The rated voltage is the reference voltage used for cable design and electrical performance testing. The unit is volts. The rated voltage is the effective value of the voltage between any insulated conductor and "ground" (surrounding medium, metal shielding, etc.) or any two insulated conductors. When the cable is used in an AC system, the rated voltage of the cable should be at least equal to the nominal voltage of the system to ground. When used in a DC system, the nominal voltage of the system to ground should not be greater than 1.5 times the rated voltage of the cable. 5.1.2 Long-term operating temperature of the cable

5.2.5 For conductors twisted by single wire bundles, the single wires must be tinned. Tinned single wire bundle stranded conductors are allowed to be tinned as a whole, but the thickness of the tinned layer must be controlled so that the overall tin plating will not bond the single wires together. 5.2.6 The conductors of single conductors and the bundled conductors are not allowed to have joints as a whole. Single wires of bundled conductors can have joints, but the two joints should be at least 0.3m apart. The pitch ratio of the twisted conductors should not be greater than 20. 5.3 Insulation
5.3.1 The polyvinyl chloride material used for insulation should ensure that the performance of the finished ribbon cable meets the requirements of this standard. 5.3.2.

5.3.4. The insulation can be extruded onto parallel-placed conductors at once, or laminated to parallel-placed conductors to form a ribbon cable. When extruding or laminating insulation, tear grooves should be formed on both sides of the conductor, and the depth of each tear groove should not be less than 0.24mm. The thickness of the thinnest point of insulation between the upper and lower tear grooves should not be less than 0.1mm. The distance between the thinnest part of the insulation in the upper and lower tear grooves and the center of the nearest conductor should be no less than 0.5mm. See Appendix A for the test method for tear groove size. GB14316-93 | Insulation can also be extruded onto the conductor to form a single insulated core, and then a film is used to adhere the insulated cores in parallel to form a ribbon cable. The adhesion material should have no adverse effects on the insulated cores. Or a layer of film can be extruded on parallel insulated cores to form a ribbon cable. Before being adhered or extruded into a ribbon cable, a single insulated wire core shall withstand the AC 50Hz spark test specified in GB3048.9. As an intermediate test, the test voltage is 2500V and the duration is not less than 0.2s. 5.3.7 The ratio of the minimum insulation thickness and the maximum insulation thickness of the bonded molded ribbon cable should not be less than 0.65. 5.3.8 No matter what kind of molded ribbon cable it is, the thickness of the thinnest point of the insulation should not be less than 0.18mm. 5.3. For ribbon cables with less than 93 cores, the insulation thickness and tear groove size of the cores should all be inspected. For ribbon cables with more than 3 cores, at least 3 cores and 3 groups (upper and lower are one group) of tear grooves should be selected for inspection. All inspections should be made during the arbitration test. ) The color of the insulated core of the colored ribbon cable should comply with the regulations of GB6995, and should be selected according to the regulations in Table 4. 5.3.10
