In modern industrial applications, choosing the right wire directly impacts equipment safety, performance, and service life. Two commonly compared options are MTW Wire (Machine Tool Wire) and TEW Wire (Thermoplastic Equipment Wire).
For engineers, contractors, and procurement managers, the question often arises: MTW vs TEW - which is the better choice for industrial use?
This article provides a detailed breakdown of MTW and TEW wires, covering their definitions, standards, key differences, applications, and selection criteria. Finally, we will explain why MTW Wire (Type MTW Cable) is typically the preferred option for industrial environments.
What Is MTW Wire?
MTW Wire (Machine Tool Wire) is a specialized conductor widely used in machine tools, control panels, and industrial automation systems.
Insulation: PVC insulation with strong oil and moisture resistance.
Applications: Suitable for control panels, wet environments, industrial cabinets, and MTW hook up wire inside equipment.
Flexibility: Designed with excellent flexibility for routing through tight spaces.
Standards: Complies with UL 1063 Type MTW and CSA standards, ensuring broad acceptance across North America.
Typical Applications: Control wiring in machine tools, industrial automation, panel wiring, outdoor enclosures.

What Is TEW Wire?
TEW Wire (Thermoplastic Equipment Wire) is commonly used in appliances and equipment where compact, lightweight wiring is needed.
Insulation: PVC-based, but with thinner insulation compared to MTW.
Applications: Best for dry environments such as inside appliances, instruments, and light equipment.
Flexibility: Thinner insulation makes TEW wire more flexible than MTW.
Standards: Meets UL 1015/1028/1283 Type TEW requirements.
Typical Applications: Appliances, instrument panels, light equipment, indoor wiring.
MTW vs TEW Wire: Standards and Technical Comparison
To clearly understand the differences, see the comparison table below:
| Feature | MTW Wire (Type MTW Wire) | TEW Wire (TEW Cable) |
|---|---|---|
| Full Name | Machine Tool Wire | Thermoplastic Equipment Wire |
| Standards | UL 1063, CSA AWM I/II A/B | UL 1015/1028/1283 |
| Insulation Thickness | Thicker, oil & moisture resistant | Thinner, lightweight |
| Flexibility | Good flexibility, durable | Higher flexibility, less rugged |
| Environmental Suitability | Wet, oily, outdoor & industrial panels | Dry, indoor environments |
| Typical Use Cases | Machine tools, control cabinets, automation, outdoor enclosures | Appliances, instruments, small equipment |
| Key Advantage | Rugged, durable, industrial-grade | Lightweight, excellent flexibility |
How to Choose the Right Wire for Industrial Applications
When selecting industrial wire, the following criteria should be considered:
Installation Environment
Industrial cabinets, wet locations, outdoor enclosures → Choose MTW Wire (Type MTW Cable).
Dry, indoor equipment → TEW Wire is sufficient.
Flexibility Needs
High bend radius applications (e.g., robotic arms, compact equipment) → TEW Wire.
Durability in harsh environments → MTW Wire.
Compliance & Standards
For North American markets, MTW Wire is more commonly required in industrial projects since it meets UL and CSA industrial standards.
MTW vs TEW: Which Is Better for Industrial Use?
For industrial applications such as machine tools, automation systems, and control cabinets, MTW Wire (Type MTW Cable) is the superior choice.
Why MTW?
Stronger insulation, higher resistance to oil and moisture.
Certified as UL Type MTW Wire for wet, oily, and outdoor environments.
Meets CSA standards for industrial wiring.
TEW Wire, while excellent for flexibility, is best suited for appliances and indoor equipment wiring, not heavy-duty industrial systems.
MTW Wire (Type MTW Wire) is more suitable for industrial use
When comparing MTW vs TEW Wire, the choice is clear:
MTW Wire (Type MTW Cable) is the ideal option for industrial use, offering superior durability, oil and moisture resistance, and UL certification for wet environments.
TEW Wire is better suited for appliances and dry indoor equipment wiring where flexibility is more important than ruggedness.
