The cable that won't give you trouble: Ultra Flex 1.5 mm for real slot installations
When it comes to wiring a slot circuit or reviewing the electrical layout of a competition car, the type of cable matters more than it seems. A rigid or low-conductivity cable introduces parasitic resistance, breaks over time, and ultimately reduces the reliability of the setup. The Ultra Flex 1.5 mm cable, 1 metre (ref. SWCA/02) is designed to avoid exactly that.
Main features
- 1.5 mm² cross-section: suitable for current distribution on rails, connecting power supplies to track sections, and other demanding installations.
- Ultra Flex construction: high-flexibility multicore, allowing it to be bent and routed through tight spaces without the risk of breaking the internal conductors.
- 1 metre length: sufficient for most wiring runs in a circuit module or for a specific repair.
- Optimised conductivity: minimises voltage drop in the line, resulting in a more stable power supply for cars on track.
Recommended applications
This cable is particularly useful in two main scenarios:
- Circuit installation and maintenance: connections between the power supply and track connectors, reinforcement of sections with conductivity loss due to oxidation or poor contact, and power wiring in home or club modules.
- Slot car preparation: although the 1.5 mm section is more common in circuits than inside the car, it can be used in modified benches, enhanced braid connections, or customised electrical installations where higher current capacity is required.
Assembly and best practices
To get the most out of this cable, keep the following in mind:
- Strip the end carefully using a calibrated wire stripper: a clean cut ensures a good contact surface when soldering or using connection terminals.
- If you are going to solder it, use high-quality solder and apply heat for just the right amount of time; excessive temperature can melt the insulation or damage the internal filaments.
- Maintain generous bending radii: although the cable is Ultra Flex, permanently forcing very tight angles can compromise the conductor's lifespan.
- Secure the cable run with ties or double-sided tape at passing points to avoid mechanical stress on the solder joints.
Who is this cable for?
Whether you are setting up a new module in your club's venue or reviewing the electrical layout of an already installed circuit at home, this cable offers the necessary flexibility to work comfortably and the appropriate section for efficient current transmission. It also fits well in the workbench of any preparer looking for reliable materials for their installations.
Frequently asked questions
What type of circuit is this cable suitable for?
It is valid for universal rail circuits (Scalextric, Ninco) and Sport rail (Scaleauto, Slot.it, Carrera), both in home installations and club circuits. The 1.5 mm section makes it especially useful in power supply sections where electrical resistance is to be minimised.
Is one metre enough to wire an entire module?
It depends on the size of the module. For a standard module of a couple of linear metres of track, one metre of cable usually covers the power supply run for one rail. For larger installations or with multiple power points, it is common to use several units.
Can I use it inside a slot car?
The 1.5 mm section is generous for the interior of a slot car body, where smaller sections are usually used. However, it can be useful in bench modifications or customised installations where higher current flow is required.
What is the difference between an Ultra Flex cable and a standard one?
An Ultra Flex cable is made up of a greater number of smaller diameter copper filaments, giving it significantly superior flexibility. This facilitates routing through tight spaces, reduces the risk of breakage due to fatigue, and makes soldering more comfortable.
Can it be cut to size?
Yes, without any problem. Coming in 1 metre lengths, you can cut it to the exact length you need for each application.
The Ultra Flex 1.5mm cable (1 metre, ref. SWCA/02) is a high-flexibility multicore copper wire designed for slot car track wiring and power supply connections. With a 1.5mm² cross-section, it delivers reliable current flow with minimal voltage drop, making it a practical choice for both home layouts and club circuits compatible with Scalextric, Ninco, Scaleauto, Slot.it and Carrera track systems. Its flexible construction simplifies routing through tight spaces and ensures durable, clean solder joints for long-lasting electrical installations.
