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).

How do EMC-compliant VDE cables like (N)2XCCY differ structurally from standard screened mining cables like (N)TSCGEWÖU?

The distinction between EMC-compliant distribution cables such as the N2XCCY series manufactured according to DIN VDE 0276-620 standards and heavy-duty mining cables like the NTSCGEWÖU series designed per DIN VDE 0250-813 specifications reveals how cable construction must adapt to specific electromagnetic environments and mechanical demands. Understanding these structural differences provides essential insight for engineers specifying cables in installations where electromagnetic interference control is paramount alongside mechanical reliability.
