformers
Sealed transformers, on the other hand, feature encapsulated internal components, providing a hermetic seal against moisture, dust, and other contaminants. This design offers:
- No risk of internal corrosion or contamination
- Less maintenance required, as there are no movable parts
The sealed design, however, typically comes with increased complexity and production costs, resulting in a higher upfront investment.
Pricing Comparison
The cost difference between opened and sealed transformers primarily lies in the level of manufacturing complexity and the use of specialized materials for the sealed design. Generally:
- Opened transformers: $500-$2,000
- Lower production costs due to simpler design
- Quick and easy maintenance options
- Sealed transformers: $1,500-$5,000
- Higher production costs due to increased complexity
- Longer lifespan due to reduced maintenance requirements
Keep in mind that both types of transformers have their own strengths and weaknesses, and the choice ultimately depends on the specific application and requirements. It’s essential to carefully assess the trade-offs between cost, maintenance, and performance when deciding between opened and sealed transformers.
