Applications and Usage


 

Which conduit should I use in high impact areas?

For special applications, XWall conduit with a thickness of .25″ can be used. Many of the telephone companies use this type of conduit for protection of fiber optic cables in above ground installations. XWall conduit has been shown to stop a .22 caliber bullet.

Use the Champion Fiberglass Conduit Calculator to estimate possible savings when using Champion Haz Duct® XWall Type Conduit vs. other in-market conduit materials.

How do I determine the proper conduit to use for Under Bridge applications?

Please refer to the deflection charts on pages 58 – 61 in the Engineering section of this catalog. After determining the weight of the cable and maximum allowable deflection (typically not exceeding 5/8″ or 16mm), use the deflection charts for selection of conduit type and support distance. See updated support spacing distances for Champion Fiberglass conduit (RTRC) here.

Use the Champion Fiberglass Conduit Calculator to estimate possible savings when using Champion Fiberglass Conduit vs. other in-market conduit materials.

What kind of conduit should be used in Core Boring applications?

Because of the possibility of high pressure caused by concrete, Heavy Wall conduit should be used for 4" – 6" diameter conduit. It is very important that the contractor/installer observes proper procedures when pumping the concrete into the core. If excessive pressure is applied, even Heavy Wall conduit may fail. Please contact Champion Fiberglass with questions on any of the above situations.

Once you’ve determined the correct conduit to use in your application, use the Champion Fiberglass Conduit Calculator to estimate possible savings when using Champion Fiberglass Conduit vs. other in-market conduit materials.

Which Champion Fiberglass conduit should be used in Direct Buried applications?

Direct Buried (or DB quality) applications should utilize UL Listed conduit. Use Standard Wall for 3/4" – 4" diameter, and Medium Wall for 5" and 6". For very deep trenches, special soil conditions or where high rate of compacting can be expected, an even heavier wall should be selected. Please contact Champion Fiberglass with questions on any of the above situations.

Which Champion Fiberglass conduit should be used in Encased Burial applications?

Encased in concrete (EB quality) applications can utilize Standard Wall product in most cases. Due to its high temperature rating, fiberglass conduit holds up very well for concrete encasement. (This application does not include core boring.) If UL listed material is required, use standard wall for 3/4" – 4" diameter, and Medium Wall for 5" and 6" diameter.

How can Champion Fiberglass conduit help drive project savings?

Champion Fiberglass offers many opportunities to save, from a lower starting material cost to lower manpower and installation costs. Visit our comparison chart to weigh the benefits, or visit our blog to learn more about how our newly extended support spacing distances help build savings.

You can also view our updated UL Listed support spacing distances in comparison to PVC-coated steel and GRC, and make a direct material and installation comparison using our Conduit Calculator.

If you’d like to discuss actual numbers, please contact us – we’d be happy to review any project spec or details and demonstrate your opportunities to save with Champion Fiberglass.

What is the difference between above ground and below ground conduit?

The main difference is in fire resistance. Above ground conduit has fire resistance per UL2515 and CSA C22.2 No. 2515 standards, meaning that the conduit will self-extinguish within 15 seconds after each of five successive flame applications per the UL 2515 flame test standard.

Below ground conduit meets UL94 HB (horizontal burn) requirements, which aren’t as stringent as vertical burn requirements. This also means that conduit manufactured and labeled for “above ground” applications can be used for “below ground” applications.
