In modern buildings and industrial facilities, the power system operates like a "blood vessel", and the continuous power supply capacity in fire scenarios is directly related to personnel safety and the operation of critical equipment.Flame retardant and fire-resistant cables, with their dual characteristics of "flame propagation prevention+fire resistance and power protection", have become the "fireproof armor" that safeguards life and property safety. The selection of their application locations should closely follow the three principles of "key scenarios, continuous power supply, and fire prevention priority".

　　1、 Personnel intensive places: life support for evacuation and rescue

Once a fire breaks out in densely populated places such as shopping malls, theaters, and sports centers, rapid evacuation and emergency rescue are crucial. Flame retardant and fire-resistant cables are mainly used for emergency lighting systems, evacuation signs, and fire broadcast lines in these places. For example, the evacuation lighting in shopping malls needs to be continuously powered for at least 90 minutes during a fire to ensure that personnel can see the escape route clearly in the smoke; If the stage lighting control line of the theater uses ordinary cables, the fire may quickly spread to the equipment room and cause secondary disasters. However, this product can not only delay the spread of the fire, but also maintain the operation of the control system in the early stages of the fire, buying time for actors and audiences to evacuate. In addition, emergency power lines at subway carriage connections and fire elevator control lines in high-rise office buildings also rely on such cables to ensure the safe evacuation of passengers in the event of a power outage.

　　2、 Critical infrastructure: the 'nerve center' that maintains social functioning

Hospitals, data centers, communication base stations, and other facilities have high requirements for power continuity. The power supply lines in the operating rooms and ICU wards of hospitals must use fire-resistant cables - if the power supply is interrupted during a fire, it may endanger the lives of patients; After using flame-retardant and fire-resistant cables for the core routers and server UPS power lines in the data center, data storage and transmission can be maintained in case of a fire in the computer room, avoiding the loss of important information; If the signal transmission line of a communication base station fails in a fire, it will cause widespread communication interruption, and the continuous power supply capability of fire-resistant cables can ensure the operation of emergency equipment in the base station and maintain basic communication functions. In addition, control cables for substations and excitation system lines for power plants also require such cables to protect the power grid dispatch center from damage in the event of a fire.

　　3、 Industrial high-risk areas: the "isolation zone" to prevent the chain reaction of disasters

The control circuit of reaction vessels in petrochemical enterprises and chemical plants, as well as the power supply line of fire pumps in oil depots, are typical application scenarios. If the instrument control cables of petrochemical plants fail in a fire, it may lead to uncontrolled reactions and explosions; After using this product for the fire sprinkler system and foam fire extinguishing device power supply line of the oil depot, water can be continuously supplied to extinguish the fire in case of oil leakage, so as to prevent the fire from spreading to the storage tank. The ventilation fans and gas monitoring sensor circuits in coal mines also rely on such cables - if ventilation is interrupted during a fire, toxic gases will quickly spread, and the fire-resistant performance of fire-resistant cables can ensure the operation of ventilation systems and monitoring equipment, buying time for miners to escape.

From shopping malls to operating rooms, from data centers to chemical plants, the application of flame-retardant and fire-resistant cables always revolves around the core requirement of "uninterrupted critical functions and no spread of fire". Correctly selecting and installing such cables is not only a mandatory requirement to meet fire safety regulations, but also a strong commitment to life safety and social responsibility.
