NSGAFÖU 1.8/3 kV is a flexible, VDE-approved single-core rubber cable used for power connections requiring high mechanical strength. It is commonly installed inside switchboards, control cabinets, industrial machinery and electrical equipment.
When installed according to the relevant requirements, NSGAFÖU cable is suitable for short-circuit-proof and earth-fault-proof wiring in electrical systems operating up to 1,000 V.
LAPP Australia supplies a wide range of NSGAFÖU 1.8/3 kV single-core rubber cables. The range is locally stocked, available for delivery across Australia and supported by an experienced Australian team that can assist with product selection and technical enquiries.
What does NSGAFÖU mean?
NSGAFÖU is the designation for a standardised VDE cable type. It is not a proprietary LAPP product name.
The cable is manufactured according to DIN VDE 0250-602 and typically features:
- A fine-stranded, tinned-copper conductor
- EPR rubber conductor insulation
- A durable rubber outer covering
- Class 5 conductor flexibility
- Oil-resistant properties
- Flame-retardant performance
- A rated voltage of 1.8/3 kV
This construction gives the cable the electrical insulation, flexibility and mechanical protection needed for demanding equipment wiring.
The name is also commonly written online as NSGAFOU without the umlaut. Both terms refer to the same cable type.
What does the 1.8/3 kV rating mean?
The voltage rating is written as U₀/U:
- U₀, 1.8 kV: rated voltage between the conductor and earth
- U, 3 kV: rated voltage between conductors
The 1.8/3 kV rating provides a higher insulation level than standard low-voltage panel wire. This supports its use in installations where mechanical damage could increase the risk of a short circuit or earth fault.
It does not mean the cable can only be used in 3 kV systems. NSGAFÖU may be used for short-circuit-proof and earth-fault-proof installation in systems up to 1,000 V when the required installation conditions are met.
What is a short-circuit-proof cable?
A short circuit occurs when current flows through an unintended low-resistance connection between live conductors. This can produce a high fault current, heat and equipment damage.
A short-circuit-proof cable has the insulation strength and mechanical construction needed to reduce the risk of a conductor-to-conductor fault.
The term does not mean the cable prevents every electrical fault. Cable sizing, routing, protection devices and installation methods must still comply with the relevant electrical standards and project requirements.
What does earth-fault-proof mean?
An earth fault occurs when a live conductor makes unintended contact with earth or an exposed conductive component connected to earth.
Earth-fault-proof installation reduces the likelihood of this contact occurring if the cable is exposed to mechanical stress or insulation damage.
NSGAFÖU supports this type of installation through its high mechanical strength, rubber insulation and protective outer covering. Correct routing, termination and circuit protection remain part of the complete electrical design.
What are the benefits of NSGAFÖU cable?
Short-circuit and earth-fault protection
NSGAFÖU cable can support short-circuit-proof and earth-fault-proof installation up to 1,000 V when used with an approved installation method.
Flexible conductor
The fine-stranded Class 5 conductor makes the cable easier to route through switchboards, machinery and control cabinets than a solid or coarse-stranded conductor.
High mechanical strength
Its rubber insulation and outer covering provide added protection in applications exposed to mechanical stress.
Oil resistance
NSGAFÖU can be used in dry and oily industrial environments, making it suitable for many machinery and equipment applications.
VDE-approved construction
The cable is approved according to VDE 0250-602, providing engineers and equipment manufacturers with a recognised cable specification.

Where is NSGAFÖU cable used?
Common applications include:
Switchboards and distribution boards
Control cabinets and electrical panels
Wiring circuits inside industrial machines
Electrical equipment and appliance wiring
Enclosed ducts and installation channels
AC and DC charging infrastructure
Rail vehicles and buses where the relevant standards permit
Dry or oily industrial environments
Connections requiring flexible single-core wiring
The cable is primarily intended for fixed installation. Flexible construction makes routing and termination easier, but this does not automatically make it suitable for continuous movement.
Is NSGAFÖU suitable for switchboard wiring?
Yes. Switchboards, control cabinets and distribution equipment are among the main applications for NSGAFÖU cable.
The fine-stranded conductor assists with installation in confined areas, while the rubber insulation and outer covering provide a high level of electrical and mechanical protection.
For example, NSGAFÖU 1.8/3 kV 1 x 2.5 mm² may suit smaller equipment connections. Larger conductor sizes are available for applications carrying higher current.
Is NSGAFÖU suitable for continuous movement?
NSGAFÖU has a flexible Class 5 conductor, but it is primarily designed for fixed installation and occasional movement.
It should not be selected for drag chains, robotic systems or applications involving continuous bending without confirming its suitability. These applications usually require a cable engineered and tested for repeated flexing.
Is NSGAFÖU the same as H07RN-F rubber cable?
No. Both are rubber cables, but they are designed for different applications.
NSGAFÖU is a single-core, 1.8/3 kV cable commonly used for protected power connections, internal equipment wiring and short-circuit-proof or earth-fault-proof installations.
H07RN-F is generally a flexible multicore cable used for portable equipment, power supplies, tools, pumps and outdoor industrial applications.
The correct choice depends on the voltage, number of conductors, installation method, mechanical conditions and required approvals. View the broader LAPP Australia rubber cable range to compare available options.
