- GPO3 TUBE UTR Composite PultrudedTubing GPO-3
- Highly Flame Resistant
- Arc & Track Resistant
- Uncommon Dimensional Stability
- Strong & Durable; Yet Easily Cut & Chamfered
GPO3 Pultruded Tubing is a fiberglass reinforced thermoset polyester composite in a pultruded tube. GPO3 Pultruded Tubing is flame resistant, track resistant. and it has a UL index rating of 130°C electrical and 160°C mechanical. GPO-3 tubing exhibits uncommon dimensional stability. It is impervious to high humidity or immersion. GPO3 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. 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.
