3.2 Definitions
Type test (symbol T)
Type test refers to the test conducted on the type of wire or cable specified in this standard before it is put into supply according to general commercial principles to prove that the wire or cable has good performance and can meet the specified use requirements. The essence of type test is that after these tests are carried out, there is no need to repeat them. If changing the material or design of the wire or cable will affect the performance of the wire or cable, it must be repeated. 3.2.2
Sampling tests sampletests (symbol S) Sampling tests refer to tests conducted on finished product samples or components taken from finished wires to prove that the product meets the design specifications. 3.2.3
Mutine.Jests [symbol R] Routine tests refer to tests conducted by the manufacturer on all wires or relays. 32.4
Tated voltage
Rated voltage is the standard voltage for the cable to be tested for electrical performance. Rated voltage is expressed in VW, and the unit is V. It is the effective value of the voltage between the open-phase conductor and the "ground". It is the standard effective voltage between any two-phase conductors of a multi-core cable or single-core cable system.
When using an AC system, the rated voltage of the wire or cable shall be at least equal to the standard voltage of the wire or cable system, and the device is applicable to both core and core.
When using a DC system, the nominal voltage of the system shall not be greater than 15 times the rated voltage of the cable. Note: If the working voltage of the system exceeds 10% of the rated voltage of the system for a long time, the rated voltage of the cable shall be at least equal to the standard voltage of the system when the rated voltage is less than 10%. 4 Symbols and codes

Method4 Sheath
6.4.1 Material
For each type of protective sheath, select the latest cross-linked deep-vinyl vinyl material, XLPVC/SX9n - for conductor temperature 90T: the outer sheath of the conductor. 6.4.2 Bridge wrap for outer sheath of XLPVC/SX10 type - 1 temperature-conducting cable
JB/T10438—2004
The cross-linked polyvinyl chloride insulation sheath can be extruded over the variable-strength polyvinyl chloride insulation core, and should not be penetrated by rain. The surface of the cross-linked polyvinyl chloride insulation should be flat, color and chromaticity:
6.4.3 Thickness
The average value of the thickness of the cross-linked polyvinyl chloride insulation sheath should be less than the specified value of the cables of the new models and specifications listed in Table 4, and the thinnest point should not be less than the specified value of 85.1mm:
The flat thickness measurement results should be rounded to 7 decimal places. 6.5 Finished product electric shrinkage test 6.5.1 Mechanical properties of insulation and sheath The visual physical properties of the insulation and sheath of the finished cable shall comply with the requirements of Table 1.
