Product Overview:
The THW Wire Cable is an essential component for modern electrical systems, adhering to the stringent standards set by the National Fire Protection Association. Its copper conductors, known for their excellent electrical conductivity, are insulated with a durable PVC compound that provides resistance to both heat and water. This construction allows the cable to maintain integrity and performance even in challenging environmental conditions, ensuring reliable power and lighting.
This type of conductor is explicitly specified in the National Electrical Code for applications requiring enhanced security and consistent performance.
Applications:
THW Wire Cable is widely used across various sectors for general purpose wiring in power and lighting circuits:
- Industrial Facilities: Ideal for wiring machinery, control panels, and distribution systems in factories and industrial plants, where both dry and wet conditions may be present.
- Commercial Buildings: Suitable for lighting, power outlets, and circuit wiring in offices, retail spaces, hospitals, and educational institutions.
- Residential Homes: Commonly used for interior wiring, connecting electrical outlets, light fixtures, and appliances throughout a home.
- Conduit and Raceway Installations: Designed for easy pulling through conduits and raceways, providing a protected wiring solution.
- Dry and Wet Locations: Its heat and water-resistant properties make it suitable for installation in diverse environments, from dry indoor spaces to damp or wet locations.
Standards:
Our THW Wire Cables are manufactured and tested to meet or exceed the following critical industry standards, ensuring high quality, safety, and performance:
- ASTM B-3: Copper Annealed or Soft Wires.
- ASTM B-8: Copper Stranded Conductors in Concentric Layers, Hard, Semi-hard or Soft.
- UL - 83: Wires and Cables Insulated with Thermoplastic Material.
- NEMA WC-5: Wires and Cables Insulated with Thermoplastic Material (ICEA S-61-402) for Transmission and Distribution of Electric Power.
