440 volt + or - 6% or 440 metres , 3 phases and 50 Hertz

 

[Catalin Neagu]

440 m= lenght of cable(maybe)

6%=max. volt drop admiss(maybe)

volt 3 phase= 400V beetwen phases

50 hertz=The hertz (symbol Hz) is the SI unit of frequency defined as the number of cycles per second of a periodic phenomenon(other country is 60Hz e.g USA,JAPAN etc)

What are you reading that text from?

Sounds like a description you would see on ebay from somebody in Hong Kong selling something to the UK.
