Armoured Wire
Armoured Wire | Armoured Wire From Sarbadaa
There are Various Advantages of which Come Along the Armoured Cables:
1. Temperature Resistance
Steel has a melting point of about 15000C which is very high in comparison to aluminium and copper. For these, the melting point is about 6000C and 10000C respectively. This simply shows that for protection steel goes a long way out. It is able to protect the electrical current-carrying conductors against very high temperatures. Therefore, the armoured cable 3 coredurability of the transmissions via cable components are armoured cable with steel. It actually makes armoured cables a good solution for industries. These cables and wires are manufactured as they are exposed to and are able to withstand variant temperatures

2. Advanced Mechanical Properties of Armoured Power Cable:
Cables that are of use in large industrial applications have a lot of challenges and issues at the time of transmission. Both the cables electrical and network are used for over long distances which directly exposes them to a lot of mechanical threats. These cables are placed overhead or underground as per the requirement. But whatever the case is these are exposed to direct mechanical damage.
Armoured cables are capable of protecting the inner components of the cable being used. Actual transmission can also be used from getting damaged by several external factors and thus hindering the transmission. It provides a surety that both power and network are available for the desired applications and thereby also making armoured cables and wires are reliable way of transmission.
3. EMI (Electromagnetic Interference)
We now have cables that are particularly used for the mains grid, it is important that interference from the fellow cables are in the path of the transmission line. Only because of the amount of high power which is transmitted, use of armoured wires & cables helps in providing insulation of transmission components from emitting the interference. It also protects from being affected by interferences caused by neighboring cables and also appliances.
Armored cables are better to be used in fixing conduit pipes as they are able to support by transporting large volumes of water over large distances.
Wiring done at places that pose a great danger to cables is a matter of concern and also their components such as locations with extreme weather conditions are likely to cause interference to the cables presently used.
What is an SWA? What are Its Uses?
- It is an auxiliary control and power cable which is mainly designed for use in the mains supply. SWA (Steel Wire Armoured ) cables are designed in order to give mechanical protection and this is the reason that cable is used for external purposes since Armour reduces the risk of any physical damage including being pinched or damaged; steel is generally used for protection of Armoured cable. Since wires and cables are heavy with respect to weight which makes them very difficult to bend, these are suitable for use outdoors.
Construction of SWA Cables:
- Conductor: Plain Stranded Copper (Cu) Conductor of Class 2
- Insulation: XLPE (Cross-Linked Polyethylene) is used as insulation.
- Bedding: PVC (Polyvinyl Chloride) is used for protection.
- Armouring: SWA
- Sheath: PVC
Using SWA for Earthing
- The two major concerns are:
- Reliability and Safety and Health issues.
- Relative conductivity of armoured cable as compared to the cores (which decreases with increasing size of cable)
Benefits of Armoured Cable?
- High-Temperature Resistance: Armoured cables can survive in high temperatures, ensuring reliable performance.
- Enhanced Mechanical Strength: Armoured cables are capable of handling stronger mechanical forces, which also protect against external impact damage, and provide a continuous supply of power.
- Anti-Electromagnetic Interference: Strong anti-electromagnetic interference properties of armoured cables improve power transmission stability and reduce electrical system interruptions.
- Ensures Durability: Armoured cables are constructed in such a way that guarantees longevity and resilience against various environmental factors and stresses. This durability ensures that the cables can maintain their functionality and structural integrity over an extended period, providing reliable performance in electrical installations.
- Flexibility: Whether it's indoor or outdoor applications, armoured cables can handle various power requirements and environmental conditions, offering reliable performance across diverse settings.
- Cost Effective: At the initial level, armoured cables may be more expensive to purchase than standard cables but they prove to be a wise investment over time. Their reduced maintenance needs, extended lifespan, and additional safety features make them a financially efficient choice in the long term.
