Armoured Cable Earthing

Do We Need to Earth an Armoured Cable?

Safety in electrical installations comes first, and one important consideration that is sometimes ignored is the right earthing of armoured wires. Armoured cables play an important function in securely transferring power at this point. There are different applications and benefits of armoured cables, which fulfil major requirements like - safety and longevity for a cable. without proper earthing, they pose major safety risks. In this article, we will read the importance of earthing armoured cables, and why it is important.

What is the Importance of Earthing?

  • Safety for Individuals and Equipment: Earthing provides a safe path for electrical current to flow to the ground, preventing electric shocks and reducing the risk of electrocution. Earthing is crucial for keeping people and equipment safe.

  • Protection from Fire: Earthing systems direct excess electrical current safely to the ground, reducing the risk of electrical fires.

  • Voltage Stabilization: Earthing provides a common reference point for the electrical system, stabilizing voltages and improving the performance of electrical equipment.

  • Protection from Overlvoltage: when there's a sudden increase in voltage, like during a lightning strike, earthing provides a different route for that extra electricity to flow safely into the ground, reducing the risk of damage to electrical devices or systems.

How to Earth an Armoured Cable Properly?

To earth an armoured cable properly, follow these steps:

  • Prepare the Grounding Pipe: Proper grounding electrodes, such as grounding rods/pipes or plates, dig a hole deep enough to accommodate a grounding rod. These electrodes make sure that the cable's earth conductor is securely connected to the ground in the Earth.

  • Installation of Grounding Pipe: Insert the grounding rod vertically into the hole until it's securely in place. Ensure that at least two-thirds of the rod is buried underground.

  • The Connection between the Cable's Earth Conductor and the Grounding Electrode: To make sure the cable's earth wire connects well to the grounding electrode, the connection needs to be strong and have low resistance. Common methods like using the right clamps, connectors, and exothermic welding help achieve this.

  • Regular Maintenance: Regularly inspect and maintain the earthing system to ensure its effectiveness.

Let's end up with

Proper earthing of armoured cables is essential for ensuring safety in electrical installations. By providing a safe path for electrical current to flow to the ground, earthing prevents electric shocks, protects equipment from damage, and reduces the risk of fire hazards. Armoured cable manufacturers play an important role in providing high-quality cables that meet safety standards and facilitate effective earthing practices. Trusting a reputable armoured cable manufacturer ensures that you have the necessary components to implement a strong earthing system, safeguarding both individuals and equipment against electrical hazards.
