Rowe SW185M3050 HV High-Voltage Lead Wire 18 AWG 25kV DC 50 ft Red

SKU CH-M40K-FYNZQ

High-voltage lead wire with 18 AWG nickel-plated copper conductor, silicone insulation and 25 kV DC rating in a 50 ft red jacket rated to 482 °F

  • TypeWire & Cable
  • Rated for 25 kV DC high-voltage applications

High-voltage lead wire for 25 kV DC circuits

This 18 AWG nickel-plated copper wire carries a 25 kV DC rating and comes in a 50 ft red silicone-insulated length. It is built for high-voltage hook-up in industrial, automotive or laboratory equipment where reliable insulation and temperature resistance are required. The conductor uses nickel-plated copper for stable conductivity at elevated temperatures.

Fits high-voltage assemblies needing 18 AWG

The wire integrates into existing harnesses or custom cable builds that specify 18 AWG conductors and silicone jacketing rated to 482 °F. Its flexible silicone insulation allows routing in tight enclosures while maintaining dielectric strength at the full 25 kV DC rating. The red jacket provides clear circuit identification alongside other colour-coded leads.

Replaces lower-voltage

When an existing lead is rated below 25 kV DC or uses insulation that cannot withstand 482 °F, this wire upgrades the safety margin without changing conductor gauge. The jump is worth it when the application demands both the higher voltage rating and the high-temperature silicone jacket simultaneously.

Questions about this item

What is the maximum continuous voltage this 18 AWG lead wire is rated for?

The wire carries a 25 kV DC rating, which is the highest sustained voltage the insulation is designed to withstand.

How hot can the silicone insulation get before it degrades during all-day operation?

The insulation is rated to 482 °F, so it tolerates continuous high-temperature environments without breaking down.

Which conductor material must the mating connector or terminal be compatible with?

The conductor is nickel-plated copper, so crimps, lugs or splices must be rated for that plating to ensure a reliable joint.
