What Are Single Core Cables?

 

Single core cables come with only one electrical conductor shielded with an insulating layer. This means it will be either a single copper or aluminum conductor.

In comparison with multicore cables, cables with one conductor are more efficient. They can withstand harsh weather conditions, making them ideal for high voltage applications.

Let us explore their benefits and applications in this blog.

Benefits of Single Core Cables

The following are some benefits of single core cables:

Single conductor design: Since it is just one conductor, single core cables have the simplest design and construction. They create one path for the current to travel. These cables provide smooth connections and terminations, ensuring optimal performance of electrical systems.

High current carrying capacity: Cables with just one conductive core can be arranged with better spacing from other single core cables. This extra spacing allows for better heat dissipation and reduces risk of overheating. As a result, these cables can safely carry higher current for the same cross sectional area.

Low voltage drop: Single core cables experience lower electrical resistance. This significantly reduces the voltage drops along the circuit, especially during long distance power transmissions.

Superior durability: Single core cables' solid structure make them durable. Also, the copper or aluminum conductive material offers exceptional corrosion-resistance properties, ensuring the cables stand tall in extreme temperatures and environmental conditions. Basically, they can last as long as possible for one permanent installation.

Reduced interference: Their simple design ensures the least electromagnetic interference. Therefore, single core cables are ideal for high voltage applications where signal integrity is the main priority.

Applications of Single Core Cables

Here are a few common applications of single core cables:

Power grids: In power grids, single core cables smoothly deliver electrical energy to substations, residential and commercial areas. In residential houses, single core cables are used in domestic wiring systems and appliances.

Telecommunications networks: Telecommunication networks spread over long distances through towers to transmit signals and data. These networks connect remote areas with mainstream cities. To power these towers and ensure smoother operations, the cable network is laid using single core cables.

Automobiles: These cables are also used in vehicles to support control systems and electrical functions.

Industrial automation systems: They are also utilized in automation systems and control panels to facilitate smooth and stable industrial operations.

Construction projects: In construction projects as well, these cables are used on a larger scale to transfer high currents safely.
