ProcedureFiberglass conduit and sweeps must be blackwith three red stripes to identify electricconductors inside. For complete specificationson fiberglass conduit request a copy ofmaterial specification ZG033, or find thisspecification at www.rockymountain.net/ESRFigure 2.2.5.1 – Fiberglass ConduitFigure 2.2.5.2 – Electrical Grade PVCFigure 2.2.5.3 – Fiberglass SweepsAdditional conduit and sweep requirements and comments:• PVC shall be electrical grade 40 or better• Fiberglass conduit shall meet or exceed the Power Company’s materialspecification ZG033J:\Publications\FPP\DIS\PRO\242-RMP Underground Conduit Systems.docx R6, 5/13/14This document is posted online at rockymountainpower.net, and at engineering’s intranet site for distribution procedures.Modification of this document must be authorized by PacifiCorp engineering publications, (503) 813-5293. 6
• Each fiberglass sweep requires two factory-attached PVC, extra-deep,fabricated, expanded bell-ends as shown in Figure 2.2.5.3.• Fiberglass sweeps must be certified by a Nationally Recognized TestingLabratory (NRTL).High-Density Polyethylene (HDPE) conduit may be used upon approval ofthe Power Company. HDPE conduit can be installed by plowing and shortdirectionalboring methods. Primary and secondary conductors can bepulled into this type of conduit. HDPE conduit shall meet the PowerCompany’s specification ZG031 which can be found athttp://www.rockymountainpower.net/con/esr.htmlProcedure2.2.6 Conduit and Sweeps - Installation1. The customer shall provide and install conduit, including long-radius sweeps.2. All PVC joints shall be glued and compressed to the depth of the couplingsystem. All fiberglass joints shall be glueless, using an interference andgasketed joint (see Figure 2.2.6.1), and shall be compressed to the depth ofthe coupling system. Where straight ends and bell ends are joined, the straightend shall be beveled so as not to become an obstacle to mandrels or pulledcable.3. Manufactured sweeps shall not be altered. However, field formed sweeps fromstraight conduit (PVC only) up to 15 degrees are allowed as long as themandral can be pulled throught the conduit and the conduit is not damaged.Figure 2.2.6.1 – Fiberglass End ConnectionsFigure 2.2.6.2 – Field Altered Sweep - Damaged PVCJ:\Publications\FPP\DIS\PRO\242-RMP Underground Conduit Systems.docx R6, 5/13/14This document is posted online at rockymountainpower.net, and at engineering’s intranet site for distribution procedures.Modification of this document must be authorized by PacifiCorp engineering publications, (503) 813-5293. 7
