"An advanced, high-voltage single-conductor solution engineered for the critical interconnection wiring of both grounded and ungrounded solar power systems. Built to withstand high-capacity energy generation, this 350 MCM aluminum PV wire provides a lighter, exceptionally cost-effective alternative to copper for commercial utility arrays, field distribution blocks, and renewable energy grids."
Outdoor solar setups require components that stand up to the elements. This 350 MCM solar pv cable delivers dependable service by surrounding a high-grade, 35-strand compact AA-8000 aluminum core with a rugged, UL-listed Sunlight Resistant (SUN RES) cross-linked polyethylene (XLPE) insulating barrier. The thick insulation shield is specifically designed to brave severe outdoor exposure, resisting intense solar UV rays, seasonal frost, shifting soil conditions, and common field chemicals without snapping or wearing down.
High-Capacity 2000V Threshold: Engineered safely for systems running up to 2000 Volts to easily accommodate modern, high-output commercial solar configurations.
Code-Approved Tray Placement: Meets all requirements under NEC Article 690.31 (C) (2) for open, unprotected routing inside exterior cable trays.
Direct Burial and Sunlight Resistant Armor: Formulated with a waterproof, UV-blocking XLPE jacket that is certified for both direct underground burial trenches and long-term, exposed outdoor placement.
Extreme Weather Performance: Engineered to stay structurally stable and completely flexible in temperatures from -40°C up to +90°C.

Under normal operational guidelines at a standard conductor temperature of 90°C(wet or dry), a single conductor of 350 kcmil Aluminum 2kV PV wire features an allowable ampacity rating of 280 Amps. If your project calls for terminating to a 75°C terminal lug, the calculated ampacity adjusts downward to 250 Amps per National Electrical Code (NEC) guidelines.
Yes, it is fully rated and certified for direct underground burial. This solar wire is constructed with a rugged Cross-Linked Polyethylene (XLPE) insulation jacket and it carries triple-listing compliance under UL 4703 (PV Wire), UL 44 (RHW-2), and UL 854 (USE-2). This guarantees permanent waterproof protection and high soil-chemical resistance without necessitating conduit.
es, absolutely. In accordance with NEC Article 690, single-conductor aluminum PV wire sizes 1/0 AWG and larger are fully approved for deployment in outdoor exposed or concealed cable trays. The XLPE insulation is fundamentally engineered with maximum Sunlight Resistant (UV) and ozone protection to prevent fracturing over decades of direct exposure to intense solar fields.
