NSGAFCMOEU 3.6/6kV Screened Heating Circuit Cable

NSGAFCMOEU Screened Heating Circuit Cable

NSGAFCMOEU is a 3.6/6 kV screened single-core cable to DIN VDE 0250 Parts 602 and 606, designed for higher mechanical stressing, typically as the connection element for heating circuits in trucks, buses and track-bound vehicles. The screen, denoted by the CMOE letters, is a helix of tinned copper wires laid over the insulation; it is what separates this cable from the unscreened NSGAFÖU base build.

The page also covers NSHXAFCMOE, the halogen-free equivalent. The two share the screened construction and differ in sheath compound, and that difference changes the bending radius: 4 × D for the chlorinated-rubber NSGAFCMOEU against 6 × D for the halogen-free NSHXAFCMOE. Both are supplied in 185 mm², which is the maximum cross-section that DIN VDE 0250 Part 602 sets for this voltage class.

• Rated voltage: 3.6/6 kV.
• Screen: helix of tinned copper wires (CMOE).
• Cross-section: 185 mm², the Part 602 ceiling for this class.
• Bending radius: 4 × D screened chlorinated rubber; 6 × D screened halogen-free.

For the unscreened base builds use NSGAFÖU and NSHXAFÖ, which cover 1.5 mm² to 300 mm² and are a different specification entirely.

NSGAFCMOEU Cable Construction

Four-layer screened single-core construction. The inner semi-conducting layer is present on the 6 kV build, and the CMOE screen sits between the insulation and the sheath.

NSGAFCMOEU Applications

The screened CMOE builds are designed for higher mechanical stressing, for instance as the connection element for heating circuits in trucks, buses and track-bound vehicles. The unscreened builds of the same family are used for fixed installation in vehicles, in conduits and closed installation systems, and in low-voltage switchboards; those applications stay on their own pages.

• Heating circuit connections in trucks, buses and track-bound vehicles.
• Routes with higher mechanical stressing than the unscreened build is rated for.
• Installations requiring a metallic screen over a single-core medium-voltage connection.
• Halogen-free variants where low smoke emission is specified, using NSHXAFCMOE.

Application boundaries

The screened builds are supplied in 185 mm² only. Do not read the 1.5 mm² to 300 mm² range of the unscreened NSGAFÖU and NSHXAFÖ tables across to this page; those are different cables with a different construction and different current ratings. State the screen termination and earthing method, the heating circuit rating and the vehicle interface with the enquiry.

Reference note: enquiries arriving marked NSGAFCMÖU or NSGAFCMOU are handled on this page; umlaut and OE spellings refer to the same designation.

NSGAFCMOEU Specifications

NSGAFCMOEU and NSHXAFCMOE 3.6/6 kV size table

185 mm² is the maximum cross-section that DIN VDE 0250 Part 602 specifies for this voltage class, so the single-row table is the complete screened range rather than an extract. Sustained current loading is stated at 30 °C ambient, free in air, as in DIN VDE 0298 Part 4 Table 11, and must be corrected for the installed condition. The nominal fire load figure applies to the halogen-free NSHXAFCMOE build.
