Ancor Dark Blue 18 AWG Tinned Copper Wire 500-Foot

The Ancor Dark Blue 18 AWG Tinned Copper Wire is a 500-foot spool of single conductor with Type 3 ultra-flexible stranding.

Dark blue is a function color rather than a power color, and that is why it is stocked. It marks control, signaling and instrument circuits so they are distinguishable from the red and yellow of power wiring in a bundle, which is what makes a large installation traceable years later.

Eighteen gauge suits control, lighting, electronics and signaling circuits at low current. Five hundred feet is a substantial quantity of a wire used in short lengths, which reflects how numerous small circuits are once an instrument or control system is being wired.

Tinned copper strands resist corrosion and electrolysis in damp and salty conditions. Ultra-flexible Type 3 construction routes through consoles, panels and machinery spaces while withstanding vibration and repeated flexing, with insulation staying flexible in extreme cold.
