THW Cable vs THHN Cable:
THHN cables is 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.
