Common faults of luminous cables in armor land

Armored cables are widely used in various industries for their robustness and durability. The armor layer provides additional protection to the cable, making it suitable for use in harsh environments. However, armored cables are susceptible to faults that can lead to downtime, which can be costly for businesses. In this article, we will discuss common faults in armored cables and how to prevent them.

Common Faults in Armored Cables

Corrosion

Corrosion is one of the most common faults in armored cables. The armor layer is usually made of steel, which is prone to corrosion when exposed to moisture and other environmental factors. Corrosion can weaken the armor layer and compromise the overall integrity of the cable.

Mechanical Damage

Armored cables are designed to withstand harsh environments, but they can still be damaged due to mechanical stress. Mechanical damage can occur during installation, handling, or due to environmental factors such as vibrations or impacts. This damage can lead to cable failure and downtime.

Cable Crush

Cable crush occurs when the armor layer is deformed due to external pressure. This pressure can come from heavy machinery or equipment, or from vehicles running over the cable. Cable crush can cause the armor layer to collapse, damaging the inner components of the cable and leading to downtime.

Moisture Ingress

Moisture ingress is a common fault in armored cables that can lead to cable failure. Moisture can enter the cable through gaps in the armor layer, which can cause the insulation to deteriorate and damage the conductors. Moisture ingress can also lead to corrosion, which can weaken the armor layer and compromise the overall integrity of the cable.

Preventing Common Faults in Armored Cables

Corrosion Prevention

To prevent corrosion in armored cables, it is important to use the right materials for the armor layer. Stainless steel is a good option as it is resistant to corrosion. Additionally, regular inspections and maintenance can help identify corrosion early and prevent it from spreading.

Mechanical Damage Prevention

Mechanical damage can be prevented by ensuring that the cable is installed and handled correctly. It is important to follow the manufacturer's installation guidelines and use proper tools and equipment to avoid damaging the cable. Cable ties or clamps can also be used to secure the cable and prevent movement that can lead to mechanical damage.

Cable Crush Prevention

Cable crush can be prevented by using cable protection systems such as cable trays, conduit, or ducting. These systems provide additional support to the cable and prevent external pressure from damaging the armor layer. Additionally, installing warning signs to indicate the location of the cable can prevent vehicles from running over it.

Moisture Ingress Prevention

Moisture ingress can be prevented by using a water-resistant barrier between the armor layer and the inner components of the cable. This barrier can be a layer of water-blocking tape, or a water-blocking gel. Additionally, regular inspections and maintenance can help identify gaps in the armor layer that can allow moisture to enter the cable.

Conclusion

Armored cables are designed to withstand harsh environments, but they are still susceptible to faults that can lead to downtime. Corrosion, mechanical damage, cable crush, and moisture ingress are common faults that can compromise the overall integrity of the cable. Preventing these faults requires using the right materials for the armor layer, following installation guidelines, using cable protection systems, and regular inspections and maintenance. By taking these preventative measures, businesses can ensure that their armored cables remain reliable and durable.
