第三季度，陕西省质量技术监督局对钢筋，防水卷材，电线电缆，PVC型材和其它建材产品质量监督抽查实施。检查结果表明，电线电缆质量问题，以不到4成的合格率。

总随机电线电缆企业51个，通过测试的51合格样品18个，35.3％的批次合格率已批样品。主要问题是导体电阻，在紧张的测试老化，绝缘老化前机械性能项目的失败。导体电阻测量性能标准值大于标准值，它的失败，使电缆容易受热，导致加速绝缘层老化。拉力预老化试验，绝缘老化前的力学性能，前鞘失败的机械性能老化，反映了企业的生产过程，原材料的利用存在的问题，其潜在危害是很容易的电线电缆使用绝缘层或护套出现破裂，导体，因此泄漏的危险。此外，个别产品，绝缘厚度，护套厚度，平均外径，存在这一问题的平均尺寸未能反映在绝缘材料，以节省生产企业，而不是标准组织，以及生产技术水平的生产问题。

此外，防水膜合格率百分之93.8，主要问题是紧张，断裂伸长率项目失败，PVC型材（型材）合格率82.4％，还有一个主要质量问题是规模后的变化率供热，该项目的拉伸冲击强度失败。

Shaanxi third quarter of wires and cables passing rate of low-quality spot checks

The third quarter, the Shaanxi Provincial Quality and Technical Supervision of reinforced, waterproofing membranes, wires and cables, PVC profiles and other building materials product quality supervision and spot checks carried out. Inspection results showed that the quality of wire and cable problems, with a pass rate of less than four into.

The total random wire and cable enterprises 51, 51 batches of samples taken by testing 18 batches of samples qualified, a pass rate of 35.3%. The main problems are conductor resistance, aging before the tension test, insulation aging of mechanical properties before the project failed. Conductor resistance performance standard for measuring value is greater than standard value, and its failure to make the cable easy to heat, resulting in accelerated aging of the insulating layer. Rally pre-aging test, before the mechanical properties of insulation aging, aging before the mechanical properties of sheath failure, reflecting the enterprises in the production process, raw materials, the use of existing problems, its potential harm is easy to wire and cable in use insulating layer or sheath appears broken , conductor and so the risk of leakage. In addition, the existence of individual products, insulation thickness, sheath thickness, with an average outside diameter, the average dimensions of the problem failed to reflect the enterprises in the production of insulating materials in order to save, not standards organizations as well as the production technology level of production problems .

In addition, the waterproofing membrane to 93.8 percent passing rate, the main problems are tension, fracture elongation project failed; PVC profiles (PVC Profile) pass rate of 82.4%, there is the main quality The problem is after the size change rate of heating, tensile impact strength of the project failed.
