Li2YCY TP cables are stranded equipment wire for telecommunication systems
and data processing systems for long distance in a wide variety industry
areas such as automation, measurement, and instrument, etc. They are
suitable for transmission Data and low-level signal, especially for
RS422 or RS485 indoor in dry, damp and wet conditions. The twist pairs
are from a Loop, also reduce the cross-talk of each loop. The overall
tinned copper braid screen is provided to the good EMC properties. |
