Nexans AmerCable's Type PV UL4703 is now CSA listed as RPV-90 (LL80350). This is in addition to its UL Listings as 2000V Type PV (E322538) and RHH/RHW-2 (E76087).
Nexans AmerCable's Type PV UL4703 is a single-conductor cable that meets the newest standards as introduced in National Electrical Code (NEC) Article 690. Applications include connection to module junction boxes; required cable routing in balance of system (BOS) integration; and where also allowed by the NEC.
Type PV UL4703 features a two layer construction of flame retardant, oil and sunlight resistant Chlorinated Polyethylene (CPE) over an Ethylene-Propylene Rubber (EPR) inner layer. This design is based on a construction allowed for use on ungrounded systems as described in NEC Article 690 without the need for conduit when installed exposed. This construction provides greater protection from ozone weather and abrasion than other single layer constructions while maintaining flexibility for ease of installation.
