What is the difference between ZR-RVV and ZR-KVV cables?
This is subject to site conditions and the use of cables. In a construction encountered in the cable tray in the cable need to wear pipe problems. Laying the cable is a manufacturer of coal powder leak detection equipment signal line. It was the first time that this problem was encountered. Requirements: 1: the line voltage level is very low, and very long, and requires a very accurate transmission (such as network lines), this time in order not to make the same line of other lines affect its signal transmission, is needed (And if the metal tube) 2: or the line of the voltage level is very high, and with the trough there are many low voltage level signal line, then wear it a good. The bridge within the cable can not wear steel pipe, of course, the bridge is also allowed to wear a line of steel pipe installation, the bridge can be empty according to the number of cable design requirements, when the line a lot of large bridge should be the main line, The branch line of the household or into the equipment can be flexibly accessed through the steel pipe.
Do not need, but if sometimes according to the engineering drawings to set the strong and weak in a bridge, the middle of the partition with a partition
No need, but if the strong and weak in a bridge, the middle of the partition to use separated.
