Product Overview
ZR-KFGP flame-retardant silicone rubber control cables deliver unmatched performance in extreme industrial environments. Designed for 450/750V control circuits, these cables combine fluoroplastic insulation with silicone rubber sheathing and copper braid shielding to withstand continuous temperatures from -60°C to +180°C (200°C peak). Ideal for steel mills, power plants, petrochemical facilities, and aviation systems where high-temperature stability, chemical resistance, and flame retardancy are critical.
Key Features & Benefits
