三、用途
适用于交流电压450/750V及以下装置、日用电器、仪表及电信设备的电缆电线。
阻燃型电缆(电线)的特点时不易着火或着火厚火焰蔓延较慢并能控制在一定的范围内，其使用于对阻燃性能要求较高的场合。阻燃电缆(电线)分为A类、B类、C类等三个级别，其中A类阻燃性能最优。
耐火型电缆(电线)的特点是电缆除了能在正常的工作条件下传输电力以外，还可以 在燃烧的状况下保持一定时间的安全运行。该电缆使用在对电缆特性有要求的场合。耐火电缆(电线)分为A类和B类二个级别，可根据不同的要求选择不同类别的耐火电缆。
低烟低卤电缆(电线)具有低烟、低卤的特点，可使电缆在燃烧时控制产生有毒的氯化氢气体和灰黑色的烟雾。该电缆使用在人员较密集的场合。

Applications
It applies to electrical appliances, instruments and telecom devices at a rated voltage up to 450/750 volts.
The main features of the flame retardant PVC cable or wire are hard to get fire or that the continuous burning of cables is limited when it is on fire. It applies to the places with special demands for flame retardant property. Flame retardant cable is classified as Class A, Class B and Class C. Among the 3 classes, Class A is the best.
Fire-resistance cable can operate normally for some time when it is burning, apart from that it can transmit electrical power under normal condition. It is used in the places with special demands for fire resistance property. Fire resistance cable has two classes like A and B. Clients can select one as their practical needs.
The main characteristic is low smoke and halogen. Flame retardant cables are low smoke emission and low release of HCL gas besides the property of flame retardant. It can be used in the places with special demands for the density of smoke emission and the release value of HCL gas when the cable gets burning.
