Fire-resistant Wires And Cables
Classification :
PRODUCT DETAILS
This product is suitable for circuits that need to maintain normal operation during a fire, such as fire protection systems, emergency lighting systems, life-saving systems, alarm systems, and important monitoring circuits in industrial and civil buildings. It is commonly used in power supply and control circuits for fire pumps, sprinkler pumps, and fire elevators.
Product Description
Fire-resistant wires and cables refer to cables that maintain normal operating characteristics after being burned in a flame for a certain period of time under specified test conditions. According to the standard requirements of GB/T19216-2008 "Line Integrity Test of Cables or Optical Cables under Flame Conditions", fire-resistant wires and cables must burn at 750℃ for 90 minutes without melting the 2A fuse.
Fire-resistant wires and cables use high-temperature resistant organic fire-resistant strips as the fire-resistant layer. According to GB/T19666-2005, fire-resistant wires and cables can be divided into flame-retardant fire-resistant wires and cables and non-flame-retardant fire-resistant wires and cables. Flame-retardant fire-resistant wires and cables mainly meet the flame-retardant characteristics by adding flame retardants to the insulation or sheath. Non-flame-retardant fire-resistant wires and cables are those in which no flame retardants are added to the insulation or sheath. They do not possess flame-retardant properties.
| Flame retardant grade | Fire supply temperature | Fire supply time | The volume of non-metallic materials for laying cables in bundles | Carbonization height | Self-extinguishing time | Applicable products |
| A | ≥815℃ | 40min | ≥7 liters/meter | ≤2.5meters | ≤1h | Flame-retardant and fire-resistant cable |
| B | ≥815℃ | 40min | ≥3.5liters/meter | ≤2.5meters | ≤1h | Flame-retardant and fire-resistant cable |
| C | ≥815℃ | 20min | ≥1.5liters/meter | ≤2.5meters | ≤1h | Flame-retardant and fire-resistant cable |
| D | ≥815℃ | 20min | ≥0.5liters/meter | ≤2.5meters | ≤1h | Flame-retardant and fire-resistant wire |
