NSGAFÖU - The flexible rubber cable
Flexibility and durability, two qualities with which the NSGAFÖU rubber cable ensures a safe connection. The cable structure and the product qualities ensure that they retain their resistance even under thermal loads and external environmental factors. They are used, among other things, in pipes and closed installation ducts. They can be bundled thanks to the arrangements of cores according to VDE 0250 part 602 or installed as a connection for moving parts. With a rated voltage of 1.8/3 kV they are particularly suitable for short-circuit-proof and earth-leakage-proof installation. The NSGAFÖU cable from Lapp is used in many applications, for example in switchgear, buses, railway vehicles or distributors.

Meaning of the type designation NSGAFÖU
The letter N indicates that the NSHÖU wire is a standardised wire. The S stands for cord (German: Schnur) and indicates that the outer jacket is a canvas sheath. This makes the NSGAFÖU wire robust and helps it withstand even heavy mechanical loads. The letter G stands forrubber sleeve (German: Gummihülle) , which makes the cable suitable for higher temperature ranges. The A simply stands for Core (German: Ader) or core cable. The letter Ö stands for oil-resistant (German: ölbeständig) and the U for flame-retardant.
The NSGAFÖU core cable can be interpreted as follows:
- N – standardised wire according to VDE 0280 T.602
- S – Cord and material of the outer sleeve canvas
- G – Rubber sheath as outer jacket and core insulation
- A – Core/core cable
- F – conductor type; fire-core conductor
- Ö – oil-resistant
- U – non-flammable/flame-retardant according to VDE 04822-332-1-2 / IEC 60332-1-2
Areas of application for NSGAFÖU rubber cables
The short-circuit-proof NSGAFÖU rubber cables from Lapp are short-circuit-proof and earth-leakage-proof for rated voltages up to 1000 V and guarantee installation in accordance with VDE 0100 part 520 and VDE 0298 part 3. They are used for reliable cabling on machines, in public transport such as railway vehicles and in vehicle manufacturing, for example in coaches and for cabling in switch cabinets and for device cabling. It is also used in order to establish a connection between distributor circuits and downstream overcurrent protection.

The NSGAFÖU rubber cables as a reliable connection
The short-circuit-proof rubber cable is made from fine-core, tin-plated copper threads. As a result of the material of the outer jacket, a polychloroprene rubber mix (5Gm3)the wire withstands even heavy mechanical loads. The core insulation comprises a rubber sheath, a special rubber mix without added colours – making the cable suitable for applications with high temperatures. In motion, the permissible outer temperature is -25° C to 80° C, permanently installed, the temperature range is between -40° C and 80° C. It is therefore suitable for flexible applications and without tension relief in dry areas. Direct underground installation is not permitted if there is no fire protection bulkhead. The minimum bend radius moved of 10.0 x outer diameter and permanently installed 6.0 x outer diameter ensures flexible installation of the Lapp NSGAFÖU. With regard to fire behaviour, the wires are flame-resistant according to IEC 60332-1-2 and self-extinguishing and largely oil-resistant.
