Common Causes of Cable Failure and How to Prevent Them

Electrical cable failure can lead to power outages, equipment damage, and even fires. Let’s examine the most common causes and how to avoid them.

1. Mechanical Damage

Improper handling or installation can kink or crush cables. Use protective conduits and avoid sharp bends.

2. Overheating

Running current beyond rated capacity overheats cables. Always match cable size to the expected load.

3. Moisture Ingress

Water entry can corrode conductors and short circuits. Use waterproof cables in damp or underground environments.

4. Chemical Exposure

In factories, chemicals can degrade insulation. Choose cables with chemical-resistant sheathing.

5. UV Degradation

Outdoor cables need UV protection. Otherwise, insulation may crack over time due to sunlight.

Conclusion

Preventing cable failure starts with correct selection, proper installation, and routine inspection. A little care goes a long way in ensuring system reliability.
