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.
