残冬矿用铠装控制电缆无为

Non-combustible mineral insulated cables may be used in oil tank areas, public buildings with important wooden structures, high temperature places, and other situations where fire resistance re are high and installation is acceptable and economic performance is acceptable. When the self-capacity oil filled cable is applied to the public corridor, passenger tunnel, bridge and other situations re fire prevention treatment, it can be buried in sand. Close to the cable trench of high voltage current, voltage transformer and other oil-bearing e, it is advisable to seal the trench cover plate in this section.
　　企业于2001年率先通过ISO9001：2000国际质量体系认证。通信电缆具有泰尔认证中心颁发的产品认证证书。2002年我厂生产的煤矿用阻燃通信电缆，通过了国家煤炭部安全标志办公室的企业必须条件审查和产品安全性能检测。

　　9、外护（适用于铠装电缆23、22、53型）：在铠装层上挤塑一层聚乙烯或聚氯乙烯。10、可根据用户要求提供防防鼠、白蚁及阻燃等功能电缆。市内通信电缆用途：主要用于传输音频、150kHZ及以下的模拟信号和2048kbit/s及以下的数字信号。

Electrical strength of insulation: 1min 1kv between conductors does not break the conductor and the shield 1min 3kv does not break



　　2 电缆的使用特性、分类与命名2.1 使用特性2.1.1电缆额定工作电压：450/750V、600/1000V。2.1.2电缆导体的长期工作温度：70℃。2.1.3电缆敷设时环境温度应不低于0℃。2.1.4电缆小弯曲半径：非铠装电缆：阻燃型为电缆外径的6倍，耐火型为电缆外径的12倍；铠装型电缆为电缆外径的20倍。

PCB布局设计布局设计即是在PCB板框内按照设计要求摆放器件。在原理图工具中生成网络表（DesignCreateNetlist），之后在PCB软件中导入网络表（DesignImportNetlist）。网络表导入成功后会存在于软件后台，通过Placement操作可以将所有器件调出、各管脚之间有飞线提示连接，这时就可以对器件进行布局设计了。PCB布局设计是PCB整个设计流程中的首个重要工序，越复杂的PCB板，布局的好坏越能直接影响到后期布线的实现难易程度。
