There are various types of fire cables, mainly classified according to their usage environment and performance requirements. Here are some common types of fire cables:
1. Flame resistant cable: A flame resistant cable is a cable that can prevent the spread of fire during a fire. The insulation and sheath materials are made of flame-retardant materials, which can self extinguish during combustion and prevent the fire from spreading. This type of cable is suitable for places that require flame retardant performance, such as high-rise buildings, underground railways, stations, airports, hospitals, etc.
2. Fire resistant electrical cable: Fire resistant electrical cable can maintain normal operation for a long time under high temperature and has certain fire resistance performance. Its insulation and sheath materials are made of high-temperature materials, which can withstand the electrical and mechanical performance requirements in high-temperature environments. This type of cable is suitable for places where equipment needs to operate normally for a long time during a fire, such as fire control rooms, emergency lighting systems, automatic fire alarm systems, etc.
3. Low smoke and halogen-free cables: Low smoke and halogen-free cables produce less smoke during combustion, do not release toxic gases, and are more conducive to personnel evacuation and fire rescue. The insulation and sheath materials are made of low smoke and halogen-free materials, which meet environmental protection requirements. This type of cable is suitable for places with high requirements for environmental protection and personal safety, such as subways, tunnels, high-rise buildings, etc.
4. Mineral insulated cables: Mineral insulated cables use minerals as insulation materials, which have excellent fire resistance and high temperature stability. It can maintain electrical performance for a long time at high temperatures, is not easy to burn, and does not produce toxic smoke. This type of cable is suitable for places with extremely high fire resistance requirements, such as high-rise buildings, petrochemical enterprises, etc.
