MTW Wire (Machine Tool Wire) is a flexible, high-performance electrical wire designed for industrial machinery, control panels, and factory automation systems. It is known for its oil resistance, durability, and excellent flexibility, making it ideal for environments where equipment is constantly moving, vibrating, or exposed to harsh conditions.
If you’re asking, “What is MTW wire used for?” – the answer is simple: MTW wire is specifically engineered for machine tool wiring, control circuits, motor controllers, and industrial equipment where mechanical stress and heat resistance are critical.
MTW Wire Specifications and Features
Voltage Rating: 600V (UL Type MTW)
Temperature Rating: 90°C (dry), 60°C (wet)
Conductor: Flexible, annealed stranded bare copper for superior flexibility
Insulation: PVC insulation resistant to oil, moisture, heat, and chemicals
Flame Test: Passes VW-1 and FT1 flame resistance
Standards:
UL 1063 (MTW)
CSA AWM I/II A/B
NFPA 79 compliant
RoHS & OSHA approved
Thanks to its multi-strand construction, MTW wire is much easier to bend and route than solid conductors, making it a preferred choice for tight spaces and moving machinery.
What Is MTW Wire Used For?
MTW wire is versatile and is used in:
Control panels and switchgear wiring
Machine tools, robotics, and automated manufacturing lines
Appliance internal wiring and electrical cabinets
Factory automation and conveyor systems
Power and control circuits requiring flexibility and oil resistance
MTW Wire vs THHN Wire: Key Differences
While THHN wire is commonly used for building wiring in conduit, MTW wire is designed specifically for industrial and machine tool environments:
| Feature | MTW Wire | THHN Wire |
|---|---|---|
| Flexibility | Highly flexible (stranded) | Rigid (solid or semi-solid) |
| Oil Resistance | Excellent (industrial-grade) | Limited |
| Main Application | Machine tools, control panels | Building wiring in conduit |
| Temperature/Wet | 90°C dry / 60°C wet | 90°C dry / 75°C wet |
If your application involves moving equipment or tight bends, MTW wire is the better choice.
Available MTW Wire Sizes We Supply
We stock a full range of MTW wire sizes and colors for all industrial applications:

MTW Cable Type vs. TFFN and Other Wires
MTW vs TFFN: MTW is thicker, more durable, and designed for industrial use, while TFFN is lighter and used for fixture wiring.
MTW vs AWM: MTW meets stricter UL and NFPA standards for industrial equipment wiring.
MTW vs THHN: MTW is preferred for moving machinery and vibration-prone environments due to its flexibility.
