Understanding TFFN Wire
TFFN stands for Thermoplastic Flexible Fixture Nylon. It is a single-conductor wire with the following structure:
Conductor: Typically made of soft-drawn copper, often stranded for flexibility.
Insulation: A layer of PVC (polyvinyl chloride) for thermal and electrical insulation.
Jacket: A nylon sheath that adds abrasion resistance and chemical protection.
TFFN wire is rated for 600 volts and a maximum temperature of 90°C in dry locations, making it suitable for both dry and damp environments.
Common Applications of TFFN Wire
Because of its design, TFFN wire is ideal for use in:
Residential and commercial lighting fixtures
Conduit installations in buildings
Control wiring in electrical panels
Industrial automation systems
Its nylon jacket gives it added strength and resistance in environments where mechanical protection is crucial.
TFFN vs. TF Wire: What’s the Difference?
If you’re searching for terms like “what is TFFN wire” or “TFFN wire meaning”, you might also come across TF wire. Here's how they differ:
TF wire: Thermoplastic Fixture wire without the nylon jacket.
TFFN wire: Comes with a nylon coating, making it more durable and resistant to abrasion and chemicals.
When mechanical strength and longevity matter, TFFN is the better choice.
Popular TFFN Wire Sizes
Some commonly searched and used TFFN wire types include:
16 AWG TFFN wire
18 AWG TFFN wire
18 TFFN stranded wire
TFFN wires for general conduit wiring
These wire sizes are frequently used in lighting circuits, control panels, and terminal connections.
Why Electricians Prefer TFFN Wire
Here’s why professionals and contractors choose TFFN wire:
✅ Flexible and easy to install
✅ UL-listed and safety compliant
✅ Nylon jacket resists oil, chemicals, and moisture
✅ Reliable performance at a lower cost
Whether you’re updating a commercial building or wiring new residential units, TFFN wire delivers a solid, cost-effective wiring solution.
