购买电线时怎样鉴别优劣
国家已明令在新建住宅中应使用铜导线。但同样是铜导线,也有劣质的铜导线,其铜芯选用再生铜,含有许多杂质,有的劣质铜导线导电性能甚至不如铁丝,极易引发电气事故。市场上的电线品种多、规格多、价格乱,消费者挑选时难度很大。单就家庭装修中常用的2.5平方毫米和4平方毫米两种铜芯线的价格而言,同样规格的一盘线,因为厂家不同,价格可相差20%~30%。至于质量优劣,长度是否达标,消费者更是难以判定。
据业内人士透露:电线之所以价格差异巨大,是由于生产过程中所用原材料不
同造成的。生产电线的主要原材料是电解铜、绝缘材料和护套料。原材料市场上电解铜每吨在5万元左右,而回收的杂铜每吨只有4万元左右;绝缘材料和护套料的优质产品价格每吨在8000元~10000元,而残次品的价格每吨只需4000元~5000元,差价更悬殊。另外,长度不足,绝缘体含胶量不够,也是造成价格差异的重要原因。每盘线长度,优等品是100米,而次品只有90米左右;绝缘体含胶量优等品占35%~40%,而残次品只有15%。通过对比,消费者不难看出成品电线销售价格存在差异是材质上存在猫腻所致。
1、外力损伤。由近几年的运行分析来看,尤其是在经济高速发展中的上海浦东,相当多的电缆故障都是由于机械损伤引起的。
2、绝缘受潮。这种情况也很常见,一般发生在直埋或排管里的电缆接头处。比如:电缆接头制作不合格和在潮湿的气候条件下做接头,会使接头进水或混入水蒸气,时间久r在电场作用下形成水树枝,逐渐损害电缆的绝缘强度而造成故障。
3、化学腐蚀。电缆直接埋在有酸碱作用的地区,往往会造成电缆的铠装、铅皮或外护层被腐蚀,保护层因长期遭受化学腐蚀或电解腐蚀,致使保护层失效,绝缘降低,也会导致电缆故障。化:单位的电缆腐蚀情况就相当严重
4、长期过负荷运行。超负荷运行,由于电流的热效应,负载电流通过电缆时必然导致导体发热,同时电荷的集肤效应以及钢铠的涡流损耗、绝缘介质损耗也会产乍附加热量,从而使电缆温度升高。
5、电缆接头故障。电缆接头是电缆线路中zui薄弱的环节,由人员直接过失(施工不良)引发的电缆接头故障时常发生。施工人员在制作电缆接头过程中,如果有接头压接不紧、加热不充分等原因,都会导致电缆头绝缘降低,从而引发事故。
6、环境和温度。电缆所处的外界环境和热源也会造成电缆温度过高、绝缘击穿,甚至爆炸起火。
