a) Avoiding failures
b) Avoiding damage to the environment
c) Extend cable life
(d) Preventing accidents
e) Avoiding production losses
(f) Minimize public cost
(g) Improving the public image

The most common types of faults that occur in a cable are the following:
a) Mechanical damage to the cable or cover resulting from carelessness in an excavation
(b) Damage to the metal screen by corrosion or vibration
c) Water ingress to the joints
d) Excessive mechanical stress caused by earthquakes, soil settlements, thermal cycles, among others.
e) Thermal ageing of insulation.
What are the consequences?
Among the consequences of not giving a correct maintenance are:
Avoid damage to equipment
Avoid interruptions
Prevents accidents
Savings on repair costs

There are also tools that are available to try to avoid cable failures, which have to do with taking care of the following recommendations:
a) Cable routing inspection
b) Temperature measurement at critical points
(c) Measurement of partial discharges
(d) X-rays of accessories
(e) Measurement of the thermal resistivity of the terrain
f) Greater protection for cables and accessories
(g) Periodic electrical and thermal tests
(h) Provide information to third parties on the location of the cable route.
