SZ-K Cable Description
SZ-K cables use silicone rubber insulation, capable of withstanding extremely high thermal stress (up to 150°C), making them ideal for demanding industrial environments. The cable is flame-retardant, producing minimal smoke and no toxic gases when burning.
It is resistant to UV radiation, chemical reagents, and low temperatures, making it suitable for both indoor and outdoor installations. It is commonly used in fire alarms, emergency circuits, ventilation systems, and other industrial machinery with extremely high fire safety requirements.
