2 Terms and definitions
The following terms and definitions apply to GB/T 5013 parts.
GB/T 5013.1-2008/IEC 60245-1..2003
2.1 Insulation and sheathing material definition
2.1.1
The mixture is classified according to the measured properties of the prescribed test.
Note. The model number is not directly related to the composition of the mixture.
2.1.2
Eraser blends are properly selected, formulated, processed and vulcanized, and its unique components are rubber and/or synthetic elastomer blends.
Note. Vulcanization refers to the next process of insulation and/or sheath extrusion, in order to permanently crosslink the elastomer.
2.1.3
Elastomers of vulcanized mixtures are neoprene or other comparable synthetic elastomers that behave like PCP.
2.1.4
The elastomers of the crosslinking mixture are ethylene-vinyl acetate or other comparable synthetic elastomers similar in performance to EVA.
2.1.5
The elastomer of the crosslinking mixture is ethylene-propylene rubber or other comparable synthetic elastomer with properties similar to those of EPR.
2.1.6
The appropriate choice, proportioning and processing of the PVC material mixture with the appropriate cross-linking agent, after cross-linking to achieve the subsequent detailed specification
Performance requirements.
2.2 Test definition
2.2.1
Type test refers to the general commercial principle, GB/T 5013 provisions of a type of cable before the test carried out to prove that electricity
Cable has good performance, to meet the requirements of the use of the provisions.
NOTE The essence of type testing is that it is not necessary to repeat the tests once these tests have been carried out unless the cable material or design changes affect cable performance.
2.2.2
Tests on finished cable samples or on components taken from finished cable to demonstrate that the finished cable product conforms to the design specifications.
2.3
The rated voltage of a cable is the reference voltage for cable design and electrical performance tests.
Note 1. The rated voltage U0/U that the unit is V.
U0 is the voltage rms between any insulated conductor and "ground" (metal sheath of the cable or surrounding medium).
U is the voltage rms between any two phase conductor in a multi-core cable or single-core cable system.
In AC systems, the rated voltage of the cable should be at least equal to the nominal voltage of the system in which the cable is used. This condition applies to U0 and U values.
In DC systems, the system nominal voltage should not exceed 1.5 times the rated voltage of the cable.
Note 2. The operating voltage of the system allows to exceed 10% of the nominal voltage of the system for a long time. If the rated voltage of the cable is at least equal to the nominal voltage of the system,
The cable can be used at a working voltage higher than 10% of the rated voltage.

Light blue or brown; on the other layers, one core is brown and the other cores are the same color, but not green, yellow, light blue or brown, or
On the outer layer, one core is light blue, one core is brown, and the other core is the same color, but not green, yellow, light blue or brown; in its
He layer, a core is brown, while the other core is the same color, but not green, yellow, light blue or brown.
Various colors should be able to clearly identify and scratch. Should according to GB/T 5013.2-2008 test method specified in 1.8 test.
4.1.3 green/yellow combination color

70% while the other color covers the rest of the insulated core.
Note. For the case of using green/yellow combination colors and light blue colors Note. When green/yellow combination colors are specified as above, it is used exclusively for identification of connection ground or similar
Insulation core for protection purposes. Light blue is used to identify the insulated core to which the neutral is connected. If there is no neutral, light blue can be used to identify the ground
Or any insulated core other than the protective conductor.
