四、产品特点及用途 Product’s Characteristic and Application

交联聚乙烯绝缘控制电缆具有高机械强度、优良的电气性能和耐化学腐蚀等特点，重量轻，结构简单，使用方便。本产品适用于交流额定电压U0/U为450/750V及以下控制、监控回路及保护线缆等场合，作为电气装备之间的控制链接。

阻燃型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于在一定的范围内，适用于对阻燃性能要求较高的场合。

耐火型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，电缆在着火燃烧时扔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。

无卤低烟阻燃型控制电缆的特点是电缆不仅具备阻燃性能，而且具有低发烟性和无害性（毒性和腐蚀性较小），适用于对电缆阻燃、烟密度、毒性指数等有特别要求的场所，如核电站、地铁等。

XLPE insulated control cable has the advantage of not noly high mechanical strength, gond ambient stress resistance, excellent electrical properties and anti-chemical corrosion,but also simple construction, hight weight and easy to use. This type of cable is applicable for connection of electrical equipment,controling, monitoring and protective system with A.C. rated voltage UO/U up to and including 450/750V.

The main features of flame retardant control cable is not easy to carry the transmission of electricity under normal operating conditions,but also maintains normal operation for a period of time during fire burining. This cable is suitable for the occasion requied fire-resstance. The main characteristic of low smoke, halogen-free, flame retardant control are low smoke emssion and harmless(low toxic,low corrive) besides the property of flame retardant. It can be used in places such as subway, tunnel, nuclear power station with special requirement of flame retardant, smoke density and toxicity index.
