Product Overview
Quadruplex URD Cable is a 600V secondary underground residential distribution cable with three aluminium phase conductors and one aluminium neutral, all XLPE insulated and cabled together. Manufactured to ICEA S-105-692 and UL 854 as UL Listed USE-2, RUS accepted for utility-grade installations. Conductors are Class B compressed concentric lay stranded 1350-H19 or AA-8000 aluminium alloy per ASTM B231 / B800 / B801. Phase conductors are black XLPE; the neutral is identified by yellow striping or a full yellow jacket per US utility convention. Rated 90°C in dry, wet, and direct burial conditions, with chemical, heat, ozone, oil, and abrasion resistance. Quadruplex URD is the standard cable from pad-mount transformer to residential service entrance in North American secondary distribution networks.

Commercial Service
Three-phase 600V service to small commercial buildings, retail units, and multi-tenant properties from underground transformers.
Direct Burial in Earth
Rated for direct burial without conduit. XLPE insulation provides moisture, chemical, and soil acid resistance for decades of underground service.
Duct Installation
Suitable for pulling through underground ducts in both wet and dry locations. USE-2 listing covers all underground service entrance applications.
US Utility Networks
ICEA S-105-692 and RUS accepted. Fully compliant with US electric utility standards for secondary URD applications.
Subdivision Development
New residential and commercial subdivisions where underground distribution is mandated by local code or aesthetic requirements.
