18 2 low voltage cable refers to a two-conductor wire (2) with 18 AWG (American Wire Gauge) thickness, designed specifically for low voltage electrical systems (typically under 50 volts). It is commonly used in:
Security systems (alarms, sensors)
Landscape lighting
Thermostats and HVAC controls
Intercoms and doorbells
Access control systems
The “18” refers to the wire’s gauge, meaning it’s thin yet sufficient for low current applications, while “2” represents the number of conductors inside the cable. It is often available in solid or stranded copper variants, depending on flexibility and conductivity needs.
Whether for residential, commercial, or light industrial use, the 18 2 low voltage cable provides an ideal wiring solution for multiple environments. Here are some of its most common applications:
This cable is a standard in the security industry for wiring motion detectors, contact sensors, glass break sensors, and control panels. Its dual conductors make it simple to install while providing enough power and signal strength.
In heating and air conditioning systems, 18/2 low voltage cables provide efficient and reliable transmission for thermostat connections to HVAC units, enabling temperature regulation and energy efficiency.
Used for garden lighting and low-voltage path lights, this cable can handle long-distance runs when connected to a transformer, offering durability in outdoor environments with proper jacketing.
It’s also an excellent choice for doorbell wiring or simple two-way communication systems.
Popular in home automation and smart lighting systems, these cables are widely used for low-voltage LED lighting installations.

Yes, it’s a popular option for landscape and path lighting systems, especially when distances are not excessive. For longer runs, consider voltage drop calculations.
Solid wire is best for stationary installations, while stranded wire is more flexible and better suited for areas that require bending or movement.
Our direct burial-rated versions are waterproof and UV-resistant, ideal for outdoor applications.
Color choice depends on code requirements or personal preferences—white and black are standard, but we also offer custom colors on request.
At Honglincabe, we understand that the right cable is critical to the performance of your low voltage systems. Whether you’re a DIY homeowner or a professional installer, our 18 2 low voltage cable offers unbeatable reliability, competitive pricing, and tailored service.
