Key Features:
- Conductor Material:Typically uses copper for its excellent conductivity and durability. Aluminum is used for larger cables to reduce cost and weight.
- Insulation Layer:The thermoplastic insulation provides excellent heat and moisture resistance, making it suitable for wet and dry environments.
- Applications:THW cables are widely used in residential, commercial, and industrial building wiring, underground installations, power distribution, and control circuits.
THW Cable vs. THHN Cable:
- THHN cableis an improved version of THW, offering higher temperature resistance (up to 90°C in dry environments) and featuring a thinner nylon coating, which improves resistance to oils and chemicals.
THW cables are widely used in electrical installations due to their moisture resistance, heat resistance, and flame-retardant properties, making them ideal for a range of environments and applications.
