Package and transport
The transformer accessories are packed in plywood boxes, the box is made of high strength iron frame and covered with non-fumigation ply wood plate, the transformer main body is nude and fixed in the container, some of the big transformers will equipped with impact recorder to record the G value during sea transportation.
How Does a Transformer Work?
A transformer is basically a large, square magnet with a hole in the middle. Electricity enters on one side via wires wrapped a number of times around the transformer, and leaves on the opposite side via wires wrapped a different number of times around the transformer. Entering electricity induces a magnetic field in the transformer, which in turn induces an electric field in the other wires, which then carry power away from the transformer.
At the level of physics, a transformer works by taking advantage of Faraday's law, which states that the voltage ratio of two coils equals the ratio of the number of turns in the respective coils. Thus if reduced voltage is required at a transformer, the second (outgoing) coil contains fewer turns than the primary (incoming) coil.
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)
