电线电缆是用于传输电力、传输信息和实现电磁能量转换的一大类电工产品。在抽查过程中，发现了大量的不合格产品，这些劣质产品给电力系统正常运行埋下诸多隐患。
Wire
and cable are a large category of electrical products used for
transmitting power, information, and electromagnetic energy conversion.
During the random inspection process, a large number of substandard
products were discovered, which laid many hidden dangers for the normal
operation of the power system.
1、标志不合格的电线电缆。标志是电线电缆使用识别产品基本信息的主要途径，根据标准规定标志的主要内容是：产品型号、规格、标准号、厂名、产地等在一定的标示间距内，当标志不合格时，会造型线 流水槽模具 景观石 检查井钢模具 保定通风管道 隔离墩模具 保定保洁公司成施工人员识别错误，严重时会引发电气事故。
1.
Unqualified wires and cables marked. Signs are the main way to identify
the basic information of products when using wires and cables.
According to standard regulations, the main content of the signs is:
product model, specification, standard number, factory name, place of
origin, etc. Within a certain distance between the signs. When the signs
are not qualified, it can cause identification errors by construction
personnel, and in severe cases, it can lead to electrical accidents.
2、结构尺寸不合格的电线电缆。结构尺寸的主要问题是护套厚度，绝缘厚度，当电缆的护套和绝缘厚度不达标时，致使电线电缆耐电气强度会严重降低，导致电线电缆的使用寿命缩短，严重时可导致电线电缆被击穿，绝缘（护套）层起不到正常保护作用，从而发生电气短路和火灾等现象。
2.
Wire and cable with unqualified structural dimensions. The main problem
with structural dimensions is the thickness of the sheath and
insulation. When the sheath and insulation thickness of the cable do not
meet the standard, the electrical strength of the wire and cable will
be severely reduced, leading to a shortened service life of the wire and
cable. In severe cases, it can lead to the breakdown of the wire and
cable, and the insulation (sheath) layer cannot play a normal protective
role, resulting in electrical short circuits and fires.
