How to ensure cables’ performance in outdoor

Cable installations face the problem of how to efficiently transmit data in a campus environment. Routing, transmission distance and application environment all affect the choice of cable media. Incorrect or inappropriate selection can result in a limited period of cabling investment, and re-installation can cause system operations to cease.

Therefore, cabling system designers must consider the application environment, including the following environments and parameters that affect the cable.

Whether the cable is placed: under the eaves. Standard LAN cables can be used as long as the cables are not exposed to direct sunlight or high temperatures. Pipeline is recommended:

on the outer wall. Avoid direct sunlight on the walls and man-made damage;

in pipes (plastic or metal). For example, in the pipes of power copper power cables, pay attention to the damage of plastic pipes and the heat conduction of metal pipes;

Suspended applications/overhead cables (eg AAC ACSR AAAC). Consider cable sag and stress. Which bundle will be used. Whether the cable is directly exposed to sunlight; it is directly laid in the underground cable trench, which is the smallest control area. Cable trenches should be installed regularly and checked for dryness or humidity;

underground pipeline. Laying pipes is a great way to upgrade in the future, replace cables, and isolate from surface pressure and the surrounding environment. But don't expect the pipes to stay dry forever, that will affect the choice of cable type.
