This series of dry-type transformers with fillers and thin insulation. Because the coils are encapsulated by epoxy resin,they are flame-retardant, fireproof, explosion-proof,maintenance-free, pollution-free and small in size, and can be directly installed in the load center.
Meanwhile,the scientific and reasonable design and pouring process make the product have a smaller partial discharge amount, lower noise and stronger heat dissipation capacity.Under the condition of forced air cooling, it can operate continuously at 140% of the rated load for a long time, and is equipped with an intelligent temperature controller for centralized monitoring and control.
The foil-type coil can solve problems such as high short-circuit stress of products wound with low-voltage and large-current coils, unbalanced ampere-turns, poor heat dissipation effect, large winding helix angle, and unstable quality of manual welding.
At the same time, the winding ends of our company adopt resin sealing, curing, moisture-proof and anti-fouling measures, and the copper busbars are automatically welded by argon arc welding.
