Silicone Sleeve with Copper Wire (OFC)

OFC Cable with Silicone Sheath: Conductivity and Flexibility for Your Slot's Electrical Installation

The Silicone Sheath with OFC Copper Wire from Sloting Plus (ref. SP107041) is an electrical cable specifically designed for applications where the quality of conduction and the durability of wiring make a real difference. With a total diameter of Ø 1 mm, it conceals more than 70 ultra-fine copper strands braided together, providing outstanding flexibility and notable resistance to breakage due to fatigue.

Main Features

• OFC Copper (Oxygen Free Copper): oxygen-free copper, with a purity superior to standard copper. It improves electrical conductivity and reduces signal or current losses, especially relevant in circuits where every milliamp counts.
• More than 70 braided strands: the high number of ultra-fine strands instead of a solid core or a few thick strands is what makes this cable so flexible and resilient. Bend, curve, and redirect the wiring without the risk of it breaking internally.
• Silicone sheath: the exterior silicone insulation withstands temperature variations and repeated friction better than conventional PVC. Ideal for installations where the cable passes through hot areas or is subjected to movement.
• Total diameter Ø 1 mm: compact section that facilitates passage through tight spaces without sacrificing conduction capacity.
• Presentation: bag containing 2 metres of cable.

Function and Performance

In the world of slot racing, the quality of the internal wiring of a car or a home track installation is often overlooked, but it directly influences the motor's response and the stability of driving. A cable with high conductivity and low internal resistance transmits the signal from the controller to the motor better, with less energy loss along the way. The OFC wire from Sloting Plus meets this need exactly: it offers clean and continuous conduction, without the micro-cuts that can occur in lower quality cables when bent repeatedly.

The silicone sheath adds an extra layer of safety in permanent or semi-permanent installations, where the cable may come into contact with hot surfaces — such as the casing of a motor that operates during long sessions — without the insulation deforming or losing its dielectric properties.

Compatibility and Applications

This cable is suitable for any low-voltage electrical application in the slot hobby:

• Replacement or upgrade of internal wiring in slot cars (connections between braids, motor, and guide).
• Connections in handmade or competition motor benches.
• Wiring of electronic accessories in home tracks.
• Any modelling or hobby electronics project that requires a flexible cable with good conductivity in a small section.

Assembly and Preparation

As this is a very fine multi-strand cable, it is advisable to carefully strip the end of the silicone sheath with a wire stripper suitable for the diameter, avoiding cutting the inner strands. For soldering, it is recommended to pre-tin the tip of the cable — a process known as "pre-tinning" — before joining it to the final soldering point. This facilitates a clean joint and ensures that all strands are well integrated at the contact point.

Frequently Asked Questions

What is the difference between an OFC cable and a standard copper cable?

OFC copper (Oxygen Free Copper) has been refined to remove dissolved oxygen from its structure. This results in slightly superior electrical conductivity and greater resistance to internal corrosion over time. In low-voltage applications like slot racing, the most noticeable difference is the long-term stability of conduction.

Why does it matter that the cable has more than 70 fine strands instead of one or a few thick strands?

Fine multi-strand cables are much more flexible and better withstand repeated bending cycles without the internal strands breaking. In a slot car, where the wiring is subjected to vibrations and small constant movements, a multi-strand cable lasts significantly longer than a rigid core one.

Does the silicone sheath withstand high temperatures better than PVC?

Yes. Silicone maintains its insulating properties over a wider temperature range than conventional PVC. In installations near motors that heat up during long racing sessions, the silicone sheath does not soften or stick to other surfaces, which also facilitates future maintenance of the wiring.

Can I use this cable on the track as well as in the car?

Yes. Its Ø 1 mm section makes it suitable for both internal wiring of slot cars and small connections in the electrical installation of a home track: joints between rails, auxiliary power connectors, or similar.

How many metres does the bag contain?

Each bag contains 2 metres of cable.
