3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB/T 2900.10 and the following apply.
3.1
rated voltage
reference voltage for cable design, service and electrical property test
Note: rated voltage is expressed by U0/U.
U0 represents the voltage r.m.s. between any main insulated conductor and the "ground" (metallic shield, metallic sheath or surrounding medium); U represents the voltage r.m.s. between any two-phase conductors of multicore cable or single-core cable system.
For AC system, the rated voltage of the cable is at least equal to the nominal voltage of the system using the cable, and this condition applies to both U0 and U values; for DC system, the nominal voltage is not greater than 1.5 times the rated voltage of the cable.
The working voltage of the system is not greater than 1.1 times the nominal voltage of the system.
3.2
nominal value
value by which a quantity is designated and which is often used in tables
Note: in this standard, the quantity value evolved from nominal value is generally inspected through measurement with consideration of the specified tolerance.
