Control cable is a kind of cable to protect the circuit, the main material of this cable is polyvinyl chloride, because this material has good insulation performance, this cable can work normally under the rated 450/750 volts, so it can control the operation of the circuit well. The use of control cables is very wide, including some factories and mining enterprises and large energy sectors.

Third, control cable installation and wiring precautions:

1. Under the roof. Cable only when not directly exposed to sunlight or ultra-high temperatures, standard LAN cables can be applied, it is recommended to use pipes. Ultraviolet (UV)- Do not use cables without UV protection in direct sunlight.

2. Exterior wall. Avoid direct sunlight on the wall and man-made damage. Heat - The temperature of the cable in the metal pipe or groove is very high, and many polymeric materials will reduce the service life at this temperature.

3. In pipes (plastic or metal). Such as in pipes, pay attention to the damage of plastic pipes and the thermal conductivity of metal pipes. Mechanical damage (repair costs)- Cable repair is very expensive and requires at least two terminations at each break point.

4. Suspension application/overhead cable. Consider the sag and pressure of the cable. Whether the cable is directly exposed to sunlight.

5. Directly laid in the underground cable trench, this environment is small control range. The installation of cable trench should be regularly checked for dryness or humidity. Grounding - If the shielding layer of the control cable needs to be grounded, the corresponding standards must be followed.

6. Underground pipes. In order to facilitate future upgrades, cable replacement and isolation from surface pressure and the surrounding environment, auxiliary pipes are isolated, and auxiliary pipes are a better method. But don't expect the pipe to stay dry forever, which will affect the choice of cable type. Water - In a LAN twisted pair cable, moisture increases the capacitance of the cable, which reduces the impedance and causes near-end crosstalk problems.
