Feltoflex® LED Self-Luminous Single Core Cable addresses this application niche with revolutionary integration of electromagnetic induction self-powered LED illumination into a premium single-core cable architecture. Unlike three-phase mining cables designed for kilometre-long trunk distribution, Feltoflex LED cables serve the critical short-distance interconnection role—where visibility, flexibility, durability, and compact form factor are paramount. Switchgear rooms and transformer chambers are typically underground or in poorly lit industrial areas. When technicians need to work on cable terminations, identify connection points, or troubleshoot equipment, they currently rely on portable lamps, headlamps, or external lighting. The Feltoflex LED cable illuminates itself as it carries power, providing integrated visibility that enhances safety, accelerates maintenance procedures, and requires zero external infrastructure.

RHEYFIRM® (S) series reeling cables with 3+3 core distributed earth design exhibit outer diameters ranging from approximately 40.0 mm (for 3×25+3×25/34 mm² configurations at 6/10 kV) to 76.0 mm or larger (for heavy-duty 3×185+3×95/35 mm² configurations at 12/20 kV). The nominal outer diameter depends on the specific conductor cross-section, voltage rating, and insulation thickness selected. For a typical medium-voltage marine and industrial application, a RHEYFIRM® (S) cable rated 3×70+3×35/32 mm² at 6/10 kV exhibits an outer diameter between 52.0 mm and 56.0 mm with approximate total cable weight of 4,300 kg/km (2,890 lbs/1000ft), while the corresponding 12/20 kV variant reaches 62.0 to 67.0 mm outer diameter with weights near 6,800 kg/km (4,570 lbs/1000ft).
