Types of Electrical Cables or Types of Electrical Wires

There are various types of Electrical Cables which are listed below –

Armored Cable

An electrical cable with an extra layer of protection built in is called an armored cable. Usually made of steel or aluminum, this protective layer is coiled around the inner conductors. This metal armor gives the cable more strength and endurance, increasing its resistance to impact and crushing as well as providing further defense against moisture, chemicals, and other environmental elements. In installations where additional protection is required, such as in outdoor or industrial environments, where the cable may be exposed to harsh circumstances or where there is a risk of mechanical damage, armored cables are frequently utilized.

Advantages of Armored Cable

1. It offers resistance against moistures, chemicals and other environmental factors.
2. These cable helps to prevent electrical faults.
3. Protected against mechanical damage.

Applications of Armored Cable

1. Used in Industrial Installation
2. Outdoor installation
3. Also in commercial and residential areas.

Flexible Cable

An electrical cable that may be easily bent or flexed without harming it or impairing its functionality is called a flexible cable. The materials and designs used in the construction of these cables allow them to be repeatedly bent, twisted, or moved without breaking. Applications including machinery, robotics, electronics, and portable gadgets that need for constant bending or movement frequently use flexible wires. They’re perfect for situations where rigidity or stiffness in wiring could cause problems because they’re designed to keep their electrical integrity even when bent to varying degrees.

Advantages of Flexible Cable

1. They can easily flex without any damage.
2. More durable.
3. Simple to install at anywhere.

Applications of Flexible Cable

1. Used in Machinary and Robotics
2. Residential Areas
3. In Electronics Items also.

PVC Wires

Electrical wires with PVC (polyvinyl chloride) insulation are referred to as PVC wires. PVC is a kind of plastic that is renowned for its strength, pliability, and ability to withstand chemicals and moisture. PVC-insulated wires are frequently used in electrical wiring for residences, structures, and other uses. Their price, simplicity of installation, and fire resistance make them popular. The conductive core of the wire is shielded from electrical risks and the safe and effective transfer of power is ensured by the PVC insulation.

Advantages of PVC Wires

1. Its insulation offers robust protection.
2. Provides a degree of fire retardance.
3. Simple to work when we installing it.

Applications of PVC Wires

1. Used in Home and Apartments.
2. Used in Commercial Buildings.
3. Also used in Electrical appliances.

CTS Wire

Copper-Clad Steel wire is referred to as CTS wire. This particular kind of wire has a copper layer covering a steel core. This blend provides the conductivity of copper with the strength of steel. CTS wire is frequently utilized in applications like telecommunications, electrical grounding systems, or specific kinds of antennas where both strength and electrical conductivity are necessary.

Advantages of CTS Wire

1. Strength is high.
2. It offers good electrical conductivity.
3. Resistant to corrosion due to copper layer.

Applications of CTS Wire

1. Used in Telecommunication systems
2. Used in Antennas
3. Also used in electrical installations.

LC Wire

Lead-Covered wire is referred to as LC wire. It describes a kind of wire or electrical cable that has a layer of lead covering it. Improved defence against environmental elements such as moisture, corrosion, and certain chemical exposures is offered by this lead covering. LC wires are frequently utilised in particular situations when protection against these factors is essential, as in severe settings or subterranean installations.

Advantages of LC Wire

1. It offers exceptional protection.
2. It also offers high durability.
3. Suitable for various kind of applications.

Applications of LC Wire

1. Used in Underground applications.
2. Used in Chemical Environments.
3. Used in harsh conditions also.

FR Wire

Fire Retardant wire is referred to as FR wire. It’s a particular kind of electrical wire made of components intended to prevent or delay the spread of fire. In the event of a fire, the risk of the fire spreading along the FR wire is decreased because it is built with fire-resistant insulation and coatings. These cables are frequently utilized in situations where preventing fires is crucial, such as in residences, buildings, and other locations where fire risks must be kept to a minimum.

Advantages of FR Wire

1. Specifically designed to resist the spread of fire.
2. Slows down or inhibits fire propagation along the wire.
3. Maintains electrical integrity even under fire exposure.

Applications of FR Wire

1. Used in emergency lighting.
2. Fire Alarms.
3. Installed in offices, retail stores.
