　　产品型号:KVVRP2-22--ZR-KVVRP2-22--ZR-KVVP2-22-R。产品展商:天津市电缆总厂第一分厂简单介绍：专业生产:KVVRP2-22--ZR-KVVRP2-22--ZR-KVVP2-22-R铜芯绝缘和护套铜带屏蔽钢带铠装（阻燃）控制电缆。

　　主要用於管道敷设。在缆芯中和屏蔽层的内外表面用石油膏填充和浇注处理，以防止水分侵入。在一30~C一60~C的环境条件下，电缆的机械和电气性能保持不变。结构：导线：退火裸铜线，铜线直径为0．40，0．50，0．60，0．70，0．80，0．90(mm)。

三联三开：意为三个开关可以控制三个用电器。三开单控就是面板上有三个开关，每个开关有两个接线柱，可以控制一路电；三开双控：三开双控就是面板上有三个开关，每个开关有三个接线柱，可以控制两路，向上扳控制一路，向下扳控制另一路。意为可控制三个用电设备,且可以双向控制.比如楼下与楼下,人从一楼开灯上二楼,,如果没有双控开关的话,那一楼的灯岂不是经常在亮而耗电,而有了双控开关后,在一楼开灯后,上了二楼后可按双控开关进行关灯,从而省去了耗电的损失。

　　 普通双绞屏蔽型电缆 STP-120Ω（for RS485 CAN） one pair 18 AWG ，灰色护套，电缆外径8.2mm左右。适用于室内、管道及一般工业环境。使用时，屏蔽层一端接地。

　　同轴电缆（视频线，监控线，射频线）同轴电缆从用途上分可分为基带同轴电缆和宽带同轴电缆（即网络同轴电缆和视频同轴电缆）。同轴电缆分50Ω基带电缆和75Ω宽带电缆两类。基带电缆又分细同轴电缆和粗同轴电缆。基带电缆仅仅用于数字传输，数据率可达10Mbps。
