如何辨别劣质电线?

伪劣电线的危害

电线火狐体育app官网是关系到千家万户的生命财产安危和几乎所有行业能否正常运行的特殊商品,使用范围极为广泛,尤其在临时用线和家庭装修室内用线上使用量非常大,如果使用了假冒伪劣的电线电缆,轻的可能造成短路、触电,重的可能引发火灾,造成人员伤亡。2009年底云南省工商局的抽检结果表明省内流通领域近六成的电线电缆不合格,市面上近五成的电线电缆的心脏部位——铜芯存在偷工减料现象。云南消防部门的粗略统计数据表明,近年来超过四成的火灾由电器故障引发,铜芯“缩水”的黑芯电线电缆是主要原因之一。

伪劣电线的特征

1、DIANLANZHANGDUBUGOU

不法厂家惯用的主要手段就是在电线电缆长度上作文章,电线电缆实际长度小于标称长度,而计价收费则按照标称长度执行。最为典型的就是成卷包装的布电线,在国家标准中规定每卷100米,计量误差不大于0.5%,也就是每卷线的长度为100±0.5米,而许多厂家则明目张胆的在合格卡上标注100±20米,其实际长度只有80米左右,如果其售价折合到每米,则并不便宜。此类骗术较容易识别,一是看合格卡;二是抽检长度,因为布电线相对较柔软,测量容易。

伪劣电线的鉴别

1、看标签。正规厂家生产的电线合格证的内容应包括:3C认证标志、认证编号、型号规格、执行标准、额定电压、电线长度、生产日期、生产者、检验者、厂名、厂址、固定电话、防伪标示等。而假冒产品的标签往往印刷不清或印制内容不全。

根据以上几个简单的验证方法,基本能识别它是否为优劣的电线。如果你需要用数据说话,请用相应的仪器检测电线的长度、直径、厚度、电阻、耐压以及强度。
