Superconducting fine wire

Conductivity, flexibility and durability combined in a high-performance wire

The fine superconductor TT500B wire from Tectime represents a direct evolution from its predecessor. Manufactured under stringent production standards, it simultaneously improves electrical conductivity, ductility, and mechanical strength, three factors that make a difference in a well-executed electrical installation within competitive or prepared slot racing.

Main features

• Diameter: 1.7 mm, fine and manageable, ideal for installations in tight spaces.
• Microfilaments: 90 microfilaments inside that ensure superior conductivity and flexibility, making it easy to lay the wire without the risk of breakage.
• Length: 1 metre per unit.
• Coating: high-quality silicone that provides exceptional flexibility, high heat resistance, and robustness against breakage far exceeding standard market wires.
• Enhanced conductivity: superconductor design that reduces electrical resistance and optimises current transfer between the source and the motor.

Function and performance

In slot racing, the quality of the wiring is one of those details that separates an amateur preparation from a truly refined one. A wire with high internal resistance robs energy from the motor before it reaches where it needs to go. The TT500B minimises that loss thanks to its structure of 90 microfilaments, which increases the effective conductive cross-section while maintaining a very compact physical profile.

The silicone coating is not a minor detail: it withstands well the temperatures that the electronics of a car can reach during long sessions, does not harden over time as conventional PVC does, and allows the wire to be bent at tight angles without the insulation cracking.

Compatibility and applications

Its fine and flexible format makes it especially useful for internal wiring of slot cars in any scale, as well as for connecting braids, motors, and electronics in competition chassis. It is also suitable for small modelling projects that require manageable, low-resistance wire.

Assembly and preparation

When working with superconductor wires of multiple microfilaments, it is advisable to use calibrated stripping tools to avoid damaging the filaments when removing the insulation. Poor stripping can disable several of those microfilaments and reduce the actual conductivity of the wire. It is recommended to solder with good quality tin and apply heat quickly and precisely to avoid degrading the silicone coating adjacent to the joint.

Frequently asked questions

What advantage do the 90 microfilaments provide over a conventional wire?

A greater number of microfilaments implies a more uniform and flexible conductive cross-section. The wire bends easily without breaking internally, and the electrical resistance is lower, resulting in a more efficient energy transfer to the motor.

Does the silicone coating withstand the heat from the motor and electronics?

Yes. The high-quality silicone tolerates significantly higher temperatures than standard PVC and does not harden or crack with continued use, extending the lifespan of the wire.

How many metres does each unit include?

Each unit contains 1 metre of wire.

Is it suitable for competition chassis on club tracks?

Perfectly. Its fine profile facilitates installation in chassis with limited space, and its low internal resistance is exactly what is sought in a competition-oriented preparation.

Can I use it to connect the braids to the motor?

Yes, it is one of its most common uses. Its flexibility and reduced cross-section make it ideal for that connection without adding unnecessary weight or volume to the assembly.

The Tectime TT500B is a thin superconductor wire featuring 90 microfilaments, 1.7 mm diameter and a high-quality silicone insulation. Designed for slot car preparation and competition, it delivers improved electrical conductivity, outstanding flexibility and superior heat resistance compared to standard wiring. A 1-metre length per unit makes it a reliable choice for internal wiring in slot cars, motor connections and precision electronics in scale modelling projects.
