Specifically engineered for high-density power and control applications in extreme thermal zones, this 12 AWG 5-conductor SRG-K assembly provides elite performance where standard cables would degrade. Rated for continuous operation at 200C, this wire combines high-flexibility stranded copper with a specialized silicone rubber and fiberglass armor system.

Why Choose 12/5 SRG-K High Temp Motor Lead?

SRG-K (Silicone Rubber Glass – K-Fiber for Strength) is the industrial standard for “hot-zone” wiring. The12 AWG gauge offers significant current-carrying capacity for heavy-duty motors and industrial heaters. The 5-conductor configuration is highly versatile, commonly used for 3-phase applications requiring a dedicated neutral and ground, or for complex sensor feedback loops in thermal processing equipment.

• Elite Thermal Resilience: Rated for continuous service up to 200C, ensuring electrical integrity in proximity to industrial burners, heating elements, and high-efficiency motors.

• Silicone & Fiberglass Shielding: The silicone rubber insulation provides superior dielectric strength and moisture resistance, while the lacquered fiberglass braid provides essential abrasion resistance.

• Tinned Copper Conductors: The tin coating on the copper strands prevents oxidation and corrosion, which is accelerated in high-heat environments, ensuring long-term termination reliability.

• Extreme Cold Performance: Maintains flexibility and functionality in sub-zero temperatures as low as -60C.
