Frequently asked questions (FAQ)

Q: What is a dry-type transformer?

A: Dry-type transformers are stationary equipment that utilize an environmentally friendly temperature insulation system, commonly referred to as "cast resin transformers." These transformers are installed within a well-ventilated enclosure, where the coils are effectively cooled by the air circulating inside.

Q: Can dry type transformers be used outside?

A: Dry-type transformers are versatile in their installation, suitable for both indoor and outdoor environments. For indoor applications, they may be housed within a basic IP23 enclosure; however, this level of intrusion protection is often unnecessary due to the inherent security features of these transformers. Consequently, they can be positioned indoors with minimal concern near pedestrian traffic.
For outdoor installations, various design solutions are available to address challenging environmental conditions. Dry-type transformers can be enclosed to safeguard against dust and moisture exposure. Notably, they demonstrate reliable performance even in harsh settings such as open-cast coal mines, where fine and electrically conductive dust poses significant challenges.

Q: What is the difference between oil type and dry-type transformer?

A: Oil-immersed transformer is low cost, easy to maintain, but flammable and explosive; dry-type transformer has good fire resistance, easy to transport, no need for base and oil seepage pool, can be installed in the load centre area, reduce voltage loss and power loss.
