What Is MTW Wire?
MTW Wire stands for Machine Tool Wire, a type of cable commonly used for internal wiring of industrial equipment, control panels, and machine tools. It features a flexible, multi-stranded copper conductor with durable MTW insulation that resists oil, moisture, heat, and abrasion.
If you're wondering “what is MTW wire used for?”, the answer is simple: it's designed for wiring industrial machinery, control circuits, and factory automation systems where flexibility and durability are essential.
