Frequently asked questions (FAQ)

Q: What is the difference between cast coil and dry type transformer?

A: Cast coils and dry type transformers are two different types of electrical equipment. Cast coils use epoxy seals and in-built cooling systems for high humidity or corrosive environments, while dry-type transformers use dry insulation and are cooled either naturally or by forced air for low-maintenance and environmentally friendly applications.

Q: What is dry type power transformer?

A: Unlike liquid-filled transformers, dry-type transformers do not use liquid to dissipate excess heat and meet temperature classification requirements. Instead, the coils inside a dry-type transformer consist of a gaseous or dry insulating medium.

Q: When to use a dry transformer?

A: Dry-type transformers are ideal for small and medium-voltage uses that can accommodate both indoor and outdoor facilities. By using natural air as a cooling medium, they are less hazardous and have a lower risk of fire disruption. Air-cooled systems also need less maintenance and offer simple installation.

Q: What are the disadvantages of a dry type transformer?

A: Dry-type transformers are expensive to purchase and operate.
Repair is difficult and end-of-life recycling is limited.
If coils are not properly cleaned, they can be a fire hazard.
Annual maintenance usually requires decommissioning and shutdo.
