Scope

Scope: This document specifies the evaluation indicators and methods for assessing the quality and enterprise standard level of medium- and low-voltage cables with a rated voltage of 0.6/1kV to 26/35kV, as well as the classification of their levels. This document applies to the quality and enterprise standard level evaluation of medium- and low-voltage cables with a rated voltage of 0.6/1kV to 26/35kV. Relevant institutions may refer to it when conducting quality grading, enterprise standard level assessments, and "leader" evaluations, and enterprises may also use it as a reference when formulating their own enterprise standards. Main Technical Content: 4.1 Basic Requirements - In the past three years, the enterprise has had no major environmental, safety, or quality accidents. - The enterprise should not be listed on the national credit information list of entities with serious trustworthiness violations. - The enterprise may establish and operate corresponding quality, environmental, and occupational health and safety management systems according to GB/T 19001, GB/T 24001, and GB/T 45001, and is encouraged to establish higher-level related management systems based on its own operations. - The products should be mass-produced, and the medium- and low-voltage cable leader standard of 0.6/1kV to 26/35kV should comply with the requirements of GB/T 12706. 4.2 Evaluation Indicator Classification 4.2.1 Basic Indicators - For cables with a rated voltage of 0.6/1kV to 1.8/3kV, the basic indicators include structural dimensions, cable marking, electrical performance (including conductor DC resistance, finished product voltage withstand test, volume resistivity, and insulation resistance constant), mechanical performance of the sheath before and after aging, low-temperature/high-temperature pressure/thermal shock test of PVC sheath (ST2 type requires additional thermal loss test), carbon black content/thermal shrinkage test of polyethylene sheath (ST7 type requires additi
