Oxygen-free silicone electrical wire

When electricity flows without resistance: the OFC cable from Sloting Plus

Wiring is one of those details that separates an amateur installation from a truly well-prepared setup. This silicone electric cable from Sloting Plus (reference SP107031) is made with oxygen-free copper wire —Oxygen Free Copper, OFC— and contains more than 70 ultra-fine copper strands twisted inside its 1.5 mm diameter.

Main features

• OFC conductor (Oxygen Free Copper): oxygen-free copper offers superior electrical conductivity compared to standard copper and has a much higher resistance to oxidation, resulting in a cleaner and more stable signal over time.
• More than 70 copper strands inside: the high number of extremely fine strands is key to its mechanical behaviour. The more strands, the more flexible the cable is, making it less prone to breaking from fatigue in areas of continuous movement.
• Silicone sheath: silicone is the material of choice for demanding insulation. It withstands heat well, does not harden in the cold, and maintains its elasticity for years, unlike conventional PVC.
• Diameter Ø 1.5 mm: a versatile gauge, manageable and easy to pass through narrow conduits.
• 2-metre bag format: a practical quantity for several interventions or to completely renew the wiring of a car.

Applications and use in slot

This cable is designed for preparers and enthusiasts who want the best at every point in their slot car's electrical chain. Its most common applications are:

• Connection between the braids and the motor, minimising signal loss.
• Internal wiring of custom or prepared chassis.
• Replacement of factory wiring when looking to reduce electrical resistance and improve throttle response.
• Any installation that requires a flexible, durable, and low-profile cable.

Why oxygen-free copper matters

In high-frequency applications or control signals like those of a slot car, the purity of the conductor influences the response. OFC eliminates micro-impurities of oxygen that in ordinary copper act as additional resistance points. The result is more efficient conduction and a material that withstands the heating and cooling cycles typical of intensive track use much better.

Assembly and preparation

When working with cables made of many fine strands, it is advisable to use precision stripping pliers to avoid cutting strands when removing the insulation. Before soldering, it is recommended to tin the strands in groups so that they remain joined and the soldering is clean. Silicone does not tolerate prolonged heat from the soldering iron well, so it is ideal to apply heat quickly and directly.

Frequently asked questions

How much cable does the bag contain?

Each bag contains 2 metres of cable, sufficient for several interventions or to completely wire more than one car.

What real advantage does OFC offer over standard copper cable?

Oxygen-free copper has slightly superior conductivity and, above all, greater resistance to internal oxidation. Over time and with use, an OFC cable maintains its electrical performance better than a conventional copper one.

Is it compatible with any slot car?

Yes. Being a generic cable with a diameter of 1.5 mm, it can be used in any car or installation that requires wiring of that gauge, regardless of brand or scale.

Why is cable flexibility important in a slot car?

Inside a slot car, space is very limited, and the cable is subject to bends and movements. A less flexible cable can break from fatigue or make assembly difficult. The more than 70 fine strands of this cable provide it with flexibility that facilitates work and extends its lifespan.

Can I also use it for other modelling or electronics applications?

Absolutely. It is a general-purpose cable that works in any project where a flexible, well-insulated, and low-diameter conductor is needed: models with LED lighting, dioramas with electrical effects, etc.

The Sloting Plus SP107031 is a 1.5 mm oxygen-free copper (OFC) silicone electric cable, featuring over 70 ultra-fine copper strands for outstanding flexibility and break resistance. Supplied in a 2-metre bag, it is the go-to choice for slot car builders and preparers looking to minimise electrical resistance, improve throttle response and ensure long-lasting, reliable wiring in any slot car or modelling project.
