What Is an Example of a Low-Voltage Cable? Understanding Types, Uses, and Benefits

If you’ve ever wondered, “What is an example of a low-voltage cable?”, you’re not alone. Low-voltage cables are essential for powering and connecting many of the systems we use every day — from security cameras and Wi-Fi networks to smart home devices and landscape lighting.

In this guide, we’ll explain what low-voltage cables are, where they’re used, and give you real-world examples so you can choose the right one for your next project. Our experienced low voltage wiring professionals in Los Angeles handle installations that meet safety codes and deliver long-term reliability.

What Is a Low-Voltage Cable?

A low-voltage cable is a type of electrical cable designed to carry less than 50 volts (V) of electricity. Unlike standard power wiring that handles 120V or 240V, low-voltage cables are used for communication, control, and signal transmission rather than high-power delivery.

These cables are common in both residential and commercial environments, helping transmit data, video, and low-level electrical signals safely and efficiently.

Common Examples of Low-Voltage Cables

Here are some of the most widely used low-voltage cable types and their typical applications:

  1. CAT5e and CAT6 Ethernet Cables
    • Used for networking and internet connections
    • Support data transfer between routers, computers, and IP cameras
    • Essential for CCTV and structured cabling installations
  2. Coaxial Cable (RG6 or RG59)
    • Used for cable television, satellite connections, and security camera systems
    • Provides reliable signal transmission over longer distances
  3. Speaker Wire
    • Transmits audio signals from amplifiers to speakers
    • Common in home theaters, sound systems, and public address installations
  4. Thermostat Wire
    • Powers and connects thermostats to HVAC systems
    • Typically rated at 24V for heating and cooling controls
  5. Security System Cable (18/2, 22/4, etc.)
    • Used for alarm systems, motion sensors, and keypads
    • Available in different conductor counts for various devices
  6. Landscape Lighting Cable
    • Designed for outdoor low-voltage lighting systems (usually 12V)
    • Weather-resistant and safe for buried applications
  7. Fiber Optic Cable
    • Carries data as light instead of electricity
    • Used for high-speed internet, network backbones, and telecommunications

Each of these cables serves a specific purpose, but they all share the same characteristic: safe, low-voltage power or data transmission.

Why Use Low-Voltage Cables?

Low-voltage cables offer several advantages over traditional high-voltage wiring:

  • Safety: Lower risk of electrical shock or fire
  • Energy Efficiency: Designed for smaller power loads, saving electricity
  • Flexibility: Easier to install in tight or sensitive spaces
  • Compatibility: Works with smart home and modern communication systems
  • Cost-Effective: Cheaper materials and lower installation costs

Whether you’re wiring a new security system, upgrading your Wi-Fi network, or setting up landscape lighting, low-voltage cables help you do it safely and efficiently. There are various kinds of low voltage cables used for different purposes. You can explore the different types of low voltage cabling to understand their specific applications.

Where Low-Voltage Cables Are Commonly Used

Low-voltage wiring is everywhere in modern California homes and businesses. Some examples include:

  • Security systems: Cameras, motion detectors, alarms
  • Home automation: Smart lighting, doorbells, and speakers
  • Networking: Wi-Fi access points, routers, and Ethernet ports
  • Entertainment systems: Audio and video distribution
  • Commercial properties: Access control and building management systems

If your goal is reliable communication and control without high power needs, low-voltage cabling is the best solution.

Choosing the Right Low-Voltage Cable

When selecting a low-voltage cable, consider the following factors:

  • Application: Determine if you need it for data, video, audio, or power.
  • Distance: Longer runs may require thicker wire or shielded cable.
  • Environment: Use plenum-rated or outdoor-rated cables as needed.
  • Code compliance: Ensure cables meet California low-voltage wiring standards if you’re installing within the state.

Hiring a licensed low-voltage contractor ensures that all cables are installed correctly, safely, and in line with local regulations.
