Why choose it

The fine-stranded copper construction offers excellent flexibility, reducing the risk of breakage during repeated bending or tight installations. The colour-coded red and brown insulation allows quick polarity identification, saving time during assembly and troubleshooting. With a generous 25-meter length, this spool covers multiple small projects without frequent reordering.

Ideal use cases

• Model making and railway electronics
• Low-voltage hobby circuits and Arduino projects
• Internal wiring for small appliances and LED lighting
• Educational electronics labs and prototyping

Good to know

The wire is supplied on a spool for tangle-free storage and easy dispensing. PVC insulation provides good resistance to abrasion and common chemicals, while the 300 V rating suits most low-voltage DC and AC applications. For best results, strip insulation carefully to avoid nicking the fine strands, and use appropriate connectors or solder joints.
