塑料绝缘控制电缆(Plastic insulated control cables)
一、产品特点及用途
塑料绝缘控制电缆适用于交流额定电压U0/U 为450V/750V 及以下控制、监控回路及保护线路等场合,作为设备之间的控制接线。
阻燃控制电缆的主要特点是电缆不易着火或着火时延燃仅局限在一定范围内,适用于对阻燃性能要求较高的场合。
耐火控制电缆的主要特点是电缆除了能在正常的工作条件下传输电力外,电缆在着火燃烧时仍能保持一定时间的正常运行,适用于对耐火特性有要求的场合。
二、产品标准
本产品按GB9330-88标准生产,还可按用户要求的其他标准生产。阻燃电缆除按上述标准外,其阻燃性能按GB/T19666-2005标准规定分成A、B、C三种不同的阻燃类别。***类别的阻燃性能***优。用户可根据需要选用。

Characteristics and Application
Plastic insulated control cables general is used to connect electrical equipments. It applies to controlling, monitoring and protective system with A.C.rated voltage U0/U up to and including 450/750 volts.
The main features of the flame retardant PVC control cable are 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 of flame retardant property.
Fire-resistance cables can operate normally for some times when it is burning except that it can tran***it electrical power under normal condition. It is used in the places necessary to resist fire.
Standa*** of products
The cables are manufactured in accordance with the standard of BG9330-88. They can also be produced according to special requirements put forward by clients.
Besides the standa*** mentioned above, the flame retardant property of the flame retardant cables must meet the corresponding demands of class A, B or C which is stipulated in GB/T19666-2005. Among the 3 classes, class A is the best. Clients can select any type of cables as practical needs.
Fire-resistance property of the fire-resistance cables meets standard GB/T1921621-2003
