Triplex URD cable: two phase conductors + bare neutral. Lower voltage drop, fewer terminations. XLPE 90°C.
Application
ANSI/ICEA S-81-570 triplex secondary URD cable (600V) for single-phase underground secondary distribution from pad-mounted transformer to residential or light commercial service entrance. Construction: two XLPE-insulated 1350-H19 aluminum phase conductors twisted with one bare neutral, 90°C rating. Direct burial or duct in wet/dry locations.
Core Strengths
Separate phase and neutral cables in single-phase buried installations risk stray voltage and mechanical damage. Our triplex URD brings both phase conductors and neutral in one assembly, lower voltage drop, fewer terminations. XLPE insulation, 90°C rated.
Standard
IEC227, BS6004, ANSI
Construction
☉〉 Phase conductors: 2 × aluminum (or AA-8000 series)
☉〉 Insulation: XLPE (for phase conductors)
☉〉 Neutral conductor: 1 × aluminum (bare or insulated, concentric or separate)
☉〉 Assembly: Three conductors twisted together (triplex configuration)
Features
☉〉 Rated voltage: 600V
☉〉 XLPE insulation provides high ampacity and 90°C continuous operation
☉〉 Triplex design offers compact, flexible cable for underground secondary distribution
☉〉 Moisture- and heat-resistant for direct burial or conduit installation
☉〉 Lightweight aluminum reduces installation cost compared to copper
