Reely SIFF Silicone Wire 1 x 2.5 mm² Black 5 m

High-current connections in RC models and electronics often fail when standard PVC wire melts or stiffens under load. The Reely SIFF silicone wire solves this with a tinned copper conductor and heat-resistant silicone insulation that stays flexible from -60 °C to +180 °C.

Who is it for

Model builders, RC enthusiasts, and electronics technicians who need reliable, flexible wiring for high-temperature or high-current applications such as battery leads, motor connections, or industrial equipment.

Main features

• Silicone insulation remains flexible in extreme cold and heat
• Tinned copper conductor resists corrosion and simplifies soldering
• Fine-stranded (Class 5) for easy routing in tight spaces
• Rated for 600 V and approximately 25 A in free air
• Inherently flame-retardant silicone insulation
