SRG-K is a premium industrial wire engineered for applications demanding both extreme thermal resistance and superior flexibility. It features a heavy-duty Silicone Rubber core, protected by a fiberglass braid and an outer Kevlar Braided Aramid K-Fiber for enhanced durability. This wire is rated for continuous operation at 200°C and 600V.
The letters in SRG-K denote its primary construction and materials:
SRG-K wire offers several critical advantages for demanding industrial environments:
SRG-K wire is widely utilized in industrial settings where high heat, moisture, and flexibility are simultaneously required. Common applications include:
SRG-K High Temp Wire is designed for demanding electrical applications. It is rated for continuous operation at 200°C (392°F). The voltage rating for this category of wire is 600V.
The Kevlar Braided Aramid K-Fiber outer covering is a critical component of SRG-K wire. It provides superior cut-through and abrasion resistance, significantly improving the wire's mechanical strength and durability in harsh industrial environments. This aramid fiber is exceptionally strong, offering protection against physical damage where other materials might fail.
Yes, SRG-K wire is suitable for environments with moisture exposure. Its silicone formulations are designed to handle UV, ozone, and moisture. Additionally, this wire passes the ICEA T-27-581 Water Absorption Test, confirming its resistance to water.
The exceptional flexibility of SRG-K wire is primarily due to its extruded silicone rubber insulating system and annealed tinned copper conductors. Silicone rubber is inherently soft and pliable, and the cable often utilizes a "Torque Free" design, which eliminates memory found in traditional twisted cables, making it easier to route in tight spaces.
SRG-K wire is designed to meet rigorous industry standards for safety and performance:
Choosing the correct gauge involves assessing several factors to ensure optimal performance and safety:
Yes. We cut SRG-K cable by the foot and orders ship within 1 to 2 days from our distribution centers to keep your project on schedule.

Designed for mission-critical applications, SRG-K is a high-performance 600V industrial conductor built for environments where extreme heat and constant flexibility are essential. The "K" designation represents the Aramid K-Fiber (Kevlar-Fiber) which provides superior cut-through and abrasion resistance. By pairing a high-dielectric silicone rubber insulation with a rugged, saturant-treated fiberglass braid, SRG-K ensures consistent electrical performance in temperatures ranging from -60°C to 200°C. It remains the professional choice for wiring industrial furnaces, heavy-duty motor leads, and heating elements subject to severe thermal stress.
Installation Note: When terminating SRG-K, always use non-insulated high-temperature terminals (brazed or nickel-plated) to match the wire's 200°C rating, as standard plastic-insulated lugs will fail. To prevent the fiberglass braid from fraying after cutting, apply a small section of high-temp heat shrink or fiberglass tape at the termination point. Additionally, because silicone insulation is more susceptible to "tearing" than nylon-jacketed wire, ensure all conduit bushings are installed to avoid dragging the wire over sharp edges during the pull.
