陕西省质量技术监督局在第三季度的钢筋，防水卷材，电线电缆，PVC型材和建材产品质量监督抽查，发现其他类型的随机电线电缆合格不到4成率。

电线电缆样品51批样品的只有35.3％的合格率。质量问题主要是导体电阻失败，或在78.8样本总数％失败，将测量值的性能标准比，这个指标的价值更大的失败，使电缆容易受热，导致加速衰老绝缘层。拉力预老化试验，在绝缘老化，机械性能，护套老化前机械性能不合格的失败为66.7潜在的危险，占总数的百分之容易电线电缆已在绝缘层或护套破裂，出现渗漏使用导体或其他危险。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失败。

Shaanxi: Quality Supervision random wires and cables passing rate of less than 40%

Shaanxi Provincial Quality and Technical Supervision in the third quarter of reinforced, waterproofing membrane, wire and cable, PVC profiles and other types of building materials products quality supervision and spot checks found that the random wire and cable pass rate of less than four into.

the wire and cable samples were 51 batches of samples, with a pass rate of only 35.3%. Quality problems are the main conductor resistance failed, or failed in 78.8% of the total number of samples, performance standards for the measurement value is greater than the value of this indicator failed to make the cable easy to heat, resulting in accelerated aging of the insulating layer. Rally pre-aging test, insulation aging before the mechanical properties, mechanical properties before aging jacket unqualified failure accounted for 66.7 percent of the total number of potential hazards are easy to wire and cable have emerged in the use of insulating layer or sheath rupture, leakage or other dangerous conductor. In addition, the existence of individual products, insulation thickness, sheath thickness, with an average outside diameter, the average dimensions of the problem failed. (07-11-26)
