Cables are a basic building block of modern electronic design, serving to organize the various wires that transport electricity and signals between devices and circuits. With everything from residential buildings and automobiles to manufacturing facilities and aircraft featuring various tables of cables to support the functionality of electronics, it is important to have the knowledge necessary to choose the right solution for a particular application.
In this guide, we will explore the main types of electrical cables that are available on the market, highlighting their key characteristics, primary uses, and benefits.
An Overview of Popular Electrical Cable Types
There are dozens of cable varieties available in the market today, each being uniquely suited for specific needs. Below, we will provide an introduction to some of the most frequently used types and how they function in real-world settings.
Underground Feeder (UF) Cables
Underground Feeder cables are specifically designed for underground use and outdoor environments, where each wire is individually insulated with thermoplastic and encased in a moisture-resistant outer layer. These cables are often found in:
Their flexibility and water-resistant properties generally make them ideal for installations directly in soil or concrete, driving their use in such settings.
Non-Metallic Sheathed (NM) Cables
Commonly found in residential construction, NM cables include two or more conductors covered in a plastic sheath and come in types like NM-B or NM-C. There are also variants like the TECK cable, which includes extra thermoplastic insulation for added durability. Typical uses for these cables include:
They are also easy to install, are cost-effective, and compliant with residential codes, making them popular.
Metallic Sheathed (BX) Cables
For applications requiring more protection, metallic sheathed or armored cables can provide superior durability. These cables feature three copper wires (live, neutral, and ground), which are insulated with cross-linked polyethylene and wrapped in PVC bedding. These cables are frequently used in:
Multi-Conductor Cables
Multi-conductor cables feature multiple individually insulated wires within a single outer sheath. These cables are commonly used in both residential and commercial settings due to their flexibility and organization, with common applications including:
Coaxial Cables
Known for their reliable signal transmission abilities, coaxial cables consist of a central conductor, an insulating layer, a shielding metal sleeve, and a protective jacket. Because of their construction, they reduce interference and are suited for:
Twin Lead Cables
Twin lead cables are basic, flat cables that contain two parallel conductors. These are mainly used for signal transfer between antennas and receivers, with common scenarios of use including:
They are generally considered to be an affordable option for simple signal transmission with minimal interference concerns.
Unshielded Twisted Pair (UTP) Cables
UTP cables are known for being cost-efficient and lightweight, their design consisting of two wires that are twisted together to reduce crosstalk. Unlike other designs, these cables lack shielding, making them ideal for short-range data communication in low-interference environments. Typical applications they serve include:
How to Choose the Right Cable For Your Needs
When selecting between electrical cable types, you should take the following into account:
For safety and efficiency, always consult a certified electrician if you are unsure.
