Is NSHXAFÖ 1.8/3 kV right for your machine?

Halogen-free (LSZH) VDE 0250-602 1.8/3 kV single-core flexible power wire for enclosed rail coaches, marine switchboards and public-building switchgear.

Switchgear & control cabinet wiring

Suitable

Primary duty — halogen-free, earth-fault-proof single-core bus and breaker wiring inside switchgear and rail cubicles.

Motor stator, traction & converter leads

Suitable

Low-smoke converter, traction motor and auxiliary inverter jumpers in passenger rail and tunnels.

Fixed installation

Suitable

Fixed routing in closed ducts, trays and machine frames where low smoke/zero halogen is mandatory.

Immersion & wet locations

Not suitable

LSZH compound is for dry/damp indoor or enclosed vehicle use, not permanent water immersion.

Use H07RN8-F Submersible

Motorised monospiral reel

FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

Which VDE standard governs NSHXAFÖ versus NSGAFÖU?

NSGAFÖU with a chlorinated 5GM3 rubber jacket is standardized under DIN VDE 0250-602. NSHXAFÖ with a halogen-free, low-smoke FRNC outer jacket (compound type HM3) is standardized under DIN VDE 0250-606, while retaining the same 1.8/3 kV voltage class, 3GI3 EPR core insulation and short-circuit-proof rating up to 1,000 V.

What does the 'HX' in NSHXAFÖ denote?

In VDE cable nomenclature, 'HX' denotes a cross-linked halogen-free polymer compound (HM3), verifying that the cable meets DIN EN 50267 / IEC 60754 for zero halogen acid gas and DIN EN 61034 / IEC 61034 for low smoke density in fire conditions.

Is NSHXAFÖ available in 3.6/6 kV or with a metallic screen?

Yes. Alongside the standard 1.8/3 kV series (1.5 to 500 mm²), NSHXAFÖ is manufactured in a 3.6/6 kV series with an inner semi-conductive conductor layer (1.5 to 185 mm²), and as NSHXAFCMÖ with a concentric tinned copper wire screen.

Why is the 1×400 mm² outer diameter listed as 34.6–40.0 mm?

In the original PDF table for 1.8/3 kV, the Min. OD (40.0 mm) and Max. OD (34.6 mm) columns for 1×400 mm² were accidentally transposed. The physical minimum-to-maximum diameter tolerance is 34.6 mm to 40.0 mm.
