Some problems needing attention in the installation of control cable:

1. On the outer wall. Avoid direct sunlight on the wall and man-made damage. Heat - the temperature of cables in metal pipes or trunking is very high, and many polymeric materials will reduce their service life at this temperature.

2. Under the eaves. The cable can be used only when it is not directly exposed to sunlight or ultra-high temperature. It is recommended to use pipeline. Ultraviolet (UV) - do not use cables without UV protection in direct sunlight.

3. In the pipe (plastic or metal). If in the pipe, pay attention to the damage of plastic pipe and the heat conduction of metal pipe. Mechanical damage (repair cost) - the repair of optical cable is very expensive, and it needs to be terminated at least twice at each breakpoint.

4. Suspended application / overhead cable. Consider cable sag and pressure. What kind of bundling method are you going to use? Whether the cable is directly exposed to sunlight. 5. It is directly laid in the underground cable trench, which has a small control range. The installation of cable trench shall be regularly inspected for dryness or humidity. Grounding - if the shielding layer of the control cable needs to be grounded, the corresponding standards must be * * * observed. 6. Underground pipeline. In order to facilitate future upgrading, cable replacement and isolation from surface pressure and surrounding environment, auxiliary pipeline is a better method. But don't expect the pipe to remain dry forever, which will affect the choice of cable types.
