型号对数标称截面mm2导体结构根数/直径mm20℃时导体电阻不大于Ω/km适用范围本产品适用于冶金、石油、化工以及发电厂等工矿企业，在高温条件下和恶劣环境中（如酸、碱、油水低温条件）作为各种电器、仪表及自动装置之连接线，供交流额定电压450/750伏及以下控制、监控及保护电路行装场合下使用。
Call communication cable product features low cable of rated voltage: the minimum working temperature is not lower than 500 v low cable - 40 ℃. The highest long-term low cable allows working temperature: polyethylene insulation is not higher than 70 ℃; Cross-linked polyethylene insulation is not higher than 90 ℃. Low cable temperature: the minimum 0 ℃. Preheat if below minimum laying temperature. 's main electric cable performance: (l) 20 ℃ conductor dc resistance: 0.75 was no more than 26 / km; 2.0 was no greater than 9.8 Ω/km (2) 20 ℃ when the cable insulation resistance: 0.75 was not less than 300 m Ω • km; 2. Om Ω • Omm2 not small to 10 km. (3) voltage test between cable core and cable core, and between wire core and shield through ac 2500V/5min. (4) the working capacitance of the cable set shall not exceed 100pF/m when the test frequency is 1kHz. (5) the capacitance imbalance of the cable set shall not be greater than 250pF when the test frequency is lkHz and the cable length is 250Im. The combustion characteristics of the ending cable
This is the flame retardant of a single cable. Test rules, a 60 cm long specimen vertically fixed on the wall before the metal cabinet, flame length is 175 mm of propane fixed end 450 mm from the top of the samples from the position of flame cone and cable with 45 degree Angle, if damaged part sample distance lower fixed end no more than 50 mm, through. Iec 60332-3/ bs40666-3 flame retardant rating (bunched wire or cable vertical)
自承式电缆芯结构：以25对为基本单位，超过25吃饭的电缆按单位组合，每个单位规定色谱的单位扎带绕扎，以便识别不同的单位。100对及以上的电缆加有1%的预备对。自承式电缆缆芯包带：用聚酯薄膜带绕包。自承式电缆屏蔽：用轧纹或不轧纹金属带纵包子缆芯包带之外，两边搭接。
安防监控系统布线设计涉及到视频监控线路、广播对讲线路、报警线路、声音监听线路、网络线路。它们的功能作用不同，选择线缆的型号也不相同，今天我们就来讲讲电视监控系统需要涉及到哪些线缆：摄像机视频信号传输线缆常用的视频传输线缆为75系列的细同轴电缆，但是不同线径的同轴电缆对视频信号的衰减程度也是不一样的，线缆越粗、衰减越小。同轴电缆系列的特性参数如表1所示。要求依据表1选择线缆。电缆的线径越粗则衰减越小，越适合长距离的传播。
（4）保护层保护层的作用是保护电力电缆免受外界杂质和水分的侵入，以及防止外力直接损坏电力电缆。电子计算机用屏蔽电缆，选用介电常数小的高压聚乙烯作绝缘。型号/名称/性能型号电缆名称敷设方式DJYPV铜芯聚乙烯绝缘，对绞铜丝编织屏蔽，聚氯乙烯护套电子计算机电缆1、固定敷设在室内、电缆沟或管道内。
Power cables have many advantages and occupy less land. Generally, it is buried in soil or laid in indoor, ditch and tunnel. The insulation distance between lines is small. High reliability. It is less affected by climatic conditions and surrounding environment, stable transmission performance and high reliability. It has more favorable conditions for the development of ultra-high voltage and large capacity, such as low temperature, superconducting power cable, etc. The distributed capacitance is large. Less maintenance. It's less likely to shock.
