屏南14X1.5MKVV32控制电缆现货落魄
电缆地线芯绝缘采用具有抗氧化性能的K型B类低密度聚乙烯。聚乙烯的绝缘电阻高,耐电压好,介电系数小和介质损耗温度和变频率的影响也小,不但能满足传输性能的要求,而且能确保电缆的使用寿命。为了减少回路间的相互串扰和外部干扰,电缆采用屏蔽结构。
同轴电缆SYV——实心聚乙烯绝缘,PVC护套,国标代号是射频电缆——又叫视频电缆.绝缘层物理特性不同:SYV是聚乙烯填充,介电常数ε=2.2-2.4左右;而SYWV也是聚乙烯填充。一般所指的视频线为电视有线,也可用作安防领域的监控摄像头用线。

通俗地讲,电线万一失火,能够把燃烧限制在局部范围内,不产生蔓延,保住其他的各种设备,避免造成更大的损失。阻燃电缆概述阻燃电缆的含义:在规定试验条件下,试样被燃烧,在撤去火源后,火焰在试样上的蔓延仅在限定范围内并且自行熄灭的特性,即具有阻止或延缓火焰发生或蔓延的能力。

一个开关有三个按钮,控制三个电灯,如何接线?开关上有三排孔第一排是L1a,L1b,L1c第二排是L0L0L0c,第三排是L2L2L2c,现有两根白线一根黄线,应该怎么接线呢?开关的L1L1L1c是封着的,不能接线。如果把一根白线和黄线接到L0a上,把另外一根白线接在L2a的左端,结果有一盏灯是正常的另外一盏从合闸开始就亮着,不受开关控制,这是怎么回事?答:三个开关控制三盏灯(每个开关控制一个灯),首先要有4根线才可以完成,一根电源线,接到三个开关的进线端(L0L0L0C,也就是说用进线把这三个点连在一起),把剩下的三根分别接到L2L2L2C,如果现在只有三根线,黄的可能是进线,白的就是2个灯的回路线,空着的就说明那个开关没有控制任何灯。
This product is suitable for communication lines in urban, suburban and local areas. Conductive core wire adopts soft copper wire with nominal diameter of 0.4, 0.5, 0.6, 0.7, 0.8 and 0.9mm. Twisted into the single wire insulation after the heart type (10, 20) or the unit type twisted into core (30 to and above), each basic unit of the unit with same color, the basic unit of cable tie color arrangement according to the re of the chromatography. On the surface of the cable core, a non-hygroscopic polyester belt or a non-woven cloth belt is used to wrap the cable core and then add the longitudinal package of the moisture-proof metal shield belt. The outer sheath can be made into polyurethane or chlorine sheath. The self-supporting cable is to squeeze the cable core and steel strand parallel to the same "8-character" calabash outer sheath. ?
Flame retardant cable, is refers to under specified test conditions, specimen was, after removed test of ignition, flame spread only in a limited range, residual sheep and burning in the finite cable to self extinguishing in the course of time. The fundamental characteristic is that it may burn out and not run in the case of fire, but it can spread fire. Generally speaking, in case of electric wire fire, it can be put in the local scope, not to produce spread, keep other kinds of e, avoid causing greater loss. The meaning of the flame retardant cable: under specified test conditions, samples were, in is removed after the fire, the spread of flame on the sample only in a limited range and the characteristic of self extinguishing, which has the ability of or delay the outbreak or spread of flame.
耐火电缆能保证在线路着火的情况下保持一定时间的正常工作。使用特性:保持电缆的原有特性不变。在一定条件下可用于传输2048kbit/s以上的数字信号。适用于城市、近郊及厂矿局部区域的电信线路中,电缆的工作环境温度为-30~+60℃,敷设环境温度不低于-5℃。
4.工作电容:平均值52±2nF/km5.远端串音防卫度:150kHZ时指定组合的功率平均值大于69dB/km。产品特性:电缆的额定电压:500V●电缆的低工作温度不低于-40℃.●电缆的高长期允许工作温度:聚乙烯绝缘不高于70℃;交联聚乙烯绝缘不高于90℃。

为了方便接线,生产厂家往往使用统一标准的接线板将电动机绕组线引出,如下图三所示,U1U2,V1V2分别为工作绕组和启动绕组,C为外接电容器,K为电动机内部的离心开关。电动机启动后,当转速达到80%时左右时,K断开,切除V1V2,工作绕组拖动负载运行。(图三)电机正转时,用连接片将U1与V1连接在一起,U2与Z2连接在一起。U1端接电源相线,U2端接电源你零线。如下图:(图四)电机反转时,用连接片将U1与Z2连接在一起,U2与V1连接在一起,U1端接电源相线,U2接电源零线。
Flame retardant cables and fireproof cables: the difference between the average person is very easy to confuse the concept of flame retardant cables and fireproof cables, although there are many more flame retardant cable applies to the advantages of chemical enterprise, such as low, low smoke, non-halogen, but in general, fire-resistant cable can replace flame retardant cable, and flame retardant cables can't take place of fire-resistant cable.
例如,常用的电话线直径为24AWG的线径约为0.5mm(0.2mm2),26AWG,约为0.4mm(0.13mm2),AWG数值越大线径越小,平方越小。如果传输距离达不到以上数字,除了布线环境干扰恶劣外,那就是电缆的质量问题。
