Allied Encyclopedia: MTW/TEW Wire

What is MTW/TEW Wire?

MTW/TEW wire is UL rated Flexible Machine Tool Wire. MTW stands for Machine Tool Wire and TEW stands for Thermoplastic Equipment Wire. The UL ratings are UL 1028, UL 1283, UL 1284 and UL 1015.
MTW/TEW cable is used in machine tool applications. These include switchboards, appliances, electronic circuits, control cabinets and the wiring of machine tools. MTW wire passes the VW-1 flame test and is also moisture resistant. This article will examine two types of MTW/TEW wire which is available with either a tinned copper and bare copper conductor.

TEW / MTW Wire Construction
TEW/MTW wire is available with conductors that are tinned copper hook up wire or stranded bare copper hook up wire. It is used primarily in the wiring of machine tools and control cabinets, electronic circuits and switchboards. This wire is UL 1028, UL 1283, UL 1284 and UL 1015 rated. This wire features PVC (polyvinylchloride) insulation which makes it resistant to heat, moisture and oil. TEW cable is available with a variety of wall thicknesses, weights and sizes.

UL Ratings

MTW and TEW have dual UL ratings. This simply means that the wire meets more than one industry standard. The most common UL ratings for these wires are UL 1028, UL 1283, UL 1284 and UL 1015.

Wire Size Conductor Temperature Rating Voltage Rating Min. Average Thickness
UL 1028 22 AWG-6 AWG Solid or stranded

Tinned or bare copper

105°C 600V 22-8 AWG/ 45 mils

7-6 AWG/ 60 mils

UL 1283 8 AWG-1000 MCM Solid or stranded

Tinned or bare copper

105°C 600V 60 mils
UL 1284 8 AWG-2 AWG Solid or stranded

Tinned or bare copper

105°C 300V 80 mils
UL 1015 30 AWG – 2000 MCM Solid or Stranded 105°C 600 V 30-9 AWG/ 30 mils

8-7 AWG/ 45 mils

6-2 AWG/ 60 mils

1-4/0 AWG/ 80 mils

250-500 MCM/ 95 mils

550-1000 MCM/ 110 mils

110-2000 MCM/ 125 mils

There are several characteristics of the wire that influence the UL rating. With these specific styles, a wire that is 8 AWG could possibly be approved as UL 1028, UL 1283, or UL 1284 ratings. However, a wire that is 2 AWG could only have UL 1283 or UL 1284 ratings. Another characteristic that can determine which UL ratings a wire could be approved as is the minimum average insulation thickness. A wire that is 6 AWG would overlap UL 1028 (60 mils), UL 1283 (60 mils), and UL 1015 (60 mils), and could potentially be dual rated as all three styles. However a wire that is 4 AWG would not be able have both ratings because the insulation thicknesses are 60 mils vs 80 mils.These thicknesses are not the same for both styles.  MTW/TEW wire also can have other dual ratings such as SAE 1127, Type SGT rating which are controlled by other organizations such as NEMA or SAE. A UL 1284 wire with a bare copper conductor in sizes 6 AWG to 4/0 can be dual rated as SAE 1127, type SGT, since the requirements of both styles overlap. For more information on dual ratings, check out our Allied Encyclopedia article on this topic.

While the above paragraph gives a full overview of how dual ratings can work, within the wire and cable industry, there are some very common dual ratings.  The chart below covers the most common dual ratings according to industry standards for MTW wire.

Main UL Rating Size
UL 1015 10 AWG and smaller
UL 1028 8 AWG
UL 1283 6-2 AWG
UL 1284 1 AWG and larger
BC5W2 Tinned: 6 AWG -4/0

Bare: 6 AWG – 750 MCM

There is also the BC5W2 rating for wires sized 6 AWG- 4/0 tinned and 6 AWG – 750 MCM bare.

LMR-100 vs RG316 | Product Knockout

“Our Product Knock-out series is a match-up between two similar products. In boxing terms, think same weight class, same caliber, and same level of experience and amount of exposure. The purpose of these posts are for you to see a side-by-side view of two similar products, and to be able to understand which one will be crowned champ for your specific purposes. Take your seats and prepare for battle, because the gloves are coming out.”

LMR 100 and RG316 have some similarities and some differences. This product knockout post is going to examine the characteristics of LMR-100 vs RG316 cable. The two will then be compared and contrasted. Let’s take a closer look at these two cables.

What is LMR 100 Cable?

LMR 100 is a flexible, low loss, communication cable. This cable is ideal in applications such as short antenna feeder runs and jumper assemblies that are mostly in wireless communication systems. LMR 100 can also be used in applications that require easily routed, low-loss cable such as WLL, GPS, WLAN, etc. This cable features a flexible outer conductor which allows the tightest bend radius of any cable that is similar is size and performance. It also boasts the lowest loss of any flexible cable. LMR cable may be used as a drop in replacement for RG 316 or RG 174 cable.

What is RG 316 Cable?

RG 316 is a coax, military rated, communication cable. This cable can be used in applications such as military equipment, direct burial, transmission of radio frequency signals, and telecommunications. It can also be used for high frequency interconnections between PCB in telecommunications equipment. RG-316 is also an ideal choice for applications that require high performance and stability in high temperature environments or in applications that have minimal installation space.  RG316 coax is also a low loss cable. Due to the large size of its conductor, the attenuation of RG316 is lower than other options in this category. This cable is also in accordance with MIL-DTL-17 specifications. This part is M17/113-RG316.

