RPVU90 is a single conductor cross-linked polyethylene (XLP or XLPE) wire that can operate in photovoltaic (PV) systems at 600 V, 1000 V (1kV), or 2000 V (2kV) and is suitable for AC and DC systems.

This wire is rated for continuous operation in temperatures of 90°C in wet and 105°C in dry locations.


This product is used for interconnection wiring of grounded and ungrounded photovoltaic power systems at various voltage levels.


RPVU90 wire is oil, gasoline, and sunlight resistant. It is also rated for direct burial.
