Low voltage cable mainly use communication equipment, and some of the weaknesses of the telecom room transmission, low voltage cables and cable not clear boundaries. Low voltage cable brand also more, add nami, LingYu, new cui, akihabara, a boat, etc.

Low voltage cable is a naming rules, we can know from the name of the cable this low voltage cable is mainly used in what kind of situation, and the structure of the inside materials or his composition structure is the most important thing is that we can learn that have the characteristics of the cable. There are a lot of low voltage cable types and features, we have several kinds of common:

1, video cable, he shall, in accordance with the distance of surveillance cameras and monitoring machine is divided into two kinds of circumstances, closer than 200 metres with SYV75-5 cables. Cameras and monitoring machine at a distance of more than 200 meters to use SYV75-5 cables;

2, yuntai control line, he is also divided into two kinds, yuntai in controller are less than 100 meters with RVV6 * 0.5 sheathed wire. Yuntai in controller are more than 100 meters with RVV6 * 0.75 sheathed wire;

3, decoder, communications lines, and using RVV2 * 1 is shielded twisted-pair cable.

4, the lens control line, use is RVV4 * 0.5 sheath line:

Lots of weak current cables of low voltage cable they classification, so when selecting need according to what we use to choose equipment, we also according to what we use situation and distance to choose.
