SRG-K HIGH TEMP WIRE

SRG-K is a premium high-temperature industrial wire designed for applications requiring both extreme thermal resistance and superior flexibility. The "K" designation refers to its Kevlar Braided Aramid K-Fiber, which provides superior cut-through and abrasion resistance. The insulation consists of a heavy-duty Silicone Rubber core protected by a closely woven fiberglass braid finished with a high-temperature saturant. Rated for continuous operation at 200°C and capable of handling 600V, SRG-K is the industry standard for environments where heat, moisture, and flexibility are all required simultaneously.

SRG-K High-Temperature Wire (600V)

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.

Key Features
  • 200°C Thermal Rating: Engineered to maintain electrical integrity in ambient temperatures that would destroy standard PVC or XLPE wiring.
  • Silicone Rubber Insulation: Offers excellent dielectric strength and remains pliable in extreme cold (-60°C) as well as extreme heat.
  • Fiberglass Braid Jacket: Provides a rugged outer layer that protects the silicone core from mechanical abrasion, fraying, and accidental contact with hot surfaces.
  • 600V Industrial Grade: Fully rated for primary power and control circuits in heavy-duty machinery.
  • Chemical & Flame Resistance: The silicone/fiberglass combination is naturally flame-retardant and resists many common industrial oils and solvents.
Common Applications
  • Industrial Ovens & Furnaces: The primary wiring for heating elements and sensors in commercial baking and heat-treating facilities.
  • Motor Lead Wire: Used as flexible leads for high-efficiency motors (Class H) that run at elevated internal temperatures.
  • Commercial Kitchen Equipment: Internal wiring for industrial ranges, fryers, and steam tables.
  • Plastic Injection Molding: Providing power to heater bands and thermocouples on molding machines.
  • Drying & Curing Equipment: Used in automotive paint booths and textile drying racks.
  • Lighting Fixtures: Wiring for high-intensity discharge (HID) lamps and commercial kilns.
  • Steel & Glass Manufacturing: Routing control signals near molten material processing lines.
