SRML wire is a high-temperature wire that may be used as motor lead wire for hazardous locations. Depending on its conductor size, this wire can be rated to either 150°C or 200°C, but it has an overall voltage rating of 600V. It can also be used as a lead wire for electrical equipment in high-temperature environments. SRML wire performs well where flexibility and fire resistance are important.

Additional Information

What is SRML Wire?

SRML wire stands for "Silicone Rubber Motor Lead" wire, and is often used in various industrial settings where flexible wire with high temperature resistance is needed.

What are common applications for SRML Wire?

SRML wire is valued for its flexibility, durability, and heat resistance characteristics. Some common hazardous industrial applications for SRML wire include:

  • The winding of motors and transformers where large amounts of heat are generated.
  • Industrial machinery as lead wire where a flexible wire is needed while being exposed to hazardous and corrosive environments during operation.
  • Wiring used in Ovens and Furnaces.
  • The flexibility and heat resistance of SRML wire makes it a popular choice as wiring in household appliances such as washing machines, stoves, and refrigerators.
  • Although primarily a Motor Lead wire, SRML may be found in other automotive applications where flexibility and heat resistance is required, such as wiring harnesses, or automotive sensors.
  • SRML wire is also a popular choice in the energy industry. SRML wire is commonly used in power generation and distribution equipment, solar panels, wind turbines, and oil and gas industrial equipment.

It is important to note that while SRML wire has excellent flexibility and heat resistance, it may not be the best choice for your specific application or project.
