SCB -10 Step Down Cast Resin Dry Type Transformer / Electrical Transformers
Product Structure:
1. Iron core:
it is made of high-quality grain orientation cold rolled silicon steel sheet, and adopts 45° full-inclined joint structure and five-grade stepping.
2. Pouring coil:
it adopts F grade insulated copper conductor as the conductor, and adopts glass fiber and epoxy resin composite material for insulation.
3. Foil type coil:
it is automatically winded by foil type coil winding machine and adopts argon shield technology to perform internal welding.
Cast-foil Coil: Adopting the entire section of copper foil, together with the F-class turn insulation, low voltage winding is wound by the special low-voltage foil winding machine. The foil coil resolves such understanding problems as large short-circuit stress, uneven ampere turn, poor heat dissipation, existing the winding spiral angle as well as unsteady manual welding quality due to low voltage and large current coil winding products. At the same time, the winding end in our company is treated with resin potting, solidification to make shape, moisture-proof and anti-fouling, the lead copper platoon is automatically welded by argon arc welding.
4. Temperature Control Device: the transformer adopts temperature cntroller and PT 100 temperaure measuring component ,which are embedded in the hottest point of the coils for realizing the temperature measuring and controlling of transformer.It can automatically detect and dynamically display the work humidity of phase coils and also have the functions of over-temperature alarm and trip.
