Rated voltage is a reference voltage used for cable design
and electrical property test, and identified with Uo/U and
Um in the standard. The meaning of the symbols is defined as
per JB/T 8996.
Uo一Virtual value of the rated voltage between conductor
used for cable design and metallic shield or metallic
sheath, kV;
U一Virtual value of the rated voltage between conductors
used for cable design, kV;
Um一Virtual value of the highest working voltage for
equipment, kV.
In the standard: Uo/U=64/110
Um=126
