Fire-resistant cable is designed to maintain safe operation for a certain period under high temperatures or fire conditions. Its core feature lies in the use of special materials (such as mica tape, ceramifiable silicone rubber, etc.) and structural designs that ensure circuit integrity. Typically, it can sustain power transmission for over 90 minutes in flames ranging from 750 °C to 1000 °C. This type of cable is widely used in high-rise buildings, subways, power stations, and chemical plants—places with stringent fire safety requirements. According to standards, fire-resistant cables are classified into Class A (950 °C/90min) and Class B (750 °C/90min). Some products also combine flame retardant and low-smoke halogen-free properties, effectively slowing the spread of fire and reducing toxic smoke, thus gaining crucial time for evacuation and firefighting efforts.
