Different Types of Electrical Cables and Wires Used In Construction Sites

Electrical wires and cables are like veins to a building. It’s a common fact considering whether it is a commercial or an individual building. In the construction process, electrical work plays a major part in the completion of a project. Moreover, electrical work is the most sensitive process as there are a lot of precautions and safety measures involved in it.

Especially, when it is involved in very large projects there will be hundreds and thousands of electricians working on it. Where the safety precautions and protection gears will be employed in abundance. An error or a mistake would never be in acceptance in the electrical work, as the rework may cost more time and money.

The Electrical Wires and Cables

So just like the designing phase, the electrical work also will be on a pre-design basis to connect the electrical materials and connections perfectly. So when lot preparations and precise calculations in electrical work, the electrical cables and wires must be of top-notch quality to perform the designed work.

Based on the demands and types of connections in using the electrical wires and cables are classified. However, the requirement of the electrical cables and wires differs based on commercial and individual buildings. To help the contractors and budding electricians, we are here to classify the best cables and wires available in the market.

Coaxial Cable

Coax, also known as coaxial cable. It is a type of electrical cable build of four layers in a coaxial pattern (having a common axis or centre). A coaxial cable’s central component is a conductor in cover with a metallic shield and in protection with an insulating plastic layer. On top, the fourth layer of plastic insulation is in protection.

High-frequency signals are transmitted using coaxial cables. As a result, the metallic shield is in use to shield against noise interference. It’s commonly in use for cable television signal distribution and signal transmission between antennas, transmitters, and receivers.

Cables with Armor

Armoured cables are shielded or covered with various types of PVC or metal shields. Armour is to defend shield cables from high-pressure washing, extreme heat or cold, and corrosion. 

These electrical cables are primarily in use for industrial applications such as heavy machinery and computer setups. Moreover, its widely in use for commercial building purposes.

Cables with a Non-Metallic Sheath

Non-Metallic Sheathed Cables, also known as Romex or NM cables, are flexible electric cables. Widely used in our residential homes. The basic model of these cables comes with two insulated wires, one of which is a ground copper wire. It is in use to provide a safe flow of electrical current in emergencies.

This was a basic overview of the wires and cables that are in use for our homes and businesses places. To transmit data, electricity, and other types of signals. Use Primecab wires and cables made of high-quality PVC and refined metals for the best electricity and data transmission.

Communication Cables

Communication cables denote the phone cables and data cables. Telephone and data wiring are low-voltage wires that are in use to connect “landline” telephones and internet connections. Telephone cables can have four to eight wires. The most common type of household data wiring is Category 5 (Cat 5) cable, which has eight wires wrapped together in four pairs. As a result, it has a higher capacity and quality than standard phone wire. Therefore, it can be in use for both phone and data transmission.

Although data wiring does carry some voltage, anything less than 30 volts generally is in a safer position.

However, there is always a risk that data wiring will come into contact with household wiring. So proceed with caution and avoid touching bare wires.

Fiber Optic Cables

Fiber optic cable, also known as optical fibre cable. It is a type of communication cable build with flexible, transparent glass fibres known as optical fibres. That can transmit data in the form of light. The thickness of the fibre is comparable to that of human hair, and each fibre is insulation with plastic. Another external protection layer shields the fibres from interference.

The fibre optic cable is split into two types:

Mono-mode and Single-Mode Fibre Optic Cable

Low Voltage Wires

Low-voltage wiring is in use for circuits typically requiring 50 volts or less. Several common types are landscape lighting wire, sprinkler system connections, bell wire (for doorbells), speaker system wires, and thermostat wires. Wire sizes range from about 22 gauge to 12 gauge. Low-voltage wires typically are insulated and may be contained in cable sheathing or combined in twisted pairs, similar to lamp cord wire. It should only be used for low-voltage applications. These are usually very small wires that differ greatly from standard circuit wiring.

Ribbon Cables

The ribbon cable is build from multiple small grade insulation wires parallel to each other in a flat shape that resembles a piece of ribbon, hence the name. They are adaptable and can work with very low voltages.

Submersible Cable 

This type of electrical cable, as the name implies, is in use for wet environments or when in liquid submersion. To meet the challenges of the installation environment, the insulation in use for such cables are very rug, abrasion-resistant, and extremely durable and reliable. For in use as direct buried cables.

Based on their usage, available in single and multiple conductor designs with flat or round structures.

Colour Codes representation in the conductors distinguishes between phase and earth connections. As well as it controls wires that run along the power conductors.


The electrical cables and wires quality determines the quality of the electrical work in a building. So make sure you fetch the quality your construction work deserves. We are always here to assist you in choosing your Electrical materials.
