The City of Ames is seeking quotes for 15kV, EPR cable for Electric Services. The cable should be jacketed, concentric-neutral, 220 mil ethylene propylene rubber (EPR) insulated, aluminum conductor underground residential distribution (URD) cable suitable for duct, direct buried and riser/outdoor applications. The cable manufacturer shall compound the insulation in its own facility, using a closed system that avoids contamination. The nominal insulation thickness shall be 220 mils. The minimum thickness of the insulation shall be 210 mils and the maximum thickness shall be 250 mils. The insulation shall be rated for a continuous operating temperature of 105°C, an emergency operating temperature of 140°C and a short circuit temperature of 250°C. • The cable shall be manufactured and tested under a declared Quality Management System (QMS) that is ISO registered. • The conductor shall be strand-filled aluminum alloy 1350 per ASTM B609, Class B concentric lay stranding per B-231. • The strand-filling compound shall completely fill the conductor’s inner strand layers. • The conductor shield shall be applied over the conductor, shall be an extruded, semi-conducting thermosetting compound and meeting the latest AEIC and ANSI/ICEA requirements. • The insulation shield shall be extruded, semi-conducting thermosetting compound applied over the insulation with appropriate thickness as per ICEA S-93-639. • The concentric neutral shall be annealed, solid, uncoated round copper wire. • The jacket shall be a black, non-conducting, linear low-density polyethylene (LLDPE) jacket shall be extruded over the concentric neutral. • The cable shall be shipped on non-returnable reels with at least one layer of weather-resistant material for protection of the cable. • A minimum of one-year warranty against any manufacturing defect.
