Frequently Asked Questions
What are the primary benefits of using a cast resin dry type distribution transformer?
Cast resin dry type transformers are exceptionally safe, flame-retardant, explosion-proof, and completely eco-friendly. Since they don't use oil insulation, they pose no risk of leakage, making them perfectly suited to be installed directly in high-density load centers.
Can these transformers operate effectively under high humidity environments?
Yes. They offer superior moisture-proof performance and are fully capable of maintaining normal operation under 100% relative humidity. The dense resin structure ensures zero moisture accumulation on the coil surfaces.
What cooling methods are supported by your dry type transformers?
They can run on Natural Air cooling (AN) or switch to Forced Air cooling (AF) conditions. Under forced air cooling, the dissipation capability increases substantially to safely accommodate temporary heavy overload conditions.
Where are these dry type distribution transformers most commonly deployed?
They are ideal for heavy-load infrastructure including power distribution grids, commercial buildings, multi-star hotels, stadiums, industrial chemical facilities, metropolitan stations, airports, and offshore drilling platforms.
Are cast resin transformers maintenance-free?
Yes, they are virtually maintenance-free. Because there are no fluids to test, filter, or replace, their structural design allows for an exceptionally simple installation process and minimal operational lifecycle overheads.
How is the mechanical strength and overload reliability achieved?
The high-voltage and low-voltage windings are encapsulated under vacuum conditions using epoxy cast resin. This creates an inherently rigid, compact structure featuring low partial discharge values and exceptional resilience against short-circuit forces.
