CB Race Copper Braid Cut: Precise Electrical Contact, Ready to Install

This CB Race copper braid is supplied already cut, allowing for direct installation in the guide without the need for cutting tools or additional measurements. With a thickness of 0.25 mm and width of 3.75 mm, it offers a combination of flexibility and contact surface suitable for stable electrical transmission between the track and the car's electronics.

Function and Performance

The braids are the electrical bridge between the track rails and the car's motor. A worn, oxidised, or inadequately sized braid causes power losses, interruptions, and erratic behaviour on track. Periodically replacing them is one of the simplest maintenance operations with the most direct impact on performance.

Copper is the reference material for this component due to its excellent electrical conductivity and its ability to adapt to the geometry of the guide with use. The section of 0.25 mm thick by 3.75 mm wide is designed for standard format guides commonly found in the slot market.

Assembly and Preparation

Since it comes pre-cut, the replacement process is considerably simplified:

1. Remove the guide from the car.
2. Carefully extract the old braids without damaging the anchors.
3. Place the new copper braids ensuring they are well seated in the guide slots and make clean contact with the motor terminals.
4. Check that there is no play or bends that could interrupt contact.

If the guide or terminals show dirt or oxidation, it is advisable to clean them before installation to ensure maximum conductivity from the outset.

Points to Consider

Always verify that the dimensions of the braid (0.25 mm × 3.75 mm) are compatible with your car's guide before installation. Different manufacturers and models may require different widths or thicknesses. If in doubt, compare with the original braids you are replacing.

Frequently Asked Questions

What advantage does it have that they come pre-cut?

It greatly simplifies the maintenance process: there is no need for special scissors or measuring and cutting at the workbench. They are installed directly, making them particularly practical in a club context or during a race day.

How often should I change the braids?

It depends on usage and the type of track. In regular competition, many drivers check them after each long session or race day. In recreational use, replacement is recommended when power loss, interruptions, or visible signs of wear are observed.

Does the copper material make any difference compared to other materials?

Copper offers superior electrical conductivity compared to alternative materials like steel. This translates into more efficient current transmission and, consequently, a more consistent and predictable motor performance.

Can I use them in any scale?

Compatibility depends on the dimensions of the guide, not directly on the scale. Check that the width of 3.75 mm fits the guide housing of your car before proceeding with the assembly.

The CB Race pre-cut copper braid (ref. SP104126) measures 0.25 mm thick and 3.75 mm wide, providing reliable electrical contact between the slot car guide and the motor. Ready to install without further cutting, it is a practical maintenance component for slot car racing enthusiasts looking for consistent track performance and smooth power transmission.
