六个问题了解家装电线
1. 为什么要买不?ldquo;平方”的电线?
电线平方数是水电工的口头用语?ldquo;平方”指的是标称截面积为多少平方毫米。因电线的承载量不同,大功率电器需配备?ldquo;平方”的电线?br />
照明线路?.5平方? 插座?.5平方?br />
空调/热水?浴霸?平方? 中央空调/进户总线?平方?br />
家装过程中,电线的平方数也非越大越好,综合经济等各项因素,合理听取电工的建议,做到物尽其用?/span>
2. 不同颜色电线用?/strong>
火线L:红色(黄色备用?br />
零线N:蓝色(黄色、绿色备用)
地线PE:黄绿双?br />
电线颜色是为区分不同相位,便于施工及后续检修?/span>
3. 3C认证那点事儿
答:
?nbsp; 3C认证的全称为“强制性产品认证制?rdquo;,是我国政府为保护消费者人身等安全制定的产品合格评定制度?C标志并不是质量标志,而只是一种最基础的安全认证?br />
?nbsp; 生活中接触到的家用电器(空调、电视、电脑)、汽车(轮胎、玻璃)、玩具等均需要进?C认证?br />
?nbsp; 电线电缆中有5种在目录中,需要进?C认证,例如额定电?50/750 V及以下聚氯乙烯绝缘电线电缆。不在目录中的则不需要进?C认证,例如交联聚烯烃绝缘电线电缆?br />
万阳电缆有限公司 3C证书编号2016010105923560
4. 你该了解的绝缘层
?nbsp; 无卤低烟系列:电线的绝缘层材料在燃烧的情况下,不释放含卤气体,烟雾浓度低?br />
?nbsp; 阻燃系列:阻燃效果依次ZA>ZB>Z( C ),A类阻燃最为严格,B类阻燃要求较高,适用于对阻燃要求较为严格的场合,C类为一般阻燃,适用于大多数场所?br />
?nbsp; 绝缘材料:直接包裹导体的部分是绝缘层,市面上常见的是BV/BVR和BYJ /BYJR电线,V表示绝缘层材质为聚氯乙烯(PVC),YJ表示绝缘层材质为交联聚烯烃;
WDZ-BYJ/WDZ-BYJR 的含义:WD表示无卤低烟;Z表示C类阻燃(ZA表示A类阻?; ZB表示B类阻? 缺省表示C类);B表示固定布线用电线;YJ表示交联聚乙烯绝缘;R表示连接用软电线。无卤、低烟、阻燃同时具备优良的短路负载能力,型号中含N的表示具有耐火特性?br />
H07Z-U/H07Z-K的含义:H表示欧洲协调标志?07表示450/750V ;Z表示无卤低烟聚烯烃交联;U:硬导体?类导体;K:软导体?类导体;
5. 欧标并不神秘
产品最终的质量一般由设计、材料、设备等组成,电线中设计质量取决于采用的标准,欧标线缆标准在世界范围内都属于佼佼者。认证机构根据对应范围内的标准进行产品认证,就有了我们看到的CE(欧洲电气及其统一安全规格委员会)和TUV(德国莱茵技术监督协会)的认证标识?br />
产品质量核心为标准,认证标识起到锦上添花的作用。产品全称为辐照交联聚烯烃绝缘无卤低烟阻燃单芯硬导体/软导体无护套电缆,执行标准为EN 50525-3-41:2011,产品型号为H07Z-U / H07Z-K?/span>
6. 如何选择优质电线?/strong>
?nbsp; 品牌:选择规范大厂生产的产品,?ldquo;天眼?rdquo;“启信?rdquo;中查询厂家信息;
?nbsp; 电线外观:铜芯颜色光泽、无偏心,绝缘胶皮紧实均匀?br />
?nbsp; 标识:看有无质量体系认证书,看合格证是否规范,看有无厂名、厂址、检修章、出产日期,看电线上是否印有商标、规格、电压等?br />
万阳电缆有限公司采用具有优良导电性能、抗腐蚀性能的含铜量99.97%以上无氧铜杆制作导体
