BV line, BVR line, RVSP double stranded shielded cable, RVS double stranded cable, RVB parallel line, RV line RVSP Shielded twisted-pair cable RVSP (shielded twisted-pair cable, shielded cable, shielding twisted-pair electric (HYVP, RVVP) RVVP twisted-pair shielded cable < < shielded wire > > is shielded twisted-pair cable RVSP series on the basis of RVS coupled with a layer of copper wire shielding net, so the transmission loss, shielding the outside world better than RVS series, but because of the copper wire shielding network, its cost is also much higher than RVS series. Are often used to those who has a high requirement on the transmission. Technical indicators: polyvinyl chloride insulated cable long-term allowed working temperature over 70 ℃, the cable temperature under installation should not below 0 ℃, outer diameter (D) is less than 25 The allowable bending radius of mm cable shall not be less than 4 times the outer diameter of the cable. Diameter (D) of 25 mm and above of permissive bending radius of cable, not less than 6 times of cable diameter.

导线弯曲应一致,且不得有死弯,防止损坏导线绝缘皮及内部铜芯。第一排零线第二排零线配线A相线为黄、B相线为绿、C相线为红。照明及插座回路一般采用2.5mm2导线,每根导线所串连空开数量不得大于3个。空调回路一般采用2.5mm2或4.0mm2导线,一根导线配一个空开。由总开关每相所配出的每根导线之间零线不得共用,如由A相配出的第一根黄色导线连接了二个16A的照明开空,那这两个照明空开一次侧零线也是只从这二个空开一次侧配出直接连接到零线接线端子。
0.5-1.5mm21-84对(3线组)用于电子控制装置、自动化系统、数字验检、计算机回路及其它一般工业计算机检测装置上。同轴电缆是专门设计用来传输视频信号的,其频率损失、图像失真、图像衰减的幅度都比较小,能很好的完成传送视频信号的任务。

现在将一些错误的观念作出一些澄清。1.485信号线可以和强电电源线一同走线。在实际施工当中,由于走线都是通过管线走的,施工方有的时候为了图方便,直接将485信号线和电源线绑在一起,由于强电具有强烈的电磁信号对弱电进行干扰,从而导致485信号不稳定,导致通信不稳定。
