1. According to our solution, no need use transformer to transform the voltage from 4160V, 60HZ and 3800V, 50HZ to 480V. We advise use the 4160V,60HZ and 3800V,50HZ as the load bank input voltage. That can reduce the cost for the transformer and reduce the load bank dimension. If you don't agree with this solution, what about we offer the load bank input voltage with the voltage 480V, you purchase the transformer by yourself? You know because we don't produce transformer, I think our price will be not good.

Answer 1: No, the load bank must be able to receive a 4160VAC/3800VAC input. That is what our military spec generators are producing.

2. We advise adopt the intergrated design to reduce the dimension and cost of the container.

Answer 2: If you mean, the system should be one complete system (all components consolidated within the trailer mounted unit)….then yes, that is what we are looking for.

3. Considering the load bank will be used at outdoor, we advise adopt the container structure type, not the cabinet type. Because the container type can offer better protection level(IP55):

Control part protection level: IP55; When air intake and air outlet is close, the entirety protection level is IP55; When air intake and air outlet is open, the load part protection level is IP21, other part is IP55.

Answer 3: I don’t understand what IP55/IP21 is at all. If what you are saying is because it’s an outdoor piece of equipment it should be containerized due to the fact it will hold up better against the elements outside…then yes…that is fine by us.

4. The dimension is About 6058mm*2438mm*2591mm（L×W×H）, the weight is about 10000kgs.

Answer 4: The dimensions and weight are satisfactory.

5. About the control power, we use a transformer to transform the internal (4160V,60HZ and 3800V,50HZ) and external(480V) voltage to 380V, our working control voltage and fan voltage can work normally at 380V.

Answer 5: That is just fine. We are only concerned about the input voltage being 4160VAC/3800VAC compatible. The internal control/fan circuitry voltage requirements are not a concern to us.
