Foreword
TB/T 1484 Cables on board rolling stock is divided into the following parts.
- Part 1. Standard wall insulation cables up to AC 3 kV;
- Part 2. Thin wall insulation cables;

3 Terms and definitions
For the purpose of this document, the terms and definition determined in GB/T
2900.10-2001 AND the following terms and definitions shall apply.
3.1
Rated voltage
The reference voltage in cable structure design and electrical performance test,
expressed in U0, the unit is volts (V).
Note 1. U0 is the voltage effective value between one insulated conductor and ground (the metal sheath
of cables or surrounding medium of cables). In AC systems, the rated voltage of one cable shall at least
be equal to the system nominal voltage of this cable used. In DC systems, the nominal voltage of this
system shall not be larger than 1.5 times of the rated voltage of this cable.
Note 2. The working voltage of this system is allowed to exceed 10% of the nominal voltage of this
system for a long time. If the rated voltage of one cable is at least equal to the nominal voltage of this
system, the cable can work under the working voltage being higher than 10% of the rated voltage.
3.2
Thin wall insulation
The wall insulation that, according to different voltage grade and different conductor cross
section, adopts special high performance insulation properties, which meet the insulation
thickness of reduction in this Part.
