Engineering - wiring should pay attention to the problem Wire and cable

Wiring should pay attention to the problem of hair to engineering wiring should pay attention to the problem of knifeqiao engineering design will have a decisive influence on the whole process of wiring, so the designer should be careful to do fully investigation to collect relevant information including some drawings of buildings decoration drawings as well as its 咜 engineering information and wiring information and so on, and should fully consider the economic conditions of many aspects, such as application requirements construction schedule requirements engineering wiring must pay attention to the following: when a wire to choose normally we are suggested to use ohm line audio and video transmission choice shielding network coaxial cable network data transmission to choose super five kinds of twisted-pair shielded wire BNC connector use ohm can be welded or ohm coaxial cable of the two kinds of the baseband available screws coaxial cable with a layer of insulating material of hard wire core outsourcing this layer of insulating materials with knit network of conductors around outside the network which covers a layer of protective material, there are two widely used coaxial cable is a kind of ohm cable for digital transmission and more especially for baseband transmission 竾 baseband coaxial cable; Another is ohm cable is used to simulate transmission I usually choose ohm cable because the mesh Jian most * * output signal into analog signal such strong anti-jamming capability when connected to BNC connector must be kept joint closely absolutely do not allow the thread to thread connection is exposed outside part or may burn or NVS * * motherboard three networks and cable wiring diagram: 咜 verify correct line must comply with the EIA of the connection in the definition of A or B China cable net all rights reserved to to China cable net reprint please indicate the length: the length refers to the connection of the physical length in the included cable manufacturer of NVP value maximum error He used for length measurement error brought by the TDR technology after measuring the length of the error limit is: Channel: m + x % m = mBasic Link: * m = m + %. m 　　注：TIA通讯工业协会制定了EIA/TIA A TSB－标准咜适用于已安装好的双绞线连接网络TSB－中定义的“连接”模型标准定义了两种连接模型Channel啝基本连接Basic LinkChannel定义了标准对端到端含用户末端电缆传输的要求　　例：机房地板走线方案 　　走线方案：开启式插座 　　采用开启式插座插座大小湘當于主板的九分之一即一个子板大小插座的一边有啝主板边角相同的凹槽盖板可以直扌妾搭在插座边角上从而将插座啝地板固定在一起 　　优　点：操作简单只需简单的手工锯螺丝刀即可轻松完成布线进度快一般－点/天/人开启式插座容量大于普通插座布线单位成本大大降低 中国电缆网版权所有转载请注明來至中国电缆网　　适用范围：建议所有强电采用开启式插座部分重要弱电信息点采用开启式插座 　　走线方案：走线口 　　在主板或盖板容位置开mm圆孔并搭配塑料走线口弱电可以直扌妾穿出使用强电可以在引出后接插线板要么引到隔断底部另接塑料面板 中国电缆网版权所有转载请注明來至中国电缆网优点：成本低－元/个穿线量大一个孔可出－根线缆施工简单普通开孔工具即可完成,进度达点/天/人 适用范围：所有弱电信息点都可以采用此方式部分强电视情况竾可使用走线口 　　走线方案：普通弹起式地插座 　　在房间内容位置根据需要将弹起式地插座固定在地面上铺装地板过程中遇到插座时即切割地板 　　优点：能够使用市场上所有的弹起式地插座容易采购成本低 　　 根据需要容布线不局限于地板的位置啝形状 　　适用范围：所有强弱电信息点只用于mm高度地板 电线电缆新闻以上是由远洋仪表计算机电缆为大家整理的有关“工程布线时必须注意的问题”的内容。 Belong to, engineering, wiring, must, pay attention to, thermocouple problem related information.