LMR 100 vs RG316 Cable

LMR 100 cable and RG 316 cable have some similarities and some differences. The cables are also both coaxial cables used in communications/telecommunications applications. They both have an impedance of 50 ohms. Below is a chart that compares the similarity of low loss/attenuation characteristics. As the chart shows, the low loss is comparable at a variety of different frequencies, but the LMR-100 cable performs slightly better. Both of these cables have low loss, or attenuation characteristics.

LMR-100 Loss (Attenuation dB/100ft) RG316 Loss (Attenuation dB/100ft)
30 MHz 3.9 4.3
50 MHz 5.1 5.6
1500 MHz 30.1 32

As the chart shows below these cables are constructed differently. LMR-100 has a conductor that is solid bare copper clad steel, where RG316 has a stranded silver covered copper clad steel conductor. RG-316 having a stranded conductor, makes it more flexible than the solid conductor of LMR-100. Another major difference one can see from the chart is that RG316 has a higher temperature rating. The higher temperature rating is made possible by the jacket type of RG-316 coax which is Fluorinated Ethylene Copper (FEP). This allows the cable to be used in specific applications that require that higher temperature environment in comparison to the LMR-100.

LMR-100 vs RG316

LMR-100 vs RG316 Specs for Construction
LMR-100 RG316
Conductor Type Solid Bare Copper Clad Steel Stranded Silver Covered Copper Clad Steel
Dielectric Material Solid Polyethylene (PE) Solid Polytetrafluoroethylene (PTFE)
Outer Conductor Aluminum Tape Silver Covered Copper Braid
Jacket PVC or FRPE Fluorinated Ethylene Copper (FEP)
Temperature -40°C to +85°C -55°C to + 200°C

Although LMR 100 can be used as a drop in replacement for RG 316, it does not have a mil-spec call out. This is another major difference when we compare LMR 100 vs RG316. RG 316 coax has a military call out, M17/113-RG316.

Winner by unanimous vote? Instead, it seems as if the match has ended in a technical decision.
In this case it looks like our crowned champ depends on your specific application use.

Clarkson University’s Zero-Emission Snowmobile SAE Team Update

 Last month you read how Allied Wire & Cable helped the Clarkson University Zero Emission Snowmobile SAE Team prepare for the SAE Clean Snowmobile Challenge. The challenge took place at Michigan Technical Institute in Houghton, MI.

Allied’s contribution has greatly helped the Clarkson Electric Knights reach their goal of placing in the top three at the 2017 SAE Clean Snowmobile Challenge. We are happy to report that The Electric Knights placed 2nd overall.  This ranking has been their personal best since 2010.

The Zero Emission category at the Clean Snowmobile Challenge consisted of twelve events that took place from March 6th – 11th 2017. The events were listed as follows: Design Paper, Static Display, MSRP Report, Subjective Handling, Range, Oral Presentation, Noise, Draw Bar Pull, Cold Start, Vehicle Weight, Objective Handling, and Acceleration Under Load. At this year’s competition the Electric Knights took 1st place in both the cold start event and draw bar pull. They had a max pull of 627 lbs and a vehicle weight of 858 lbs. The team also finished with the fastest time (55.16 seconds) in the objective handling event. The acceleration under load event requires one snowmobile to pull another snowmobile 400 feet as quick as possible.  The Electric Knight’s sled finished in 1.29 seconds right after the 21.27 seconds of the winner.

Unfortunately, The Electric Knights ran into some complications with their battery pack leaving them unable to finish the noise and range events. However, this was the first year The Electric – Knight competed in all events since 2011.

Allied could not be more proud of the accomplishment from Clarkson’s Electric Knights. Job well done to everyone involved!

Allied Donates to Clarkson University’s Zero-Emission Snowmobile SAE Team

snowmobile-collage

This March, Allied Wire & Cable will play a part in the SAE Clean Snowmobile Challenge at Michigan Technical Institute. Allied made a donation to help the Clarkson University Zero-Emission Snowmobile SAE Team located in Potsdam, NY. The competition is conducted through the Society of Automotive Engineers. SAE encourages those involved to be innovative, including using time for networking and learning to be a sound engineer through the design and build process.

 

The Clarkson University Zero-Emission Snowmobile SAE team is a group of dedicated, undergraduate engineering students participating in an international collegiate design competition that challenges students to develop and build an electric snowmobile. The teams says this will be done by replacing an internal combustion engine with an electric motor on a stock snowmobile chassis. During the academic year, the team will be applying the principles that they have learned in the classroom and putting them towards a real world application to build a competitive snowmobile in Michigan.

 

Allied Wire & Cable donated hundreds of feet of wire to the Clarkson team for their snowmobile. Some of the wires donated  to the Clarkson team were UL 1007 Hook Up Wire of 07-22-7T, 07-16-26T and 1569-12-65T. The wire will be used throughout the entire snowmobile in every electrical aspect. For example, the areas of focus will be the controls and operation of the tractive system, the safety circuits and other components that are incorporated to ensure the vehicle is operating under safe and normal conditions. The systems also include the isolation monitoring device, battery management system, accelerator lever position sensor and brake pedal plausibility check systems. Allied’s wire products will also play a role from the low voltage control circuit to the high voltage battery pack monitoring and cell balancing.

Check back with us in March to see how the Clarkson team did in their competition!
