RHEYHALON Solar about to receive TÜV approval in accordance with new requirements profile

Mönchengladbach, 20 August 2007 – With RHEYHALON® Solar, Nexans Deutschland Industries GmbH & Co. KG is now welcoming a cable into its product range which has been specially developed for use in photovoltaic (PV) equipment on the direct voltage side. Unlike the cables currently in use, this cable can withstand light, ozone or fungal attack, for example, and is therefore set to ensure secure operation for 25 and more years. It was developed in accordance with the new requirements catalogue for PV leads of the DKE, German Commission for Electrical, Electronic & Information Technologies of DIN and VDE, Frankfurt. TÜV Rheinland has already tested RHEYHALON® Solar for its resistance to cable corrosion. In Autumn of this year, it is set to be one of the first PV cables on the German market to receive TÜV approval.

RHEYHALON® Solar is suitable for voltages up to 1.8 kV*). In compliance with DIN EN 60228 (category 5), its conductor consists of tin-plated fine copper wires and is surrounded by insulation consisting of a meshed elastomer mix. This in turn is encased by a mix of polyolefins, which are meshed and are resistant to oil, the ozone and UV light. The insulation, which can also withstand heavy mechanical stress, has a resistance value of more than 1015 Ω x cm. Unlike commercially available rubber-insulated conductors, neither hair cracks nor age-related shrinkage of the coat is to be feared in the RHEYHALON® Solar. Even with respect to its properties in the event of a fire, it fulfils the TÜV criteria: its insulation is halogen-free, it does not release any toxic gases in the event of a fire and it prevents the fire from spreading. Nexans’ new PV cable is intended for operation at temperatures from -40 to 110 °C and is now available in five different nominal cross-sections of between 2.5 any 16 mm².
