Difference for Dry-Type Transformers and Oil-Immersed Transformers

2024-11-10

1. Overview of Dry-Type and Oil-Immersed Transformers

Both dry-type and oil-immersed transformers serve the essential function of voltage transformation, but they differ significantly in design and application. Dry-type transformers use air or solid insulation systems without any insulating oil, while oil-immersed transformers rely on oil for insulation and cooling. Each type has its advantages and is selected based on specific requirements.

2. Technical Cost Comparison

Factor	Dry-Type Transformers	Oil-Immersed Transformers
Overview	Uses air or solid insulation (no oil); ideal for indoor, environmentally sensitive, or fire-risk areas	Uses oil for insulation and cooling; suitable for outdoor and less environmentally restrictive areas
Manufacturing Cost	- High due to expensive materials like silicone rubber and epoxy resin	- Lower due to less costly materials
Manufacturing Cost	- Complex production process with strict quality controls required	- Simpler production process with less stringent environmental controls
Installation Cost	- Relatively low; does not require special containment or handling equipment	- Requires specialized equipment and trained personnel for safe oil handling
Installation Cost	- Installation is straightforward	- Higher installation cost due to oil management
Operating & Maintenance Cost	- Lower maintenance; no need for oil replacement	- Requires regular oil replacement and disposal
Operating & Maintenance Cost	- Minimal waste management required	- Waste oil management incurs additional costs
Environmental Impact	Environmentally friendly; no risk of oil leakage, making it suitable for sensitive installations	Oil leakage risks and disposal requirements lead to additional environmental management costs
Ideal Applications	Indoor installations, high fire-safety requirements, and environmentally sensitive areas	Outdoor installations and applications where environmental sensitivity is lower
