That, when burned, fire-resistant cable less acid gas smoke, fire flame retardant performance is greatly improved, especially when burnt, accompanied by water jet and mechanical blow, cable still can maintain a full operation.
对于一般的家庭而言，4平方的电线就足够使用了，当然，在有特殊需要的时候，可以购买6平方电线。对于那种过大型电器，像是空调，可以独立电线出来供其使用。为了确保用电安全，就需要在电线上安装一个防漏电的开关，这样就能做到双重的安全保障。电线的平方数大致可分为2.5平方、4平方、6平方这三种。电线越粗，也就说明它的平方数越大。有的人认为电线是越粗越好，但实际上却不是这样。我们应该根据实际需要来选择电线的平方数。
绝缘材料：高密度聚乙烯或聚丙烯，按照全色谱标准标明绝缘线的颜色。绝缘线对：把二根不同颜色的绝缘线按不同的节距扭绞成对，并采用规定的色谱组合以便识别线对。缆芯结构：以25对为基本单位，超过25对的电缆按单位组合，每个单位用规定色谱的单位扎带绕扎，以便识别不同的单位。
这样本公司的交联聚乙烯电力电缆的整体水平低于国内领先地位。本公司生产的耐火型电力电缆为额定电压0.6/1KV铜芯电缆，还可以生产低烟无卤耐火电力电缆、高阻燃隔氧层耐火电力电缆，其耐火性能符合GB/T12666.6《电线电缆耐火特性试验方法》。
而且电缆的抗干扰性能高、电气性能稳定。保证了传输信号参数的准确性和控制系统的安全运行。阻燃变频电缆产品用途阻燃变频电缆主要用于变频电源和变频电机之间,连接用的电缆,以及额定电压1KV及以下的,输配电线路中,作输送电能用.尤其适用于造纸、冶金、金属加工、矿山、铁路和食品加工等行业。

RS-485为半双工，只有一对平衡差分信号线，不能同时发送和接收。使用RS-485通信接口和双绞线可组成串行通信网络(见)，构成分布式系统，系统中最多可有32个站，新的接口件已允许连接128个站。RS-485接口多用双绞线实现连接。个人计算机一般不配RS-485接口，但工业计算机配备RS-485接口较多。plc的不少通信模块也配用RS-485接口。如西门子公司的S7系列CPU均配置了RS-485接口。
100对及以上线对的电缆加有1%的预备线对，但最多不超过6对。缆芯内的间隙用石油膏填充。5、缆芯包带：用聚脂薄膜带绕包。6、屏蔽：铜丝屏蔽或用轧纹(或不轧纹)金属带，金属带纵包于通信电缆缆芯包带之外。7、护套：蓝色低密度聚乙烯。
钢带表面经涂塑处理，以防腐蚀和水份侵入。23，22型采用双层钢带绕包也有相似的性能。铠装通信电缆护套：黑色高分子量低密度聚乙烯或聚氯乙稀护套。护套厚度可取决于基本电缆外径。识别和长度标记：电缆外表有**性识别标记，标记间间隔不大于1m，铠装通信电缆标记内容有：导线直径、线对数量、电缆型号、长度、制造厂厂名代号及制造年份。
可靠接地时整个485线路的地线必须要有良好的接触，从而保证电压一致，因为在实际施工中，为了接线方便，将线剪成多段再连接，但是没有将屏蔽线作良好的连接，从而使得其地线分成了多段，电压不能保持一致，导致共模干扰。
