Two kinds of transformers

Farady dry type transformer are usually used indoors, fire safety requirements are relatively high occasions. Oil filled transformers are usually outdoors, of course, can also be used indoors, farady oil immersed transformer failure might fuel injection and combustion, so indoor use more dangerous. Dry Transformers usually not spontaneous, high-quality products with flame retardant capabilities. Dry type transformers advantage is safe, clean, the disadvantage is the high price, accounting for a large area, outdoor use difficult; oil immersed transformers advantage is the voltage level can be very high, accounting for small size, wide range, the disadvantage is oil spills, pollution of the environment when failure. Two kinds of transformers follow different standards, different temperature requirements, the thermal performance of different structure is unfair. Structurally speaking, oil immersed transformer Good heat dissipation device.
