Features
1. The low-voltage coil is wound with foil, and the foil winding is solidified into an integral structure after end sealing. The high-voltage coil is poured with epoxy resin in a vacuum state, and after curing, it forms a solid long cylindrical whole. High mechanical strength, small partial discharge, high reliability, high resistance to short circuit and lightning strike.
2. The resin layer inside and outside the coil is thin, and the heat dissipation performance is good. The cooling method generally adopts air natural cooling (AN). For transformers of any protection level, an air cooling system (AF) can be configured to improve short-time overload capability and ensure safe operation.
3. Low loss, good power saving effect, economical operation and maintenance-free.
4. Small size, light weight, small footprint and low installation cost. Oil drain pools, fire-fighting facilities and backup power sources etc. do not need to be considered.
Ordering Instructions
1. The main parameters of the transformer (voltage, capacity, loss and other main parameters).
2. The operating environment of the transformer (altitude, temperature, humidity, location, etc.).
3. Other customization requirements (coupling group, color, oil pillow, etc.).
4. The MOQ is 1 set.
5. The normal delivery time is 30 days, global fast delivery.
