Check before running
1. Check whether all fasteners and connectors are loose and tighten them again.
2. Check whether the parts removed during transportation are properly reinstalled, and check whether there are foreign bodies in the transformer, especially in the high and low voltage air duct of the transformer and on the underlying pad.
3. Check whether the fan, temperature controller, temperature indicator, on-load switch and other accessories can work normally. For the three-phase power fan, attention should be paid to its steering. When the fan is normally turning, the wind blows upward from the bottom of the coil into the line
Circle, otherwise, it will be reversed, please replace the phase sequence of the fan power.
Transformer packing
How to solve the abnormal temperature rise?
1.Modify or replace the instrument
2.Reduce the load, balance the load of each phase, increase the transformer capacity
3. Change the wiring
4.Clean the dust
FAQ
1. Where is your main market?
We had exported our transformers to more than 30 countries in the world, our main market is Africa countries, South and North American countries, and Asia countries.
2. What certificate do you have?
We have KEMA, CESI, CTQC type test report for our transformers.
3. How long is your delivery time?
30 days after drawing confirmed by buyer for distribution transformers below 5000kva, bigger transformers depend on the capacity and components, normally 30-90days(with imported components)
