Product Overview
KGG series silicone rubber control cables deliver unparalleled performance in extreme-temperature industrial environments. Engineered for control and monitoring circuits (450/750V), these cables feature all-silicone construction with optional shielding/armoring for critical applications in steel plants, smelters, power generation, petrochemical facilities, and aviation. Withstanding temperatures from -50°C to +180°C, they offer exceptional flame retardancy, radiation resistance, and mechanical durability.
