二、用途
适用于交流电压为450/750V及以下的动力装置、日用电器、仪表及电信设备用的电缆电线。
阻燃型电缆（电线）的特点是不易着火或者着火后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类和Ｃ类三个级别，其中Ａ类阻燃性能***优。
耐火型电缆（电线）的特点是电缆除了能在正常的条件下传输电力外，还可以在燃烧的善下仍能保持一定时间的安全运行，其使用在对电缆特性有要求的场合。

Application
These cables are produced according standa*** GB 5023-199 and JB8734-1998, and to apply to electrical appliance, instrument and telecom device with rated voltage up to and including 450/750V.
The main features of the flame retardant PVC cable or wire is hard to get fire or that the continuous burning of cables is very limited when it is on fire. It applies to the places with special demands for flame retardant property. Flame retardant cables are classified as class A, B and C. Amongst the 3 classes, class A is the best.
Fire-resistance cable can operate normally for some time when it is burning except that it can tran***it electrical power under normal condition. It is used in the places with special demands for fire resistance property.
Features
1. Rated voltage U0/U is 450/750V, 300/500V,or 300/300V.
2. Permissible continuous working temperature of cable conductor:
-for mode of cable RV-90 and BV-90, the temperature should be not more than 90 centigrade degree.
-for others, the temperature should be not more than 70 centigrade degree.
3. Ambient temperature should be not less than 0 centigrade degrees, and permissible bending radius of cable for fixed connecting should be as follows during installation.
-for O.D. less than
-for O.D. not less than
4. Flame retardant cable should pass the test of bunched cables or wires under fire conditi*** which are described in the standa*** of GB/18380.3-2001.
5. Fire resistant cable should pass the test of fire resistant stipulated in the standa*** of GB/T 19216.21-2003.
