- UL® Recognized
- Highly Flame Resistant
- Arc & Track Resistant
- Uncommon Dimensional
Stability
- Strong & Durable; Yet
Easily Cut & Chamfered
- Cost-Effective
Grade UTR Pultruded Tubing is a fiberglass
reinforced thermoset polyester composite in a pultruded tube. It is
recognized by Underwriters Laboratories. It is flame resistant, track resistant. and it has a UL index
rating of 130°C electrical and 160°C mechanical.
Grade UTR tubing exhibits
uncommon dimensional stability. It
is impervious to high humidity or immersion. It is also strong
and durable (with a burst strength of 1200 psi to 1400 psi); yet it
is easily chamfered and cut with carbide or diamond saws.
Pultruded Tubing Composites
are ideal for numerous tubing applications, and commonly used for
a wide variety of fuses, from simple 15 amp fuses to heavy-duty 600
amp fuses. They are available in virtually any length or size in the
standard color black; yet they can be customized to accommodate a
range of other color preferences. |

1. Tubes are tested for porosity by applying
water pressure for 60 seconds to the inside. No streams of water should
be visible at the listed pressure.
2. NEMA LI-1 specifies arc resistance of 150 seconds on a .125" thick
sample. Thinner sections exhibit lower arc resistance.
