ÖLFLEX® SOLAR XLWP

Benefits

• Robust against mechanical impact, for instance in case of unprotected burial in professionally made cable trench: Additional impact tests per UL 854
• The alternative for water coverage, e.g. due to elevated water line caused by flooding
• Reduction of flame propagation and of toxic combustion gases in the event of fire
• Extruded colour stripe serves as reverse polarity protection during installation.
• Exact quantity control during installation by meter marking on the cable sheath

Application range

• Photovoltaic systems with DC system voltage up to 1800 V to ground
• For the cabling between the solar modules and as extension cable between the module strings and the DC/AC inverter
• Underground use without protection conduit/ duct in professionally built cable trench with at least 50 cm of back-fill soil (70 cm underneath roads), above indicating tape, above covering plastic slab, above at least 10 cm of covering sand layer, above the cable laid on at least 10 cm high sand bed layer (cf.: Section 4.2 of VDE 0891-6, or Section 300.5 in Article 300 of NFPA 70/ NEC - National Electrical Code of the USA)
• In September 2018 and based on AD8 watertightness and particularly watertight design, this product was recommended by Solartechnik Bayern for underground use typically realized via underground conduits/ ducts (...) for PV applications; Damp build-up of contaminated water inside underground conduit/duct shall be avoided
• The expected service life at normal use conditions in line with EN 50618 amounts to 25 years
