USE-2 Wire for Solar Applications

USE-2 Wire for Solar Applications


USE-2 is a single conductor, cross-linked polyethylene (XLP/XLPE) Type of solid or stranded bare annealed copper. The insulation is sunlight resistant and operates at 600V or 2000V.


USE-2 is suitable for all solar wiring solutions as interconnection wiring of grounded photovoltaic power systems.


Tough insulation that’s heat, moisture, oil and gasoline resistant, withstands high temperatures and harsh conditions, and its black insulation resists ultraviolet sun light very well, and can therefore be used with no issue in outside applications.


Our USE-2 is produced to the following specifications and requirements:

  • UL
  • ASTM

Available Products

  • Sizes #14 through 1/0 AWG
  • Solid or Stranded
  • Up to 12 color options for all sizes
  • Standard insulation is XLP, with XLP-VW-1 available when needed
  • Standard product operates up to 600 V, with 1000 V (1kV) and 2000 V (2kV) RHW-2 capacity options available when needed

We also have Photovoltaic (PV) Wire available for the solar industry.
