The main difference between THWN wire and MTW wire lies in their application areas and characteristics.
THWN cable is a thermoplastic polyvinyl chloride insulated wire with excellent heat resistance, capable of long-term use at temperatures up to 90 ℃ and withstanding higher temperatures in a short period of time. Its insulation layer is made of polyvinyl chloride (PVC), and the sheath is made of flame-retardant nylon material, which has high mechanical strength and good chemical stability. THWN cable are commonly used in general industrial power distribution systems, capable of withstanding high temperatures and suitable for use in high-temperature environments.
MTW cable, also known as mechanical tool wire, is a flexible and bendable twisted jumper wire mainly used for internal electrical circuits, such as refrigeration equipment, automatic washing machines, air conditioning equipment, mechanical tool control circuit systems, and various construction machinery control circuit systems. Its insulation material is usually oil resistant polyvinyl chloride, which can be used in oily environments. Colleague MTW cable has high flexibility and bending resistance, making it suitable for use in environments with frequent movement and bending.
In summary, THWN cable are mainly used in general industrial power distribution systems, emphasizing heat resistance performance; MTW cable are mainly used for internal electrical circuits, emphasizing oil resistance, flexibility, and easy bending performance.
