Ampacity can change based on ambient temperature, installation condition (in conduit, free air), and derating factors.
Insulation: Mostly Nylon-jacketed PVC for THHN/THWN-2; other types like XHHW use Cross-linked Polyethylene (XLPE).
Core Type: Smaller sizes are often solid for easier terminations; larger sizes are stranded for flexibility.
Number of Conductors: Single conductor is standard; multi-conductor assemblies exist (e.g., MC cable, tray cable).
Power Distribution, distributing electricity inside buildings (offices, homes, factories) from a main panel to outlets, lights, equipment.
Lighting Systems, especially in commercial buildings, warehouses, stadiums, street lights — LV cables connect to lighting fixtures.
Control Systems, sed in machinery or building automation to send control signals (like starting a motor or opening a valve).
Data and Communication, some low voltage cables (like Cat5, Cat6) are specialized for networking, alarms, intercoms, or CCTV systems.
Fire Alarm Systems, fire-rated LV cables are used to connect fire detection and alarm devices.
Audio-Visual Installations Speakers, projectors, and home theater wiring often use low voltage cabling.
Renewable Energy Systems, solar panels, small wind turbines — low voltage cabling connects DC outputs to inverters and batteries.
Security Systems Access control, security cameras, and motion detectors are wired with LV cables.
Apply cable base on its insulation property
Always de-energize the system before working on cables
Proper PPE duing operation
| Voltage Rating (Up to 1kV) | Safe for residential, commercial, and light industrial power and control applications — prevents electrical hazards at low voltages. |
| Flexibility | Easy to install around bends, ceilings, walls, and machinery — saves time and labor costs. |
| Shielding Options | Protects signals from electromagnetic interference (EMI), critical for clean data, communication, and control signals. |
| Fire Resistance (Rated Types) | Ensures cables maintain circuit integrity during fire — essential for safety systems like alarms and emergency lighting. |
| Durability (Armored, Outdoor Rated) | Withstands physical damage, weather, and UV exposure — increases system lifespan in harsh environments. |
| Color Coding and Labeling | Easier identification during installation, troubleshooting, or future upgrades — reduces errors and downtime. |
| Low Smoke Zero Halogen (LSZH) Options | Produces minimal toxic gases when burning — crucial for enclosed spaces like tunnels, ships, or crowded buildings. |
| Cost Efficiency | Lower material and installation costs compared to high voltage systems — ideal for widespread applications. |
