ROSSLYN, Va.—Today, the National Electrical Manufacturers Association (NEMA) released its standard for high-density polyethylene (HDPE) conduit. NEMA TC 7-2016 Smooth-Wall Coilable Electrical Polyethylene Conduit establishes requirements for several wall types of HDPE conduit used in raceways for electrical and communication cables buried underground or concrete encased. Applications include power distribution, site lighting, signal and control, and supervisory control and data acquisition.
"The new edition of NEMA TC 7 adds the definition for EPEC-15.5 HDPE and new dimensional and pipe stiffness requirements for this conduit type," said Andrew Nause, manager of codes and standards, electrical at IPEX Group, and chair of the Polymer Raceway Section Technical Committee. "Additionally, the standard specifies new UV stabilization and outdoor storage stability requirements."
NEMA TC 7-2016 is available for $72 in hard copy or as an electronic download on the NEMA website.
