MTW Wire

More Information about MTW Wire

Both solid and stranded MTW wire configurations are available. Stranded wire is more flexible and is best for situations that require the wire to be bent or moved, such as in control cabinets. Solid wire is generally used where minimal movement is expected.

This wire also has a UL rating, which signifies its adherence to specific safety and quality standards. This wire's versatility allows it to be used for both internal and external applications—for instance, in cables that encase it for extra protection. It resists oil and the chemicals often found in common machine tool applications, and for this reason, it is a sturdy and industrial-grade solution for many different work settings.

FAQs

Does machine tool wiring and THHN building wire have tinned copper conductors?

Machine tool wiring often has tinned copper conductors, while THHN building wire typically uses bare copper conductors.

What is the construction of appliance wiring material?

Appliance wiring material (AWM) typically consists of stranded or solid copper conductors insulated with thermoplastic or thermoset materials, designed for internal wiring of appliances and equipment.

Industrial Wire Types: Part 1

THHN

Thermoplastic, High Heat resistant, Nylon jacket insulation (THHN) wire is used in conduit or in cable trays due to its rigidity and tough insulation characteristics. THHN can be stranded (several small strands of wire grouped together), allowing for more flexibility and less chance of breakage, or solid (one wire), which is more durable and rigid. THHN wire is suitable for use in dry locations with temperatures that do not exceed 90 degrees Celsius.

XHHW

Cross-linked polyethylene, High Heat-resistant, Water-resistant (XHHW) wire is very similar to THHN. The difference is that XHHW wire is overall a more durable wire that can withstand higher temperatures and is water resistant. XHHW wire can also be found in both stranded and solid wire options.

MTW

Machine Tool Wire (MTW) wire is much more flexible than THHN wire with insulation that is not as durable, making it a poor choice to run through conduit. The flexibility makes it ideal for winding through tight areas, such as wire ducting in an industrial control cabinet. MTW wire is almost exclusively found in stranded wire, which allows for much of the flexibility and reduces the chances of the wire breaking. MTW wire is intended for use in dry locations that do not exceed 90 degrees Celsius or wet locations that do not to exceed 60 degrees Celsius.
