Ul 4703 Cable vs. Other Types of CableApplicationsTemperature RatingFlexibilityInsulation and JacketTesting RequirementsPV wire is made up of stranded copper conductors, which makes it flexible. USE-2 wire is usually installed in locations where it is not subject to movement or mechanical damage, so they can use either solid or stranded conductors made of copper, copper-clad aluminum, or aluminum, making it less flexible than PV wire.See more on temcoindustrial
