Flammability Test on CAT6 Gel Filled Direct Burial Ethernet Cable

By John Smith

TrueCable's Don recently conducted an interesting test on their new CAT6 Gel Filled Direct Burial Ethernet Cable. In this article, we'll recap Don's flammability test and see what the results showed about whether this cable type is flammable or not.

Background on CAT6 Gel Filled Cable

TrueCable's CAT6 Gel Filled Direct Burial Ethernet Cable is different than their other direct burial cables in that it does not have waterproof tape around it. Instead, it has a tacky paraffin wax and mineral oil mixture inside to protect the cable. This gel filling is said to not be toxic. However, one common question that comes up is whether or not the gel inside makes the cable flammable.

The Flammability Test

To test this, Don decided to try lighting the cable on fire with a Zippo lighter. As he states in the video, he was very curious to see if it would actually burn. After several failed attempts at lighting different parts of the cable, it was clear the cable was not catching fire or burning like other common plastics or materials might.

The Results

As Don shows, the CAT6 gel filled cable simply would not ignite or sustain a flame when exposed to an open lighter flame. At most, it might char or smoke briefly in one small spot before self-extinguishing. This confirmed that the gel mixture inside the cable does not make it flammable or pose a fire risk. Network installers and homeowners can feel safe using this cable type without worrying about flammability.

FAQs

What type of gel is used inside the cable?

The gel mixture is a combination of paraffin wax and mineral oil, which provides moisture protection without being toxic.

How does the gel protect the cable?

As a gap-filling compound, the gel is tacky and helps prevent water ingress into the cable. It displaces any moisture and protects the internal conductors and insulation.

What applications is this cable best for?

As a direct burial cable, the CAT6 gel filled version is ideal for outdoor installations like connecting buildings underground. It can withstand burial underground without the need for additional waterproof jacketing.

Is the gel hazardous in any way?

No, the gel filling is non-toxic and poses no hazards. It will not ignite or sustain burning as shown through TrueCable's flammability testing.

In conclusion, TrueCable's flammability test of their CAT6 Gel Filled Direct Burial Ethernet Cable laid concerns about flammability to rest. The results clearly showed this cable type performs safely and as designed for low-voltage networking applications.
