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

Standard wall

The nominal insulation thickness that complies with this Part, according to different

voltage grades, different conductor cross-sections and properties of low-smoke insulation

materials.

4 Classification, code, specifications and structure of cables

250 V, 750 V, 1.500 V and 3 000 V.
