50cm super soft silicone wire

The cable that won't hinder your setup: super soft 28AWG silicone wire in 50 cm

When preparing a slot car for competition or simply wanting a clean and professional interior finish, the stiffness of the wire can become the biggest enemy. This super soft silicone wire from Avant Slot (ref. AV20804) solves that problem at its root: with its standardised section of 28AWG and its highly flexible silicone sheath, it adapts to any routing without straining connections or taking up unnecessary space.

Main features

• Section: 28AWG, standardised for electrical installations in slot.
• Length: 50 cm per unit, sufficient for multiple runs in a single car.
• Super soft silicone sheath: withstands heat better than conventional PVC and does not harden over time.
• Multi-strand construction: the core of very fine strands provides exceptional flexibility, reducing mechanical stress on the solder joints.

Function and performance

In a slot car, the electrical installation must conduct current with the least resistance possible while not interfering with the freedom of movement of the motor, guide, or chassis. The 28AWG gauge is well-sized for the usual currents in 1:32 and 1:24 slot cars, and the multi-strand construction reduces electrical resistance compared to wires of the same gauge but with fewer strands.

The silicone sheath withstands higher temperatures than standard PVC, which is particularly useful near motors that operate at their limits or during long club sessions.

Installation and preparation

Its high flexibility allows the wire to be bent and routed at tight angles without the insulation cracking or the core being damaged. This greatly facilitates preparation tasks such as:

• Wiring between braids and motor in tight chassis.
• Connecting decoupling capacitors directly to the motor terminals.
• Renewing the original wiring in cars that will compete in open preparation categories.

It solders easily with standard electronics solder. We recommend stripping only the exact millimetres of sheath to avoid short circuits in tight working areas.

Compatibility

As a universal specification 28AWG wire, it is compatible with any slot car regardless of the brand: Avant Slot, Scaleauto, Slot.it, NSR, Scalextric, Ninco, Carrera, and any other that uses wiring of this gauge. It is also useful in static models or dioramas where simulating scale wiring or making LED lighting connections is required.

Frequently asked questions

What is the difference between a 28AWG silicone wire and a PVC one?

Silicone is much more flexible than PVC, especially when cold, and withstands higher temperatures without degrading. This makes it preferable in competitive environments where the motor may heat up during prolonged sessions.

Is 50 cm enough to wire a complete car?

It depends on the chassis design, but in most 1:32 slot cars, 50 cm can provide several internal runs. For more complex installations or if you want to have spare wire, it may be advisable to purchase more than one unit.

Does multi-strand improve electrical conduction compared to a single-strand wire of the same gauge?

Yes. At the same total section, the multi-strand conductor offers slightly better conduction and, above all, much greater resistance to fatigue from repeated bending, which extends the lifespan of the connections.

Can I use it to connect LEDs in models or dioramas?

Absolutely. Its flexibility and reduced section make it very manageable for small-scale lighting installations in static models and dioramas.

Is it necessary to use any special type of solder?

No. Any electronics solder with a flux core is sufficient. A fine soldering tip and controlled temperature are recommended to avoid damaging the silicone sheath during the process.
