(OP)
I'm using a 460VAC/230VAC single phase transformer. My customer insists wanting to have 440VAC/220VAC one instead. The ratio between the two transformers are the same. How different are the two? Are they essentially the same ?
Thank you,
Thank you,

What part of the world are you in. Those voltages have been obsolete in North America for quite a while now. North American standard voltages are 120 V, 208 V, 240 V, 277 V, 347 V, 480 V and 600 V.

RE: transformer voltage
But in a nutshell, they have two voltage levels. Service Voltage and Utilization Voltage. This recognizes the fact that you will have some voltage drop in your distribution and branch circuit systems.
You will notice that your house has a nominal 120/240 Volt system, but that most appliances (toasters, microwaves, hair dryers, etc.) are listed for either 110 or 115 Volts.
At industrial levels, you buy a 460 Volt motor for connection to a 480 Volt system.
RE: transformer voltage
460 volts was chosen as a compromise voltage for motors so as to be compatable with the old 440 volt delta iondustrial systems in wide use and the newer 480 volt wye industrial systems.
I changed out some 333KVA / 460 V transformers a few years ago. They had been used for years on 480 volts and were replaced with 480 volt units.

I would guess that you are in the UK and your customer is remembering the older common voltage. What is you applied voltage?
