Specifically engineered for extreme thermal environments, this 12 AWG 7-conductor SRG-K assembly is the definitive solution for high-temperature motor leads and industrial heating controls. Rated for continuous operation at 200°C, this wire features high-flexibility stranded conductors protected by a dual-layer silicone rubber and fiberglass braid system, ensuring electrical integrity where standard cords would fail.
SRG-K (Silicone Rubber Glass - K-Fiber for Strength) is designed to thrive in the "hot zones" of industrial machinery. The 12 AWG gauge provides robust current-carrying capacity, while the 7-conductor configuration allows for complex multi-phase motor wiring or bundled control signals within a single high-heat assembly.
Extreme Thermal Endurance: Rated for continuous use up to 200°C, making it ideal for leads on high-efficiency motors, commercial ovens, and industrial furnaces.
Superior Flexibility (Class K): Utilizes high-strand count copper, allowing the conductors to be routed through tight conduits and around sharp bends in thermal equipment without work-hardening.
Dual-Layer Protection: The silicone rubber insulation provides excellent dielectric strength and moisture resistance, while the lacquered fiberglass braid offers superior abrasion resistance and protection against mechanical stress.
Specialized Color Coding: Features a 7-color identification system (including the Red/Black stripe) for precise circuit mapping in complex control environments.
Conductor Size: 12 AWG
Number of Conductors: 7
Color Code: Black, Red, Blue, Orange, Yellow, Brown, Red/Black Stripe
Voltage Rating: 600V
Max Temperature: 200°C
Insulation Material: Silicone Rubber
Outer Jacket: Fiberglass Braid with High-Temp Finish
Conductor Material: Stranded Tinned Copper
Standards: ICEA T-27-581, IEEE-383, NEMA WC 3, ROHS Compliant
High-Temperature Motor Leads: The primary choice for connecting motors in industrial fans, blowers, and pumps exposed to high ambient heat.
Industrial Oven & Furnace Controls: Ideal for routing power and sensor signals through the thermal envelope of heat-treating equipment.
Commercial Food Equipment: Frequently used in high-capacity rotisseries, broilers, and industrial baking systems.
Foundry & Glass Manufacturing: Perfectly suited for machinery operating in close proximity to molten materials or high-intensity infrared heaters.
Technical Note: All values are nominal and subject to industry tolerances and manufacturer corrections. Specifications are subject to change without notice. It is the buyer’s responsibility to verify that all materials meet the specific requirements of the project and comply with local electrical codes.
*All values are nominal and subject to correction. Ampacity must be calculated based on the specific ambient temperature and the thermal limits of the termination points.

This 12 AWG, 7-conductor wire is a high-performance industrial cable designed for the most demanding thermal environments. Rated for continuous operation at 200°C (392°F), it is the specific choice for the internal wiring of large electric motors, industrial furnaces, and glass-working machinery. While standard cables would melt or harden under these conditions, SRG-K maintains its electrical integrity and flexibility, preventing catastrophic system failures in high-heat zones.
The SRG-K architecture is a tiered defense system against heat and mechanical stress:
A 7-conductor cable at 12 AWG provides significant power capacity alongside multiple control pathways:
At 200°C, standard bare copper oxidizes rapidly, leading to increased resistance and eventual connection failure.
12/7 SRG-K is engineered to perform where standard industrial cables fail:
That is a specialized fiberglass jacket. Think of the silicone underneath as the "skin" that keeps the electricity in, and the fiberglass as the "armor." Because silicone is soft and can be easily torn, the fiberglass braid protects it from being scraped or cut when you're pulling it through the tight metal parts of a motor or oven.
