Top 5 Types of Electrical Wires You Need to Know
Think of the electrical systems as your building's nervous system. Be it a residential society, a pharmaceutical business or a factory, wires keep the establishment up and running. Choosing the right type of wire ensures safety, efficiency, and long-term reliability. This blog highlights the different types of Electrical wires that you should know about.
1. THHN (Thermoplastic High Heat-resistant Nylon-coated) Wire
Thermoplastic Heat-resistant Nylon-coated wires are mainly used in commercial and industrial applications. THHN wires are heat-resistant and are ideal for conduits due to their high temperature ratings and abrasion resistance properties provided by an extra layer of Nylon.
2. Braided Cable (AC)
The first armored cables came into being during the early 1900s and evolved as Copper Armoured Cables for improved safety, efficiency and durability in electrical installations. These cables have a multi-layered design with conductor, insulation, filler, armouring and sheath. Copper is used as a conductor material, ensuring excellent conductivity, with the armouring made of steel, protecting against damage, and the insulation made of materials like XLPE. Copper armoured cables are used where cables are exposed to harsh environments where protection from mechanical damage and electrical conductance is required. They find uses in power distribution, and underground and outdoor installation projects.
3. Coaxial Cable
Coaxial cables, also known as coax cables, are specially designed for long-distance transmission without signal loss while maintaining precision and integrity. These electrical cables have three layers – a central conductor, usually made of copper or aluminium, enclosed with a dielectric insulator, purposed to prevent signal leakage. The third layer is the protective sheet to protect against electromagnetic interference, covered with a durable outer jacket. Due to their construction, coax cables are widely used to reliably transfer data signals with minimal signal loss over long distances.
4. Single Core Flexible Cable
Single Core Flexible Cable come with tight bending radii and can cope with stressful environments. As the name suggests, it has a single metal wire inside it, usually copper or aluminium, with insulation of rubber or PVC wrapped around it. They can cater to industrial and civil uses over long distances.
5. NM (Non-Metallic) Cable
NM Cables, also known as Romex, are a popular choice for residential wiring due to features such as cost-effectiveness and ease of installation. These cables are usually used in interior walls and ceilings.
Conclusion
Understanding the key types of electrical wires helps streamline project planning and ensures safety compliance. Whether you're sourcing for a new build or retrofitting an existing structure, matching the wire type to its application is crucial. Need help selecting the right wires?
