(Reporter/Zhu Weiliang) Guangzhou Municipal Bureau of Industry and Commerce recently announced last year in Guangzhou wire and cable commodity quality inspection results. A total of 100 samples produced by 48 enterprises were extracted, and 18 samples of physical quality were unqualified, which was judged as the overall unqualified supervision, and the unqualified rate was 18.00%. Among them, brand products Guangzhou Guangfo Pearl River wire and cable 2 batches, Guangdong Pearl River wire and cable 3 batches of sample inspection failed.

      The Municipal Bureau of Industry and Commerce has punished the sellers of unqualified goods according to the relevant provisions of the "Product Quality Law", and urged the city's sellers to do a good job of the same producer of the same specifications (paragraph) unqualified goods delisting work, and the sellers who refuse to perform delisting will be investigated and punished in accordance with the law.

      The 18 unqualified samples are all related to conductor resistance (20℃) detection failure, becoming the "major disaster area" of unqualified test items. In order to save costs, manufacturers use poor conductor materials, resulting in the current carrying capacity of the product is difficult to meet the requirements of national standards. The conductor resistance (20℃) is not qualified, which leads to easy overheating and combustion during use, and the power loss is large.

      Secondly, the tensile strength project before and after insulation aging does not meet the requirements, mainly because manufacturers use poor insulation materials to save costs, which will cause the service life of wire and cable to be greatly reduced.

      In addition, the tensile strength of the sheath before and after aging is also worthy of attention. The tensile strength project before and after the aging of the sheath does not meet the standard requirements, mainly because the manufacturer uses poor sheath materials to save costs, which will cause the service life of the wire and cable to be greatly reduced.
